Improved high-voltage power distribution cabinet structure

Abstract

The present invention discloses an improved high-voltage power distribution cabinet structure. The structure comprises a power distribution cabinet body, and a cabinet cavity body is arranged in the power distribution cabinet body; a bus cavity is arranged at the top of the cabinet cavity body, a horizontal main bus is arranged, a branch bus is arranged at the lower end of the main bus, and a switch cavity is arranged at the lower end of the bus cavity; an upper portion isolation switch and a lower portion isolation switch are arranged in a switch cavity, a vacuum circuit breaker is connected and arranged between the upper portion isolation switch and the lower portion isolation switch; the upper portion isolation switch is connected with a current transformer, and a voltage transformer is connected with the lower portion isolation switch; and a cable cavity is arranged at the lower end of the switch cavity, and an instrument cavity is arranged at the right side of the bus cavity. The improved high-voltage power distribution cabinet structure is convenient in maintenance and easy to monitor the temperature in the cabinet.

Description

technical field [0001] The invention relates to the field of electric power equipment, in particular to an improved structure of a high-voltage power distribution cabinet. Background technique [0002] High-voltage power distribution cabinets are more and more widely used in factories and living areas to achieve power conversion, distribution, and control functions. The existing power distribution cabinets have low protection safety factors and short service life. Users' demand for electric energy is increasing. Power distribution cabinets The capacity of the power distribution cabinet is increasing year by year. If an accident occurs in the power distribution cabinet, the consequences will be serious. The existing power distribution cabinets are fixed by screws, and the rear door is easy to open by mistake. All copper row cables are high voltage, which has hidden dangers. The maintenance and repair of the power distribution cabinet is troublesome. If the temperature in the ...

Problems solved by technology

[0002] High-voltage power distribution cabinets are more and more widely used in factories and living areas to achieve power conversion, distribution, and control functions. The existing power distribution cabinets have low protection safety factors and short service life. Users' demand for electric energy is increasing. Power distribution cabinets The capacity of the power distribution cabinet is increasing year by year. If an accident occurs in the power distribution cabinet, the consequences will be serious. The existing power distribution cabinets are fixed by screws, and the rear door is easy to open by mistake. All copper row cables are high voltage, which has hidden dangers. The maintenance and repair of the power distribution cabinet is troublesome. If the temperature in the cabinet is too high, it will affect the use of electrical appliances in the equipment, and the outdoor high-voltage power distribution cabinet is often eroded by rain and rain, and the operation of the vacuum circuit breaker is troublesome.
