An operation monitoring and protection device for sulfur hexafluoride power distribution room

Abstract

The invention provides an operation monitoring protective device for a sulfur hexafluoride power distribution room. According to the operation monitoring protective device, a solar panel, a lighting device, an oxygen content sensor, a control device, a temperature controller, a detecting assembly, a cooling fan, an electricity storage device, a sulfur hexafluoride sensing module and a carbon monoxide detecting module are arranged on the outer surface of a shell, wherein the sulfur hexafluoride sensing module is used for sensing the concentration of sulfur hexafluoride in the environment, and transmitting the sensed concentration of sulfur hexafluoride to the control device; when any one of the concentration of sulfur hexafluoride, the amount of carbon monoxide, the amount of smoke, the amount of strong light, the amount of the temperature and the water content exceeds a prewarning value, the control device controls an alarm Lc to send out alarming sounds for reminding a user that the current environment is in the early warning state, meanwhile, the control device transmits the condition that the amount of smoke, the amount of strong light, the amount of temperature and the water content exceed the preset value to an upper computer through a wireless communication device, so that the manager of the upper computer can know the information of the environmental condition inside the power distribution room in real time, then the manager makes the correct conduction in time, and finally, the personnel security is protected.

Description

technical field [0001] The invention relates to the field of electric power safety, in particular to an operation monitoring and protection device for a sulfur hexafluoride power distribution room. Background technique [0002] Sulfur hexafluoride (SF6) has good electrical insulation performance and excellent arc extinguishing performance. Its electric strength is 2.5 times that of nitrogen under the same pressure, its breakdown voltage is 2.5 times that of air, and its arc extinguishing ability is 100 times that of air. , is a new generation of ultra-high voltage insulating dielectric material superior to that between air and oil. Sulfur hexafluoride is widely used in circuit breakers, high-voltage transformers, gas-enclosed combined capacitors, high-voltage transmission lines, transformers, etc. due to its good insulation performance and arc-extinguishing performance. Of the approximately 8500t of sulfur hexafluoride (SF6) gas produced globally each year, more than half i...

Problems solved by technology

[0003] In the prior art, only one item of environmental factors can be tested during the maintenance of the power distribution room, so that the staff cannot complete the detection and confirmation of all environmental factors in the power distribution room at the same time during the maintenance, resulting in hidden dangers in safety issues

On the other hand, the above-mentioned individual detection uses a lot of equipment, which is inconvenient to carry on the body and affects the operation. Moreover, multiple detection devices cannot coordinate detection, which will lead to the negligence of maintenance personnel and lead to accidents.
