12kV current-carrying 1250A solid insulation combined switch cabinet

Abstract

The invention discloses a 12kV current-carrying 1250A solid insulation combined switch cabinet. The combined switch cabinet comprises a cabinet body, wherein a cabinet door is arranged on the front surface of the cabinet body and hinged with the cabinet body, an observing window is fixed on the front surface of the upper end of the cabinet door, radiating holes are formed in the front surface of the lower end of the cabinet door, and a second dustproof net is arranged in each radiating hole; a card reader is arranged on the front surface of the cabinet door, and an intelligent electronic lockis arranged on the inner surface wall of the cabinet door; the card reader reads IC card information, the IC card information is recognized by a controller, the intelligent electronic lock is unlockedif the recognition passes, the complicated procedures for unlocking are reduced, and unlocking is simpler and more convenient, so that the solid insulation combined switch cabinet is more convenientto use; temperature sensors are arranged on the inner surface wall of the cabinet body, when the temperature reaches the set temperature of the controller, a cooling fan is started, and the inside ofthe cabinet body is cooled; when the temperature is lower than the set temperature of the controller, a cooling fan is stopped, operation of the cooling fan is accurately controlled, and energy consumption is reduced.

Description

technical field [0001] The invention belongs to the technical field of electric power equipment, and in particular relates to a 12kV current-carrying 1250A solid insulation combined switchgear. Background technique [0002] Solid insulation combined switchgear is a combination of three technologies including insulated busbar, combined unit miniaturization and external solid sealing. It is a new type of power distribution equipment that is mainly insulated from body to ground and phase to phase, and the conductive or semi-conductive shielding layer on its outer surface is reliably grounded. It is generally used by the State Grid and China Southern Power Grid. [0003] The operation of the original solid insulated combined switchgear is cumbersome to unlock, which reduces the convenience of using the solid insulated combined switchgear, and it is difficult to turn on or off the cooling fan according to the internal temperature, resulting in high energy consumption.
