Description

Armored withdraw type metal enclosed switch cabinet

【Technical field】

The utility model is related to power-supply device field, and in particular to a kind of armored withdraw type metal enclosed switch cabinet.

【Background technology】

Switch cubicle is a kind of electrical equipment, and switch cubicle outside line is introduced into master switch in cabinet, is switched subsequently into sub-control, respectively Branch is needed to set by it.Such as instrument, automatic control, motor magnetic switch, various A.C. contactors etc., have also set hyperbaric chamber with Low-pressure chamber switch cubicle, is provided with high voltage bus, such as power plant, and what is had is additionally provided with to protect the low-frequency load reduction of capital equipment.

The handcart circuit breaker ground connection of prior art switch cubicle passes through earth resistance, the structural reliability and company with cabinet ground connection Continuous property is low, and there is certain potential safety hazard.

Therefore, it is necessary to provide a kind of new armored withdraw type metal enclosed switch cabinet.

【Utility model content】

The purpose of this utility model is to provide a kind of reliability and continuity for increasing ground connection, reduces the armouring of earth resistance Withdraw type metal enclosed switch cabinet.

The technical solution of the utility model is as follows：A kind of armored withdraw type metal enclosed switch cabinet, including it is empty with housing Between cabinet and the receiving space is divided into the dividing plate of cable vault, bus-bar room and breaker chamber, be provided with the cable vault Earthed switch, earth bus, moving contact and static contact, are provided with breaker in the breaker chamber, the breaker is by described Earthed switch is crimped with the moving contact and the static contact, and the moving contact and the static contact with the earth bus It is electrically connected with.

Preferably, also it is electrically connected with including the arrester located at the cable vault, the arrester and the earth bus.

Preferably, also including the movable operation handle for opening and closing the earthed switch, the moving contact sets In the movable operation handle.

Preferably, transformer is provided with the bus-bar room, the transformer and the earth bus are electrically connected by wire Connect.

Preferably, high-tension cable is additionally provided with the cable vault, the high-tension cable and the earth bus are electrically connected with.

Preferably, two armored withdraw type metal enclosed switch cabinets being disposed adjacent electrically are connected by the earth bus Connect.

Preferably, the earth bus is 60X4 copper busbars.

The beneficial effects of the utility model are：The armored withdraw type metal enclosed switch cabinet that the utility model is provided passes through Earth bus is set, and breaker, arrester, transformer, high-tension cable and the earth bus are electrically connected with, reduce The setting of earth resistance, increases the reliability and continuity of ground connection, and improves certain security performance.

【Brief description of the drawings】

Fig. 1 is the structure chart of the utility model armored withdraw type metal enclosed switch cabinet.

【Specific embodiment】

The utility model is described in further detail with implementation method below in conjunction with the accompanying drawings.

Fig. 1 is referred to, is the structure chart of the utility model armored withdraw type metal enclosed switch cabinet.The armored withdraw type Metal closed switch cabinet 100 includes the cabinet 1 with receiving space and the receiving space is divided into cable vault 11, bus-bar room 12 and the dividing plate 2 of breaker chamber 13.

It is provided with the cable vault 11 and is fixedly arranged on the arrester 111 of the bottom of the cabinet 1, the ground connection located at the dividing plate 2 Switch 112, the earth bus 113 being distributed in the cable vault 11, moving contact 114, static contact 115, high-tension cable 116 and use In the movable operation handle 117 for opening and closing the earthed switch 112；The arrester 111 and the earth bus 113 It is electrically connected with；The moving contact 114 is located at the movable operation handle 117, is carried out using the movable operation handle 117 Breaking-closing operating；The high-tension cable 116 and the earth bus 113 are electrically connected with.

Be provided with breaker 131 in the breaker chamber 13, the breaker 131 by the earthed switch 112 with it is described Moving contact 114 and the static contact 115 are crimped, and the moving contact 114 and the static contact 115 with the earth bus 113 are electrically connected with.

Transformer 121 is provided with the bus-bar room 12, the transformer 121 and the earth bus 113 pass through wire 122 It is electrically connected with.

In the present embodiment, two armored withdraw type metal enclosed switch cabinets 100 being disposed adjacent pass through the ground connection Bus 113 is electrically connected with；The earth bus 113 is 60X4 copper busbars.

The beneficial effects of the utility model are：The armored withdraw type metal enclosed switch cabinet 100 that the utility model is provided It is by setting earth bus 113 and breaker 131, arrester 111, transformer 121, high-tension cable 116 and the ground connection is female Line 113 is electrically connected with, and reduces the setting of earth resistance, increases the reliability and continuity of ground connection, and improves certain safety Performance.

Above-described is only implementation method of the present utility model, it should be noted here that for the ordinary skill of this area For personnel, on the premise of the utility model creation design is not departed from, improvement can also be made, but these belong to this practicality New protection domain.
