Abstract
A spring energy storage mechanism of a disconnecting switch comprises a support, an operating rod, a levorotation steel wire spring and a dextrorotation steel wire spring. An opening on the rear end of the support is connected to the edge part of a base on the disconnecting switch, and two blind holes which are close to each other are formed in the inner surface of the lower part of the front end surface. The operating rod is an L-shaped rod formed by a handle operating rod and a swinging arm in an integrated manner. The front part of the handle operating rod penetrates through the upper part of the front end surface of the support and extends to the outer part. Two spring arranging holes are formed in two sides of the outer end of the swinging arm, the rear part of the outer end is connected to a limiting block on a moving contact set, and the limiting block is connected to a contact support. The levorotation steel wire spring and the dextrorotation steel wire spring are arranged symmetrically, one end of the levorotation steel wire spring and one end of the dextrorotation steel wire spring are inserted into the two spring arranging holes in the outer end of the swinging arm, and the other ends of the levorotation steel wire spring and the dextrorotation steel wire spring are inserted into the two blind holes in the support. The spring energy storage mechanism of the disconnecting switch is advantageous in that the double-spring mechanism is provided, the two steel wire springs in relatively small areas on two sides of the spring energy storage mechanism provide component forces to break balance, and the double-spring mechanism is capable of outputting double torque forces under the condition that the diameter remains the same.
Description
Technical field
The utility model belongs to high-voltage switch electric appliance technical field, particularly relates to a kind of spring energy agency of isolating switch.
Background technology
Isolating switch is that a kind of being mainly used in will need the part having a power failure to isolate reliably with live part in high voltage distribution installation, with assurance equipment or line maintenance work safety and carry out the high-voltage switch electric appliance of electrical isolation, mainly formed by housing, pedestal, fixed contact group, moving contact group and spring energy agency.But, there is following point in the spring energy agency at present conventional isolating switch: because it is the mode that adopts joystick and the combination of single wire spring, in the time that needs strengthen spring torsion, because inherent structure is limit, therefore can only adopt the mode of overstriking wire diameter, so not only can reduce the useful life of spring, and easily stuck at dead point near zone, and result affects the normal use of product.
Summary of the invention
In order to address the above problem, the purpose of this utility model is to provide a kind of spring energy agency that can prevent the stuck isolating switch of spring.
The spring energy agency of the isolating switch that in order to achieve the above object, the utility model provides comprises support, joystick, left-handed wire spring and dextrorotation wire spring; Its medium-height trestle is box typed structure, and rear end is formed with opening, and opening is connected to the edge of isolating switch top base, is formed with two blind holes close to each other in front end face lower inner surface simultaneously; Joystick is the L shaped bar being integrally formed by trigger rod and swing arm, wherein the front portion of trigger rod is run through the front end face top of support and is extended to outside, the both sides, outer end of swing arm are formed with two springs hole are set, rear portion, outer end is connected with the guide vane end stop in moving contact group simultaneously, and guide vane end stop joins with contact supporting; Left-handed wire spring and dextrorotation wire spring are symmetrical set, and two springs that one end is inserted in respectively swing arm outer end arrange in hole, and the other end is inserted in respectively in two blind holes on support.
Described left-handed wire spring is identical with dextrorotation wire spring structure.
The spring energy agency tool of the isolating switch that the utility model provides has the following advantages:
1, provide dual spring mechanism, provide component to disequilibrate by two wire springs in spring energy agency both sides respectively in compared with zonule;
2, dual spring mechanism can export double torsion in the situation that diameter is constant.
3, little to existing product structural modification.

Embodiment
The spring energy agency of isolating switch the utility model being provided below in conjunction with the drawings and specific embodiments is elaborated.
As shown in Fig. 1-Fig. 4, the spring energy agency of the isolating switch that the utility model provides comprises support 1, joystick 2, left-handed wire spring 3 and dextrorotation wire spring 4; Its medium-height trestle 1 is box typed structure, and rear end is formed with opening, and opening is connected to the edge of isolating switch top base 5, is formed with two blind holes 11 close to each other in front end face lower inner surface simultaneously; The L shaped bar of joystick 2 for being integrally formed by trigger rod 6 and swing arm 7, wherein the front portion of trigger rod 6 is run through the front end face top of support 1 and is extended to outside, the both sides, outer end of swing arm 7 are formed with two springs hole 10 are set, rear portion, outer end is connected with the guide vane end stop 8 in moving contact group simultaneously, and guide vane end stop 8 joins with contact supporting 9; Left-handed wire spring 3 and dextrorotation wire spring 4 are symmetrical set, and two springs that one end is inserted in respectively swing arm 7 outer ends arrange in hole 10, and the other end is inserted in respectively in two blind holes 11 on support 1.
Described left-handed wire spring 3 is identical with dextrorotation wire spring 4 structures.
The isolating switch operation principle that the spring energy agency that the utility model provides is now installed is described below:
In the time of needs combined floodgate or separating brake, first by operating personnel along along or the outer end of turning handle action bars 6 counterclockwise firmly, at this moment also will rotate to same direction with swing arm 7 outer ends of trigger rod 6 one, make thus dextrorotation wire spring 3 and left-handed wire spring 4 produce distortion and accumulation of energy, until dextrorotation wire spring 3 and left-handed wire spring 4 behind dead point, the energy of its storage is by abrupt release, thereby make coupled guide vane end stop 8 and contact supporting 9 drive whole moving contact group together from a sidesway of pedestal to opposite side, until the moving contact in moving contact group is in contact with one another or separates with the fixed contact on pedestal, complete thus and close a floodgate or sub-switching operation process.As shown in Figure 5, the isolating switch structure that the utility model provides in the time of closing position as shown in Figure 6 for the isolating switch structure that the utility model provides in the time of open position.
