The utility model discloses install arrester and earthing switch on same support to certain installation space has been practiced thrift to reducible support, is favorable to the installation and the maintenance of other equipment, reduces the construction degree of difficulty.
Description
Technical Field
The utility model relates to a transformer engineering equipment field, concretely relates to take earthing switch's arrester.
Background
In the outdoor transformer substation: according to the form of the power distribution device, the power distribution device is divided into AIS, GIS and HGIS.
Existing AIS power distribution devices are classified into AIS power distribution devices of conventional independent circuit breakers and AIS power distribution devices of isolation circuit breakers.
The existing lightning arresters are divided into open type lightning arresters and built-in lightning arresters of combined electrical appliances (GIS and HGIS). The open type lightning arresters are all independent equipment types.
The existing grounding switches are divided into open-type grounding switches and built-in grounding switches of combined electrical appliances (GIS and HGIS). The open-type grounding switch is divided into two types, one type is an independent grounding switch, the other type is a grounding switch integrated with the isolating circuit breaker, the grounding switch integrated with the isolating circuit breaker can realize the integrated manufacture of the grounding switch, the circuit breaker and the mutual inductor, has the double functions of the circuit breaker, the grounding switch and the mutual inductor, and can replace the traditional open-type equipment. However, the grounding switch integrated with the disconnecting circuit breaker can only realize grounding of the lower end fracture of the circuit breaker, and cannot realize grounding of the upper end fracture, so that an independent grounding switch is generally adopted by an outdoor transformer substation.
The existing open type lightning arrester is installed through a support, the existing independent grounding switch is also installed through the support, the existing open type lightning arrester and the existing independent grounding switch need two sets of supports and occupy certain space, so that the number of devices and the occupied area are large, and the construction and maintenance difficulty is increased.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a take earthing switch's arrester is provided, reduce equipment quantity and area, be convenient for construction and maintenance.
The utility model provides a technical scheme that technical problem adopted is: take earthing switch's arrester, which comprises a bracket, the top of support is provided with the arrester, the top of arrester is provided with arrester equalizer ring, still includes earthing switch, earthing switch is fixed to be set up on the upper portion of support, and earthing switch is connected with earthing switch mechanism case, earthing switch mechanism case fixed mounting is on the support.
Further, the grounding switch is fixed on a porcelain bushing of the lightning arrester
Further, the grounding switch mechanism boxes are all mounted on the support through screws.
Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses install arrester and earthing switch on same support to certain installation space has been practiced thrift to reducible support, is favorable to the installation and the maintenance of other equipment, reduces the construction degree of difficulty.
Drawings
FIG. 1 is a schematic view of the present invention;
reference numerals: 1-a support; 2-a lightning arrester; 3-a grounding switch; 4-earthing switch mechanism box; and 5, grading rings of the lightning arrester.
Detailed Description
The present invention will be further explained with reference to the drawings and examples.
The utility model discloses a take earthing switch's arrester, which comprises a bracket 1, the top of support 1 is provided with arrester 2, the top of arrester 2 is provided with arrester equalizer ring 5, still includes earthing switch 3, earthing switch 3 is fixed to be set up on the upper portion of support 1, and earthing switch 3 is connected with earthing switch mechanism case 4, 4 fixed mounting of earthing switch mechanism case are on support 1.
The support 1 is vertically arranged and used for supporting the lightning arrester 2, the grounding switch 3 and other components, and various insulating materials with high strength, high temperature resistance and corrosion resistance, such as ceramic materials and the like, can be adopted.
Arrester 2 adopts current common arrester, including the inside discharge structure of insulator and insulator, in order to guarantee that the voltage distribution of arrester 2 is even, the top of arrester 2 has set up arrester equalizer ring 5 for balanced stray capacitance to ground makes voltage distribution even, avoids arrester 2 to take place the local breakdown and damage.
Earthing switch 3 adopts current isolator, can be with earthing switch 3 direct mount on support 1, also can fixed mounting on the porcelain cover of arrester 2, specifically, the porcelain cover at arrester 2 is installed to accessible bolt, screw etc..
Have components and parts such as miniature circuit breaker, button, contactor, thermorelay, temperature and humidity controller in the earthing switch mechanism case 4, can control earthing switch 3, play isolation power, change system operation mode, carry out functions such as switching operation, adopt prior art can, installed parts such as accessible screw are installed in the bottom of support 1.
To sum up, the utility model discloses a 1 simultaneous installation arrester 2 and earthing switch 3 of a support, with arrester 2 and earthing switch 3 integration together, have traditional arrester and earthing switch's function concurrently to certain space has been practiced thrift to reducible a support 1, under the limited circumstances of installation space, is favorable to the installation and the maintenance of other equipment, reduces the construction degree of difficulty.
