摘要： PROBLEM TO BE SOLVED: To provide a gas blast-circuit breaker for performing prohibiting setting in which a gas cutoff valve is not closed by detection of abnormalities by an external sensor in inspection of the flow rate detecting operation. SOLUTION: In a gas blast-circuit breaker provided with a structure for performing the gas cutoff operation by detection of the flow rate and detection of abnormalities of the outside, setting in which the gas cutoff operation by an external part abnormality judging part 6 in inspection of the flow rate detecting operation is performed by a control signal to be input from an external communication part 3 by communication. When the external part communication part 3 receives the control signal, an external part input control part 4 performs prohibition setting of the judging operation of the external part abnormality judging part 6. Since the prohibition setting is released when a flow rate judging part 7 outputs a cutoff request signal, the inspection of the flow rate detection can be performed without being affected by the gas cutoff operation by the external part abnormality judgement.

摘要： PROBLEM TO BE SOLVED: To provide a gas-blast circuit breaking device that can execute a gas leak inspection without misjudgment at the time of releasing the closed state of a cutoff valve based on abnormality detection to reset it to a normal state. SOLUTION: Upon the input of a reset signal from a reset signal input part 7 for normal resetting at the time of a cutoff valve 6 being closed due to detection of an abnormal state, a valve opening/closing signal is outputted from a valve opening/closing control part 8 to put the cutoff valve 6 in opening/ closing action, and pressure is charged to execute a gas leak inspection. In order to measure pressure for the gas leak inspection after the lapse of specified time when pressure fluctuated by opening/closing of the valve is stabilized, the specified time is clocked by a stand-by timer 9, and then pressure is measured to judge gas leak. In case of no gas leak, a valve opening signal is outputted, so that a cutoff valve driving part 11 opens a cutoff valve to reset it to a normal state.

摘要： PROBLEM TO BE SOLVED: To provide a gas-blast circuit breaking device that can open a cutoff valve closed at the time of consumption of a battery, a power source of the gas-blast circuit breaking device, according to a specified rule. SOLUTION: Specified battery consumption voltage before reaching the lower limit value of battery consumption of a battery power source 10 is detected by a voltage drop detecting part 2, and a cutoff valve 9 is closed by a gas-blast circuit breaking control part 6, while the cutoff valve 9 can be opened when an opening receiving part 3 receives an opening demand. A timer part starts counting from the time of detecting the battery consumption voltage. After the lapse of preset specified time, opening action is stopped by an opening function stop part 5, and a gas passage is cut off again by the cutoff valve 9. With this action, gas is usable until a gas-blast circuit breaking device is replaced due to battery consumption.

摘要： PROBLEM TO BE SOLVED: To secure safety in using gas with a cell of small capacity for a long time. SOLUTION: Based on the phenomena of shut-of and unplugging, it is stored in a shut-off state memory part 5 by a shut-off phenomenon outbreaking part 1 and an unplugging phenomenon outbreaking part 4 whether a gas shut-off valve 3 is in a shut-off condition or a plug opening condition, and when the shut-off phenomenon outbreaks, the shut-off phenomenon outbreaking part 1 allows a gas interruption ordering part 2 to refer it to the state of the gas shut-off valve 3 stored in the shut-off state memory part 5, it is thereby so designed that when the valve is is shut off no shut-off order to the gas shut-off valve 3 is outputted, and when a plug is found to have been opened, a shut-off order is thereby outputted so that the gas shut-off valve 3 is intended to be driven less frequently.

摘要： PROBLEM TO BE SOLVED: To automatize opening of a valve by instructing the time, reconcile safety and convenience, and improve reliability of a gas interruption apparatus. SOLUTION: A valve opening time instruction signal B is outputted from a sensor monitoring part 1 through a communication receiver part 2, and a valve is opened with a valve opening/closing driving part 4 following a valve opening signal C when the time reaches a specific time set in association with the valve opening instruction time in a valve opening instruction part 3. Further, the existence of leakage is judged in a leakage detection part 6 based upon a flow rate signal of a flow rate detection part 5 whereby a gas use allowance signal or a gas use interruption signal is outputted. When the gas use interruption signal E is outputted, a valve closing instruction part 7 outputs a valve closing signal H and hence the valve opening/closing driving part 4 closes the valve.

