The utility model relates to a kind of VD4 type contact of breaker spring Special maintenance tool, comprise hollow Rotary-table and hollow cylinder, the diameter of the bottom of described Rotary-table is greater than the diameter on the top of described Rotary-table, and the diameter of the bottom of described Rotary-table and described cylindrical equal diameters; Described Rotary-table and described cylinder are coaxially arranged, and the bottom of described Rotary-table is welded on described cylindrical top.The utility model owing to have employed technique scheme, can realize simple and convenient, safety change touch spring, and adopt integrated formed structure, simple and practical.
Description
Technical field
The utility model relates to electrical engineering field, is specifically related to a kind of VD4 type contact of breaker spring Special maintenance tool.
Background technology
The 12kV VD4 type vacuum circuit-breaker that in electric power system, most of power station all adopts ABB AB to produce, circuit breaker adopts the larger spring of elastic force to be fixed compression.When disconnecting the faults such as big current when circuit breaker, spring may be burned, and now just needs to change touch spring.There is following inconvenience in the operation of current replacing spring:
(1) touch spring interval is narrow and small, operation inconvenience;
(2) during dismounting, touch spring energy is strong, and elastic force is comparatively large, is difficult to uniaxial direct tensile support large, is not easy spring to be installed to well on contact, may injures operating personnel during installation with hand.
Summary of the invention
The purpose of this utility model, exactly in order to solve above-mentioned prior art Problems existing, and a kind of VD4 type contact of breaker spring Special maintenance tool is provided, overcome replacing contact of breaker spring force at present larger, not easily strut the difficult point carrying out changing, can realize simple and convenient, safety change touch spring, and adopt integrated formed structure, simple and practical.
The technical scheme realizing above-mentioned purpose is: a kind of VD4 type contact of breaker spring Special maintenance tool, comprise hollow Rotary-table and hollow cylinder, the diameter of the bottom of described Rotary-table is greater than the diameter on the top of described Rotary-table, and the diameter of the bottom of described Rotary-table and described cylindrical equal diameters; Described Rotary-table and described cylinder are coaxially arranged, and the bottom of described Rotary-table is welded on described cylindrical top.
Above-mentioned a kind of VD4 type contact of breaker spring Special maintenance tool, wherein, described Rotary-table and described cylinder are integrated formed structure.
Above-mentioned a kind of VD4 type contact of breaker spring Special maintenance tool, wherein, described cylinder and Rotary-table all adopt stainless steel.
VD4 type contact of breaker spring Special maintenance tool of the present utility model, adopt integrated formed structure, simple and practical, can realize simple and convenient, safety change touch spring.
Accompanying drawing explanation
Fig. 1 is the structural representation of VD4 type contact of breaker spring Special maintenance tool of the present utility model;
Fig. 2 is the front view of VD4 type contact of breaker spring Special maintenance tool of the present utility model.
Embodiment
In order to make those skilled in the art can understand the technical solution of the utility model better, below in conjunction with accompanying drawing, the utility model is described in further detail.
Refer to Fig. 1 and Fig. 2, embodiment of the present utility model, a kind of VD4 type contact of breaker spring Special maintenance tool, comprise hollow Rotary-table 1 and hollow cylinder 2, the diameter of the bottom of Rotary-table 1 is greater than the diameter on the top of Rotary-table 1, and the equal diameters of the diameter of the bottom of Rotary-table 1 and cylinder 2; Rotary-table 1 and cylinder 2 are coaxially arranged, and the bottom of Rotary-table 1 is welded on the top of cylinder 2.Rotary-table 1 and cylinder 2 are in integrated formed structure.Cylinder 2 and Rotary-table 1 all adopt stainless steel.
Use VD4 type contact of breaker spring Special maintenance tool of the present utility model, the step of dismounting VD4 type contacts for vacuum-break switches spring:
Step 1: one section, touch spring Special maintenance tool cylinder is enclosed within contact of breaker;
Step 2: by needing the spring changed to strut a little, be socketed on service kit;
Step 3: finally spring is moved to Rotary-table along service kit shell from cylinder, can disassemble spring smoothly.
Use VD4 type contact of breaker spring Special maintenance tool of the present utility model, the step of VD4 type contacts for vacuum-break switches spring be installed:
Step 1: slowly move to cylindrical shell from one end that the diameter of Rotary-table is little by needing the spring changed;
Step 2: the cylinder of the contact of breaker spring Special maintenance tool that new spring is housed is enclosed within contact of breaker;
Step 3: move on contact along cylindrical shell by spring, then moves to contact relevant position by spring.
VD4 type contact of breaker spring Special maintenance tool of the present utility model, utilize the feature that one end diameter of open circles stage body is little, by spring is moved in cylinder along Rotary-table case surface, in this process spring is strutted, carry out dismounting and the installation of spring.This device has following features:
(1) can reach by change cylinder, Rotary-table size the touch spring being applicable to all types of vacuum circuit-breakers.
(2) this device adopts integrated structure design, singlely can operate, rational in infrastructure, easy to use;
(3) size Selection of this device designs after contrast breaker terminal size, adopts stainless steel, guaranteed performance also can avoid waste.
Above embodiment is only for illustration of the utility model, but not to restriction of the present utility model, person skilled in the relevant technique, when not departing from spirit and scope of the present utility model, various conversion or modification can also be made, therefore all equivalent technical schemes also should belong to category of the present utility model, should be limited by each claim.
Claims (3)
1. a VD4 type contact of breaker spring Special maintenance tool, it is characterized in that, comprise hollow Rotary-table and hollow cylinder, the diameter of the bottom of described Rotary-table is greater than the diameter on the top of described Rotary-table, and the diameter of the bottom of described Rotary-table and described cylindrical equal diameters; Described Rotary-table and described cylinder are coaxially arranged, and the bottom of described Rotary-table is welded on described cylindrical top.
2. a kind of VD4 type contact of breaker spring Special maintenance tool according to claim 1, it is characterized in that, described Rotary-table and described cylinder are integrated formed structure.
