Abstract

The utility model discloses a low-voltage switch cabinet which comprises a cabinet body and a busbar chamber, a cable chamber and an electrical component chamber (a functional unit chamber) which are arranged in the cabinet body. The busbar chamber is positioned at the rear part of the cabinet body; the cable chamber is positioned at the right front part of the cabinet body; the cable chamber is provided with a cable connector insulation suite and a cable climbing fixing support; the electrical component chamber is positioned at the left front part of the cabinet body; the electrical component chamber is provided with a drawer; the drawer is provided with an electrical mechanical interlocking device which is provided with four positions for operation, testing, drawing out and isolation; a functional plate is arranged between the busbar chamber and the electrical component chamber; and a branch bus is embedded in the function plate. The drawer type low-voltage switch cabinet has a compact structure and strong universality, is flexible to assemble and has high safety performance; in the process that the drawer is repeatedly pulled out or pushed in, safety production accidents such as short circuit and electric leakage can be prevented, so that the service life of equipment is prolonged, and personal safety of an operator is improved.

Description

A kind of drawer type low voltage switch cabinet
Technical field
The utility model relates to a kind of low-tension switch cabinet, particularly a kind of drawer type low voltage switch cabinet.
Background technology
Current manufacturing enterprise and power supply management all need to use a large amount of switch cubicles or control cabinet, existing drawer type low voltage switch cabinet is because can hold more functional unit with smaller space, and due to structure highly versatile, assemble the feature such as flexible and obtained wide model application, but in use and maintenance process, in the situation that main circuit is charged, the operation such as drawer function unit need to often be performed extraction, push, how to ensure the fail safe of operating process, do not produce the safety problem such as short circuit, electric leakage particularly important.
Utility model content
The purpose of this utility model is to provide a kind of compact conformation, highly versatile, assembling is flexible and security performance is high drawer type low voltage switch cabinet, drawer by the process of repeatedly extracting out or pushing in, prevent that the industrial accident such as short circuit, electric leakage from occurring, also improve operating personnel's personal safety extension device useful life.
It is as follows that the utility model solves the problems of the technologies described above adopted technical scheme: a kind of drawer type low voltage switch cabinet, comprise cabinet and be arranged on bus-bar room, cable vault and the electric elements chamber (functional unit chamber) in cabinet, described bus-bar room is positioned at cabinet rear, described cable vault is positioned at cabinet right front, described electric elements chamber is positioned at cabinet left front, described electric elements chamber arranges multiple drawers, described drawer arranges electricapparatus interlock, between described bus-bar room and electric elements chamber, feature board is set.
The components and parts such as circuit breaker, current transformer, contactor, relay are installed in described drawer;
Described drawer outer setting operating grip;
Metal division board with wind hole is set between described drawer;
Described electricapparatus interlock arranges operation, test, extracts out and four positions of isolation;
Described feature board adopts high-strength anti-flaming and has the environment-friendly materials of arc-suppression function, and or not containing CFC and halogen, feature board inside is not embedded with branch bar;
The connector that blocks branch bar is set on described drawer;
Described cable vault arranges cable joint insulation external member and cable is sought connections with fixed support;
Upper end, described cabinet front and lower end are provided with ventilating window.
Operation principle: in order to prevent drawer box circuit breaker mis-operation, drawer unit is provided with reliable electricapparatus interlock, by operating grip control, when drawer inserts or interlock while not forwarding closing position to completely, circuit breaker can not close a floodgate; When drawer inserts completely, operating grip rotates to after closing position, and circuit breaker could close a floodgate; When after breaker open operation, operating grip just can forward withdrawn position to, and drawer could be extracted out; When in isolated location, drawer main contact patches isolated, and drawer can not insert and can not extract out simultaneously.Feature board is for being once connected between drawer and bus-bar room, possesses isolation features simultaneously,, feature board inside is embedded with branch bar, and it is not outer naked that branch bar lies in inside, when circuit units is safeguarded, drawer can be extracted out to cabinet and carry out outward, because the branch bar of drawer positions is not outer naked, can effectively prevent the contact of human body, in the time that drawer inserts, the connector on drawer can block branch bar.
Beneficial effect: the utility model is simple and reasonable, holds more functional unit with less space, and flexibly, and security performance is high for structure highly versatile, assembling.Electricapparatus interlock can ensure also can safely drawer be extracted out or be inserted the in the situation that of major loop band point, thereby components and parts in drawer and major loop are disconnected or connected; Between bus-bar room and electric elements chamber, feature board is set, can effectively prevent the accident that between arcing that switch element causes because of fault and bus, short circuit causes, tight quarantine measures are taked, simultaneously because the branch bar of drawer positions is not outer naked, in the time extracting drawer out, can effectively prevent the electric shock of human body, prevent that security incident from occurring, and improves operating personnel's personal safety extension device useful life.
