摘要： PURPOSE:To remove an irritating odor by controlling acceleration in corrosion of a metallic material, by a method wherein a filter is provided to an air intake part of which wetness has been given, and formaldehyde is removed even in air containing humidity. CONSTITUTION:As for an indoor air cooler body 1, it is provided with a cooler 3, a cooling medium is made to circulate through a radiating part 4 by compressing the same and air from an air intake part is cooled by making the air expand at this part. The air intake part 8 is provided with a dust filter 11 provided on the inside of a cover and a wet filter 12 provided on the inside of the dust filter 11. As for the wet filter 12, wetness is given to the same by treating a filter material with an agent whose moisture absorption is high such as lithium chloride or magnesium chloride or calcium chloride or glycerin. With this construction, even under circumstances containing moisture a matter that either corrosion of a metallic material is controlled or an irritating odor is removed is performed by removing formaldehyde.

摘要： PURPOSE:To prevent corrosion of metallic material by agitating and circulating the air in the title board and drawing gaseous NH3 generated from the electrical parts with a fan and bringing it into contact with a filter stuck with acid. CONSTITUTION:A monitoring and controlling device 5 is constituted of the electrical parts 6 made of phenol resin and gaseous NH3 is generated from the electrical parts 6. The gas 14 contg. NH3 is sucked with a fan 12 and passed through the air window 11a of a case 11 and brought into contact with a filter 16 made of filter paper stuck with acid and thereby gaseous NH3 is extinguished by chemical reaction. Since NH3 concn. is reduced from the air in the board, corrosion of metallic material and generation of stress corrosion cracking of brass material are prevented.

摘要： PURPOSE:To achieve system separation quickly by a method wherein a system separation switch is provided at a system linkage point between the power system of a power company and the power system of a private generator and undervoltage relays and an excessive current relay are provided and, when operation signals of both the relays exist, a trip instruction is outputted. CONSTITUTION:When a service interruption failure occurs, it is judged whether the action of a power company side gives an overload to a small capacity generator G1 and the overload exceeds an allowable limit or not and then a system linkage point breaker CB-A is opened. By combinations of undervoltage relays 1 and 2 and an excessive current relay 5, the failure phenomenon can be detected quickly. Before the revolution of the small capacity generator G1 is declined by an impact of an overload, the small capacity generator G1 is separated from the power system of the power company. Therefore, the output decline of a main load L11 connected to the small capacity generator G1 system can be restored in an early stage. Further, production loss caused by the interruption can be avoided.

摘要： PURPOSE:To prevent a wrong trip by connecting two auxiliary relays to be operated with the closing signal with time limits different from each other to an operating circuit of a leased breaker. CONSTITUTION:In the case that an A power capacitor bank leased breaker 52AC is operated for input during the stop of a B power capacitor leased breaker 52BC, when an operating switch 3-52AC of the breaker 52AC is operated for input, a holding relay 52ACX is excited to turn ON a usually open contact 52ACX-a. A time limit relay 52ACXT1 is thereby operated with a time limit to close the breaker 52AC, and the current flowing to the breaker 52AC becomes maximum at the initial time, and thereafter, it is reduced to be the mean rated current. At this stage, even if the current becomes maximum, an induction disc element 51AC-INDU of an overcurrent relay 51AC does not reach the operating condition, and even if a holding relay 52BCX-b connected to the element 51AC-INDU is turned ON, the breaker 52AC does not trip. But, an instantaneous element 51AC-INST is operated in response to the accident detecting current. A wrong trip can be thus prevented.

摘要： PURPOSE:To prevent a trouble due to a corrosion by providing a vent port at a part of a housing of a sealed structure, and providing a filter made of metal fiber of nickel or tin, connected to the port. CONSTITUTION:An opening 5 is provided at the top of a housing in a control board, a filter case 8 having a small opening at the atmospheric side to be connected to the opening 5 is mounted, nickel fiber 6 is filled therein, and respiration air stream 7 can freely pass by a respiration due to temperature change of the atmosphere. When temperature in the board drops due to the temperature change of the atmosphere and the atmospheric air is invaded into the board 1, the fiber 6 is chemically reacted with sulfurous acid gas contained in the atmosphere, and fresh air which does not almost contain the gas is supplied from the opening 5 into the board.

摘要： PURPOSE:To provide a safety and highly reliable gas-blast circuit-breaker by separately providing an operating mechanism for operating a circuit breaking part and a control part for controlling the operation of the operating mechanism. CONSTITUTION:The circuit breaking part 1 of a gas-blast circuit-breaker is put on a frame 2, and an operation box 3 and an exclusive supervisory and control box 6 are separately mounted on the frame 2. The operating force from the operation box 3 is transmitted to the circuit breaking part 1 through a connecting rod 4. On the other hand, the operation box 3 is connected to the exclusive monitoring control box 6 through an electric wiring 7, and a communication electric signal with the outside is communicated by mounting a cable pipe 5 on the exclusive supervisory and control box 6. Since the assembling of the operation box mainly consisting of an operating mechanism and the assembling of a gas system and a monitor control electric system can be separately performed, for the manufacture in factory, the work can be simplified. Further, the operation and centralized control of exclusive supervisory and control system for summarizing a plurality of gas-blast circuit-breakers in one place can be performed.

摘要： PURPOSE:To prevent corrosion on electric appliances by providing a filter which is impregnated with an alkali solution at the air intake section and removing by chemical reaction the acidic gases in the sucked air. CONSTITUTION:An air intake section 6 is constituted of an acidic gas removal filter 8 which is received in its inside, a dust removal filter 10, a protection frame 11 mounted removably to the outside of a case 9, etc. The acidic gas removal filter 8 is made of a filter paper which is impregnated with a potassium carbonate solution and dried naturally later. When a fan 5 is driven, polluted air containing an acidic gas such as nitrous acid gas, sulfurous acid gas, hydro gen chloride, etc. is sucked as shown by the arrow mark 12 and it contacts the dust removal filter 10 to be removed of dusts, and later contacts the acidic gas removal filter 8. On this contact chemical reactions take place and an acidic gas such as sulfurous acid gas, nitrous acid gas, hydrogen chloride, etc. is removed. Troubles by corrosion on electric appliances can, therefore, be prevented.

摘要： PURPOSE:To prevent an overload operation by providing a load breaker for selecting a load to be cut-off and a selecting and cutting-off state display lamp of a load to be disconnected at the time of separating a system if a non-utility generator facility is separated from an electric power company. CONSTITUTION:Power is received from an electric power company system 1 by a power receiving breaker 4, and a non-utility generator facility 2 is connected to a power distribution bus 18 via a generator breaker 16. Protective loads 11 and 12 are connected to breakers 7, 8, and selectively breaking loads 13, 14 are connected to breakers 9, 10. The breaker of a selectively cut-off state lights a selectively cut-off state display lamp 21, and the breaker of a trip blocking state lights-off a selectively breaking display lamp 22. An operating state is confirmed by a monitoring instrument 30. Thus, a selective breaking circuit is formed of a trip block switch. When the number of circuits is increased, an operator can judge the lamp, and hence an overload prevention of the facility can be effectively decided.
