Abstract

The present invention discloses a high-voltage switch cabinet remote monitoring device and a high-voltage switch. The high-voltage switch cabinet remote monitoring device comprises a high-voltage switch cabinet body and a temperature measuring system arranged on the high-voltage switch cabinet body, a fixing frame, a smoke sensor and a humidity sensor are separately arranged in the high-voltage switch cabinet body, and a high-voltage isolation switch is arranged at the upper end of the fixing frame; a fan, a heating box and a main electric push rod are separately arranged on the outer wall of the high-voltage switch cabinet body, the air outlet end of the heating box is connected with an exhaust pipe, and the exhaust pipe is communicated with a branch air pipe; the air outlet end of the branch air pipe is arranged at one side of the high-voltage isolation switch, a frame groove is formed in the front of the high-voltage switch cabinet body, a fireproof cover is inserted into the frame groove, and the telescopic end of the main electric push rod is arranged on the fireproof cover. If a fire occurs, an auxiliary electric push rod indirectly pushes a disconnecting link on the high-voltage isolation switch to be separated through a push rod to cut off power, then the fireproof cover is moved out through the main electric push rod, if heating is abnormal, the fan exhausts cooling air from the branch air pipe, so that ventilation and heat dissipation are carried out on a contact position in the high-voltage switch cabinet body, and the effective emergency treatment is carried out.

Description

technical field

[0001] The invention belongs to the technical field of switchgear, and in particular relates to a remote monitoring device for a high-voltage switchgear and a high-voltage switchgear Background technique

[0002] High-voltage switchgear refers to the role of on-off, control or protection in power system power generation, transmission, distribution, power conversion and consumption.

[0003] During the operation of the high-voltage switchgear, the contacts of the switch, the busbar connector and other parts will cause excessive contact resistance and heat due to long-term heavy load, aging, and high moisture. Due to the closed operation of the switchgear, the small internal space and the insulation For protection and other reasons, the temperature of these heating parts can hardly be monitored in the running state, which may eventually cause fires and large-scale power outages due to overheating. Therefore, it is necessary to set up a temperature measurement s...