摘要： PURPOSE:To improve reliability by preventing erroneous stop from being generated again by re-registering the learnt result when the erroneous stop occurs after learning is completed. CONSTITUTION:A flow rate signal G from a flow rate measuring means 1 is calculated into a real flow rate P1 by a flow rate arithmetic part 2. During a prescribed learning term, a learning processing part 3 calculates a flow rate pattern Q as the learnt result and holds it. Further, a flow rate decision part 4 receives the flow rate pattern Q from the learning processing part and a flow rate pattern P2 from the flow rate arithmetic part and compares them and in the case of abnormality, a stop/alarm signal R is outputted. A stop alarming means 5 issues an alarm or stops a gas route. While receiving the signal of this flow rate decision part 4, a stop flow rate storage part 6 stores a flow rate pattern F at the time of stop. Corresponding to an input from the outside, a reregister signal T is outputted by an erroneous stop time reregister signal input means 7. An erroneous stop time reregister processing part 8 instructs the holding of the flow rate pattern F in the stop flow rate storage part 6 to the learning processing part 3 and updates the learnt result.

摘要： PROBLEM TO BE SOLVED: To provide a gas cutoff device provided with the function to detect a closed state and raise an alarm informing when a cut-off valve cuts off a gass passage due to the shock. SOLUTION: When a cutoff valve closes a plug and moves, a valve drive section 4 outputs a cutoff valve release signal B. When the cut-off valve release signal B is outputted due to the shock, since a cut-off request signal A is not outputted from a valve drive request section 3, a shock signal input section 5 judges to have been the shock and outputs a shock detect signal C. Since a shock judgment delay section 6 outputs the shock judgment request signal E after a prescribed delay time lapsed, an open and close valve judgment section 7 confirms the opened and closed state of the cut-off valve and when the closed state is detected, it outputs an alarm informing signal D and an alarm information is raised from an alarm informing section 8. Since the open and closed valve is judged after the vibration is settled by setting up the said delay time, no misjudgment is made.

摘要： PROBLEM TO BE SOLVED: To provide a gas shutoff device capable of detecting a gas leakage whose flow rate is identical to the flow rate of a pilot light even when a registered flow rate of a pilot light is changed by the replacement of a gas apparatus or the like. SOLUTION: A pilot light flow rate determinant section 3 compares a measured gas flow rate value A with a pilot light flow rate holding value which is a registered pilot light flow rate value and outputs a non-identical signal D when they are not the same and an identical signal E when they are the same. When the input of the non-identical signal D is continued for a specified time, an alarm annunciation section executes alarm information. When a specified time has elapsed from the input of the same signal E, a pilot light flow rate erasure determinant section 6 outputs a pilot light flow rate registered deletion signal F to a pilot light flow rate holding section 4, thereby eliminating the pilot light flow rate holding value C.

摘要： PROBLEM TO BE SOLVED: To eliminate the effect of a transient noise or the like and prevent the occurrence of erroneous judgement by applying the constitution that an input port judgement part inspects voltage, upon receipt of a port judgement normal signal, the abnormality of a circuit is judged when the voltage is equal to or below the preset level and, then, the circuit abnormality is reported. SOLUTION: An input port judgement part 5, upon receipt of an output signal from a periodic timer part 1 to periodically output a voltage inspection signal A, judges the status of an input port and outputs a port judgement normal signal D and a port judgement abnormality signal E. A voltage detection part 2, upon receipt of the port judgement normal signal D, inspects voltage. Then, the voltage detection part 2 outputs a voltage drop signal B, when the voltage is equal to or lower than the preset value, and a voltage normal signal C when the voltage is abnormal. Also, a circuit abnormality judgement part 6, upon receipt of the port judgement abnormality signal E, identifies a circuit abnormality and outputs a circuit abnormality reporting signal F. In this way, the input port judgement part 5 judges the status of the input port to read a judgement signal for voltage inspection, before implementing the inspection, thereby avoiding judgement about a voltage drop in the case of an abnormality.

摘要： PURPOSE:To improve reliability and safety by deciding stop corresponding to the use pattern of a gas equipment and the simultaneous start of individual equipments. CONSTITUTION:An individual equipment estimating means 2 estimates the individual equipment by the increase/decrease of a flow rate and outputs an estimated individual arithmetic flow rate. While a timer 3 is operated by an individual flow rate registration starting means 4, an individual flow rate storage means 5 registers this estimated individual arithmetic flow rate. After the timer 3 is stopped, an abnormality decision part 6 outputs an individual abnormal signal to an alarming means or stopping means 7 when the estimated individual arithmetic flow rate is not contained in the individual flow rate stored in the individual flow rate storage means 4.
