摘要： PURPOSE:To discover the generation of a flame without fail, to activate a fire extinguishing device and to obtain the using quantity of fire extinguishing agent as necessary and sufficient quantity by using the plural number of the filters of the wave length of the resonance radiating of the flame and the near wave length, detecting respective radiation intensity and calculating the relation between them. CONSTITUTION:As a flame sensor 9 sensor is used to detect plural numbers of spectrums to include a selective radiation spectrum emitted from the flame of a medium infrared band and a means is provide to calculate the intensity ratio of the spectrum. A fire extinguishing is known from the calculated result, the temperature of the extinguished subject can be calculated from the intensity of a gray radiation and this is interlocked with an automatic fire extinguishing device. Thus, the automatic fire extinguishing is possible and simultaneously, it is cleared whether the subject goes down to an ignition temperature or not. Since the consumption of the fire extinguishing agent can be suppressed to the necessary and sufficient quantity, the fire extinguishing agent can be prevented from being wasted and a secondary damage can be limited to a minimum.

摘要： PROBLEM TO BE SOLVED: To continuously grasp the contamination of an actual insulator with high accuracy by correcting the estimated contamination of the actual insulator obtained from meteorological data by calculation with the measured contamination value and the estimated contamination obtained from meteorological data by calculation of a pilot insulator. SOLUTION: The contamination of a pilot insulator 5 is measured at prescribed intervals by a washing type contamination measuring means 4. The estimated contamination of an actual insulator 10 and a pilot insulator 5 are calculated by an arithmetic means 6 from the meteorological data of a meteorological data observing means 1 having an anemometer 2 and a rain gauge 3. The actual insulator contamination is estimated by the arithmetic means 6 from these values based on the following equation:(the contamination of the actual insulator 10)=(the estimated contamination of the actual insulator 10 obtained from meteorological data by calculation)+(the measured contamination of the pilot insulator 5)-(the estimated contamination of the pilot insulator 5 obtained from meteorological data by calculation). The added quantity of insulator contamination has no relation with the existing stuck quantity, and the decrease of the contamination due to a rainfall is calculated when the existing stuck quantity is multiplied by a certain ratio.

摘要： PURPOSE:To accurately and automatically detect abnormality in an insulator- washing device so as to notify a control station of the abnormality by storing a secular change in each of flow signal into a flowmeter joined to the primary side a pump or to the secondary side thereof, and then connecting an arithmetic processing device which finds an abnormal flow change to the flowmeter. CONSTITUTION:A flowmeter 14 is joined to the secondary side of the main valve 5 of a pump 2 to detect a flow signal on the amount of water flowing through this secondary-side part during operation of an insulator-cleaning device. The flow signal extracted from the flowmeter 14 is then inputted into an arithmetic processing device 15 attached to a control board 10. This arithmetic processing device 15 stores a secular change in each of flow signal extracted from the flowmeter 14 while enclosing a program for finding an abnormal flow change and automatically transmitting a signal indicating abnormality, given out when the abnormality is acknowledged, to a control station to make a request for repair and inspection of the device. Thus, abnormality can surely be detected to automatically notify the control station of the abnormality.

CONSTITUTION:The fire detection signal of a fire sensor 1 is inputted to a camera switch part 3 and an ITV camera 2, which is activated by a signal from the camera switch part 3, photographs the picture of a designated area. A still picture transmission part 4 processes the photographic picture, which is photographed by the ITV camera 2, to a still picture and transmits the still picture. In the manned monitoring spot, a still picture reception part 5 is set to receive the still picture, which is transmitted from the still picture transmission part 4 through a transmission line 7, and a display device 6 is set to display the still picture. Then, the still picture reception part 5 processes the transmitted still picture signal and restores the signal to the picture. Then, the picture is displayed on a display 7 and a warning is outputted. Thus, it is not necessary to go to a fire generation place each time and to confirm the generation of the fire. Then, a countermeasure can be easily and speedily executed to the fire.

摘要： PROBLEM TO BE SOLVED: To provide a snow-melting device which is low in cost, easy in execution on an existing house, and capable of surely demonstrating the snow-melting effect. SOLUTION: A large number of pipe heaters 2 extending in the vertical direction of a roof are mounted on frames 1 with specified intervals, and the frames are installed on an upper surface of a roof member at an eaves part (and a ridge part). Snow is cut in a specified width, and dropped from the eaves. Since the whole snow need not be melted, the electricity charges are small, the weight of a snow-melting device is light in weight, and easy in installation on an existing house.
