Handcart type high-voltage outgoing line cabinet

Abstract

The invention discloses a handcart type high-voltage outgoing line cabinet. The cabinet comprises a cabinet body, and a handcart chamber is fixedly arranged at the bottom of the front surface in the cabinet body; a handcart fixing block is fixedly connected to the bottom of the inner back surface of the handcart chamber; the cabinet body is fixedly connected with a handcart through a handcart fixing block; the handcart comprises a handcart base, two sliding plates and two circuit breaker mounting boxes; the two sliding plates are slidably connected to the two sides of the top end of the handcart base correspondingly; the two circuit breaker mounting boxes are fixedly connected to the top ends of the two sliding plates respectively; the back surfaces of the handcart base are provided with connecting grooves, the top portion of the back surface of the cabinet is fixedly connected with a first maintenance cover through screws, the bottom portion of the back surface of the cabinet body isfixedly connected with a second maintenance cover through screws. According to the invention, by arranging the whole structure, the maintenance of the internal structure of the cabinet body is facilitated; and by arranging the handcart structure, the space is reasonably utilized to improve the voltage conversion efficiency, and the maintenance of the circuit breaker is facilitated.

Description

technical field [0001] The invention relates to a high-voltage outlet cabinet, in particular to a handcart-type high-voltage outlet cabinet, which belongs to the technical field of high-voltage switch cabinets. Background technique [0002] High-voltage switches refer to electrical products used in power system power generation, transmission, distribution, power conversion and consumption for on-off, control or protection, with a voltage level of 3.6kV-550kV, mainly including high-voltage circuit breakers and high-voltage isolating switches And grounding switch, high-voltage load switch, high-voltage automatic recloser and sectionalizer, high-voltage operating mechanism, high-voltage explosion-proof power distribution device and high-voltage switchgear and other major categories. [0003] The existing handcart-type high-voltage outlet cabinet can only be used for one loop outlet. AC metal-enclosed switchgear is widely used in power plants, power systems, and petrochemical, m...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a handcart-type high-voltage outlet cabinet to solve the problem that the existing handcart-type high-voltage outlet cabinet proposed in the above background technology can only be used for one loop outlet, and AC metal-enclosed switchgear is widely used in power plants, Power systems, petrochemical, metallurgical and other industrial and mining enterprises and electrification systems, etc. In these occasions, the space of power distribution rooms in some places is small, which cannot meet the requirements of capacity expansion and expansion, and it is inconvenient to pull out and fix the handcart, which is not conducive to the maintenance work.
