Abstract
The invention discloses a spring energy storage mechanism for a disconnecting switch. The spring energy storage mechanism comprises a support, an operating lever, a left-handed wire spring and a right-handed wire spring; a rear-end opening of the support is connected with the edge of a substrate of the disconnecting switch, and the inner surface on the lower part of the front end face of the support is provided with two blind holes close to each other; the operating lever is an L-shaped lever which is formed by integrating a handle operating rod and a swinging arm; the front part of the handle operating rod penetrates through the upper part of the front end face of the support and extends to the outside; the two sides of the outer end of the swinging arm are provided with two spring setting holes, and the rear of the outer end is connected with a limiting block on a moving contact group; the limiting block is connected with a contact support; the left-handed and right-handed wire springs are symmetrically arranged, one ends of the left-handed and right-handed wire springs are respectively inserted into the two spring setting holes at the outer end of the swinging arm, and the other ends are respectively inserted into the two blind holes in the support. The spring energy storage mechanism has the advantages that a dual spring mechanism is provided, and the two wire springs respectively provide component force to break the balance in smaller areas on the two sides of the spring energy storage mechanism; the dual spring mechanism can output double torsion under the condition that the diameter is not changed.
Description
Technical field
The invention belongs to high-voltage switch electric appliance technical field, particularly relate 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 by housing, pedestal, fixed contact group, moving contact group and spring energy agency, formed.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, when 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 object of the present invention is to provide a kind of spring energy agency that can prevent the isolating switch that spring is stuck.
In order to achieve the above object, the spring energy agency of isolating switch provided by the invention 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; The L shaped bar of joystick for 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 isolating switch provided by the invention has the following advantages:
1, provide dual spring mechanism, in spring energy agency both sides, by two wire springs, provide component to disequilibrate 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
Below in conjunction with the drawings and specific embodiments, the spring energy agency of isolating switch provided by the invention is elaborated.
As shown in Fig. 1-Fig. 4, the spring energy agency of isolating switch provided by the invention 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 close to each other 11 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 spring energy agency provided by the invention is now installed is described below:
When 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 with fixed contact on pedestal or is separated, complete thus and close a floodgate or sub-switching operation process.When open position, as shown in Figure 5, when closing position, isolating switch structure provided by the invention as shown in Figure 6 for isolating switch structure provided by the invention.
