Abstract
The utility model relates to switching equipment in an urban mass transit direct-current traction power supply system, in particular to intelligent safety protection type direct-current traction power supply switching equipment. The intelligent safety protection type direct-current traction power supply switching equipment comprises a cabinet body, an isolation switch and a bus, wherein the isolation switch and the bus are arranged in the cabinet body. The intelligent safety protection type direct-current traction power supply switching equipment further comprises a breaker handcart capable of being moved out of the cabinet body. A low-voltage chamber is arranged at the upper front part of the cabinet body; a low-voltage control element is mounted in the low-voltage chamber; a breaker chamber is arranged at the lower front part of the cabinet body, so that the breaker handcart can enter and exit the breaker chamber; a bus chamber is arranged at the rear part of the cabinet body; and an isolation switch and a wire inlet bus are mounted in the bus chamber. According to the intelligent safety protection type direct-current traction power supply switching equipment, the low-voltage control element is mounted in the cabinet body and is mounted with the breaker handcart in a separated manner. Primary elements and secondary elements are not mutually influenced so that the intelligent safety protection type direct-current traction power supply switching equipment is convenient to mount and maintain and has high operation reliability. Meanwhile, the weight of the breaker handcart is reduced, so that the breaker handcart is conveniently moved into or out of the cabinet body. High-voltage elements and low-voltage elements are arranged in the separated manner, so that the intelligent safety protection type direct-current traction power supply switching equipment facilitates the standardized design of an element module, and is good for reducing the manufacturing cost.
Description
Technical field
The utility model relates to a kind of switchgear that is used for the urban track traffic DC traction power-supply system, particularly a kind of intelligent safety protection type direct-current traction power supply switchgear that adopts handcart type breaker.
Background technology
In the urban track traffic DC traction power-supply system, the direct-current traction power supply switch cabinet of handcart-type is made up of bus, low voltage control element etc. in circuit breaker cart, isolating switch, the cabinet usually.In the traditional structure, the low voltage control element that is used for functions such as wireline inspection, protection is installed in circuit breaker cart usually, has increased handcart weight, is not easy to moving of handcart; And when the maintenance low voltage component, also need whole handcart be pulled out cabinet, because the installation of low voltage component and circuit breaker components influences each other, make its maintenance very inconvenient simultaneously; In addition,, be unfavorable for the standardized designs of high voltage component and low pressure parts, improved manufacturing cost owing to low-voltage module and the integrated installation of circuit breaker cart.
Summary of the invention
The utility model technical problem to be solved is, provide a kind of rationally distributed, functional module influence each other little, install and maintenance is convenient, the intelligent safety protection type direct-current traction power supply switchgear of low cost of manufacture.
The intelligent safety protection type direct-current traction power supply switchgear of the utility model includes a cabinet and the isolating switch and the cabinet bus that are positioned at cabinet, also includes the circuit breaker cart of extensible cabinet; Said cabinet front upper part is provided with low-pressure chamber, and the low voltage control element is installed in the low-pressure chamber; The preceding bottom of cabinet is a breaker chamber, supply circuit breaker cart into and out of; The cabinet rear portion is a bus-bar room, and isolating switch and inlet wire bus are installed in the bus-bar room.
The utility model is installed in the low voltage control element in the cabinet, separates installation with circuit breaker cart, once and between the secondary component does not influence each other, and it is convenient to install and overhaul, and operational reliability is high; Alleviate the weight of circuit breaker cart simultaneously, made things convenient for its shift-in and the operation of shifting out cabinet; The separation setting of high and low pressure element has made things convenient for the standardized designs of component module, helps reducing manufacturing cost.
