Abstract
A drawer-type lightning arrester cabinet comprises a bus-bar room, a cable chamber, a shutter mechanism arranged between the bus-bar room and the cable chamber and a lightning arrester handcart which can slidingly move in and out on a base plate of the shutter mechanism. The lightning arrester handcart comprises a handcart body, three moving contacts installed on the front end of the handcart body and wheels disposed on the bottom of the handcart body. The shutter mechanism comprises a separator plate with three static contacts and the base plate connected with the bottom of the separator plate. After the lightning arrester handcart slides to the operating position on the base plate, the three moving contacts are respectively inserted into the three static contacts. A three-phase cable of a lightning arrester is connected with a three-phase bus through the moving and static contacts. According to the utility model, the lightning arrester is installed on the push-in lightning arrester handcart and the lightning arrester is pushed to the operating position by the handcart. Thus, overhauling and maintenance of the lightning arrester are realized without power cut of a switch cabinet. The drawer-type lightning arrester cabinet provided by the utility model has good safety and high reliability, and can be adopted to guarantee safe and stable power supply of a factory and reduce personal injury caused by deficient isolation.
Description
Technical field
The utility model relates to a kind of lightning arrester cabinet, especially a kind of drawer type lightning arrester cabinet.
Background technology
At present, in the high-tension switch cabinet of using on market, lightning arrester generally is arranged in cable vault, directly is connected with bus.When lightning arrester needs repair and maintenance, this switch cubicle overall isolation often must be caused to the isolation extension, affect the security and stability of Factory Electricity Supply; If isolate, not in placely also will cause the loss of life or personal injury event.
Summary of the invention
The purpose of this utility model is for the existing security hidden trouble of lightning arrester repair and maintenance in high-tension switch cabinet, proposes the drawer type lightning arrester cabinet that a kind of isolation that do not need to have a power failure can repair and maintenance.
The technical solution of the utility model is:
A kind of drawer type lightning arrester cabinet, comprise bus-bar room and cable vault, it also comprises the valve mechanism be arranged between bus-bar room and cable vault and can on the base plate of valve mechanism, slide the arrester handcart of turnover, described arrester handcart is for placing lightning arrester, comprise car body, be arranged on three moving contacts of car body front end and be located at the roller of vehicle bottom, described moving contact is connected with lightning arrester, described valve mechanism comprises with the dividing plate of three fixed contacts and the base plate that is connected with dividing plate bottom, described arrester handcart is after sliding into service position on base plate, three moving contacts insert respectively three fixed contacts, the threephase cable of lightning arrester is by moving, fixed contact is connected with the three-phase bus in bus-bar room.
On the car body of arrester handcart of the present utility model, be with jug.
Lightning arrester of the present utility model is high-voltage arrester.
Valve mechanism of the present utility model also comprises the cover plate that can cover fixed contact.
The both sides of base plate of the present utility model are provided with the guide rail into the arrester handcart slide-and-guide.
The beneficial effects of the utility model:
The utility model adopts the handcart principle, being about to lightning arrester is arranged on the push-in type arrester handcart, by handcart, lightning arrester is pushed and releases service position, thereby realize under power-off condition, lightning arrester not being carried out to repair and maintenance at switch cubicle, fail safe is good, reliability is high, can guarantee the safety and stability of Factory Electricity Supply, reduces the isolation loss of life or personal injury event caused not in place.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of arrester handcart of the present utility model.
Fig. 3 is the structural representation of valve mechanism of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
As shown in Figure 1, a kind of drawer type lightning arrester cabinet, comprise bus-bar room 4 and cable vault 3, it also comprises the valve mechanism 2 be arranged between bus-bar room 4 and cable vault 3 and the arrester handcart 1 that can above slide at the base plate 2-3 of valve mechanism (2) turnover, described arrester handcart 1 is be used to placing lightning arrester, comprise car body 1-1, be arranged on three moving contact 1-2 of car body front end and be located at the roller 1-3 of vehicle bottom, described moving contact 1-2 is connected with lightning arrester, described valve mechanism 2 comprises with the dividing plate 2-1 of three fixed contact 2-2 and the base plate 2-3 that is connected with dividing plate 2-1 bottom, described arrester handcart 1 is after sliding into service position on base plate 2-3, three moving contact 1-2 insert respectively three fixed contact 2-2, the threephase cable of lightning arrester is by moving, fixed contact is connected with the three-phase bus in bus-bar room 4.
As shown in Figure 2, the upper band of the car body 1-1 of arrester handcart 1 of the present utility model jug 1-4.
Lightning arrester of the present utility model is high-voltage arrester.
As shown in Figure 3, valve mechanism 2 of the present utility model also comprises the cover plate 2-4 that can cover fixed contact 2-2; The both sides of base plate 2-3 are provided with the guide rail into arrester handcart 1 slide-and-guide.
During concrete enforcement:
Lightning arrester is arranged on arrester handcart, the lightning arrester valve mechanism is arranged between cable vault and bus-bar room, the fixed contact of lightning arrester valve mechanism directly is connected with the bus-bar room busbar, arrester handcart is placed on lightning arrester valve mechanism guide rail, when arrester handcart is pushed into service position, its movable contact refers to contact with lightning arrester valve mechanism fixed contact, and lightning arrester is in running order; When arrester handcart shook out, its movable contact referred to from lightning arrester valve mechanism fixed contact, throwing off, and the cover plate on the lightning arrester valve mechanism falls fixed contact sealing isolation simultaneously, now, can open cable vault's cabinet goalkeeper arrester handcart and pull out.Thereby realize namely can carrying out repair and maintenance work to lightning arrester in the charged situation of bus, can avoid again personnel's injures and deaths of getting an electric shock.
The utility model does not relate to partly all prior aries that maybe can adopt same as the prior art to be realized.
