Automatic alarm fire extinguishing system for high-voltage hollow reactor

Abstract

The embodiment of the invention discloses an automatic alarm fire extinguishing system for a high-voltage hollow reactor. The reactor comprises a reactor body, a supporting frame is arranged in the hollow position inside the reactor body, a cooling water pipe is wound on the supporting frame, a plurality of spraying structures are arranged on the cooling water pipe, the spraying structures are connected with the cooling water pipe through a control valve, the control valve comprises a shell and an electromagnetic module, a manual module and a temperature control module which are connected withthe shell, a temperature detection unit is arranged on the reactor body, the temperature detection unit is electrically connected with a control loop, and the electromagnetic module is electrically connected with the control loop. According to the system, the temperature of the reactor is monitored in real time through the temperature detection unit arranged in the reactor body and the temperature information is fed back to the control circuit, and when the temperature is higher than the set value, the spraying structures are controlled through the control circuit to help the reactor to perform automatic cooling and fire extinguishing.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of fire protection, in particular to an automatic alarm and fire extinguishing system for a high-voltage air-core reactor. Background technique [0002] High-voltage air-core reactors are inductive high-voltage electrical appliances used in power systems to limit short-circuit currents, reactive power compensation, and phase shifting. Since the magnetic flux forms a loop through the air, it is called an air-core reactor. Air-core reactors are mainly divided into air-core series reactors, air-core filter reactors, air-core shunt reactors, air-core current-limiting reactors, air-core split reactors, air-core starting reactors, etc., which are often used for reactive power compensation, harmonic filtering, and current limiting. and other occasions. [0003] Because the high-voltage air-core reactor has the advantages of low noise, good inductance linearity, and can be installed outdo...

Problems solved by technology

[0004] To this end, the embodiment of the present invention provides an automatic alarm and fire extinguishing system for high-voltage air-core reactors. The temperature of the reactor is monitored in real time through the temperature detection unit installed in the reactor body and fed back to the control circuit. When the temperature is higher than the set When the value is high, the control circuit controls the spray structure to help the reactor to cool down and extinguish the fire, so as to solve the problem in the prior art that the reactor is prone to high-temperature fire hazards due to the difficulty in detecting the temperature inside the reactor body
