Abstract
The utility model relates to a stationary type metal switch cabinet which comprises a cabinet body and two cabinet doors connected with the cabinet body. The cabinet body comprises a breaker chamber, a busbar chamber, a cable chamber and a relay chamber, wherein the chambers are separated by steel plates.
Description
Technical field
The utility model relates to the electric power application, particularly relates to a kind of fixed metal switch cabinet.
Background technology
In the power industry field, switch cubicle is divided into open type and closed two classes, and for enclosed switchgear, except having waterproof and the performance such as dustproof, the particular importance that aspect the good heat radiation that guarantees switch cubicle, just shows, not only to reasonably select selecting with radiating mode of radiator in this respect, also extremely important to the layout of switch cubicle.While, what existing switch cubicle just showed when carrying out equipment installation and maintenance was very inconvenient owing to the characteristic of enclosed switchgear.
The inventor is by the many years of experience in this area, existing enclosed switchgear is proposed an improvement technology, so that adopt the switch cubicle of the technical program can not only be adapted to the installation and maintenance of equipment, also so that layout is more reasonable, whole line clear and the space sense of the switch cubicle after having guaranteed to use are obvious simultaneously.
The utility model content
The purpose of this utility model is the improvement technology that proposes a kind of fixed metal switch cabinet, when making things convenient for the equipment installation and maintenance, guarantees the line clear in the switch cubicle, is beneficial to the management to the circuit in the switch cubicle.
The utility model is achieved through the following technical solutions:
Fixed metal switch cabinet includes cabinet, and with the cabinet door that cabinet is connected, described cabinet door has two to be front rear cabinet door; Described cabinet includes breaker chamber, bus-bar room, and the cable vault, relay bungalow separates with steel plate between described each chamber;
Described breaker chamber is in the front bottom of cabinet, and circuit breaker is connected with operating mechanism by pull bar, and the upper connecting terminal of described circuit breaker is connected with upper isolating switch, and the lower connecting terminal of circuit breaker is connected with current transformer, and described breaker chamber also is provided with pressure relief channels;
Described bus-bar room is in the cabinet upper back, and bus is product shape to be arranged, and bus is connected with upper isolating switch binding post;
Described cable vault is at the rear of cabinet bottom; Described relay bungalow has the terminal board support in the place ahead, cabinet top in the described relay bungalow.
The operating mechanism of described circuit breaker is in positive left position, and its top is the operation interlocking mechanism of isolating switch.
Be provided with voltage monitoring device in the described cable vault.
Also include mechanical interlocks in the described cabinet.
The beneficial effects of the utility model are:
By the technical program, can be implemented in when making things convenient for the equipment installation and maintenance, guarantee the line clear in the switch cubicle, be beneficial to the management to the circuit in the switch cubicle.

Embodiment
Below in conjunction with accompanying drawing concrete mode of the present utility model is elaborated, embodiment of the present utility model is exemplary, only can not be interpreted as it is to restriction of the present utility model for explaining content of the present utility model.
The utility model is achieved through the following technical solutions:
With reference to the accompanying drawings 1 and shown in Figure 2, fixed metal switch cabinet includes cabinet 1, and with the cabinet door that cabinet is connected, described cabinet door has two front cabinet doors 2 and rear cabinet door; Described cabinet includes breaker chamber 4, bus-bar room 5, and cable vault 6, relay bungalow 3 separates with steel plate between described each chamber;
Described breaker chamber is in the front bottom of cabinet, and circuit breaker is connected with operating mechanism by pull bar, and the upper connecting terminal of described circuit breaker is connected with upper isolating switch, and the lower connecting terminal of circuit breaker is connected with current transformer, and described breaker chamber also is provided with pressure relief channels; If when internal arc occured, gas can be by the exhaust passage with earth pressure release.
Described bus-bar room is in the cabinet upper back, and in order to reduce the height of cabinet, bus is product shape to be arranged, and with the high porcelain insulating supporting of bending strength, the bending strength of selecting in the present embodiment is more than the 7000N, and bus is connected with upper isolating switch binding post; Can isolate setting between adjacent two cabinet bus-bar rooms.
Described cable vault is at the rear of cabinet bottom; Be provided with voltage monitoring device in the described cable vault, cable is fixed on the support, and when being the contact scheme for main electrical scheme, this chamber is the link cable chamber.Described relay bungalow has the terminal board support in the place ahead, cabinet top in the described relay bungalow; Men Shangke installs the secondary components such as indicating instrument, signal element, and the little bus of secondary also can be arranged in the relay bungalow top.
Also include mechanical interlocks in the described cabinet; In order to prevent on-load deciliter isolating switch, prevent that a minute mistake is closed circuit breaker by mistake, prevent mistakenly entering charged chamber, prevent charged splice grafting ground switch, prevent mistake crossed belt grounding switch, switch cubicle adopts corresponding mechanical interlocking.
The operating mechanism of described circuit breaker is in positive left position, and its top is the operation interlocking mechanism of isolating switch.
Described above is implementation technical scheme of the present utility model and operation principle, and those skilled in the art improves according to the technical program certainly, and this improvement still belongs to the protection range of the technical program.
