Description
Technical field
The utility model relates to a kind of breaker mechanism of Sub-gate release device, particularly a kind of breaker mechanism with two Sub-gate release devices of low cost of manufacture.
Background technology
Circuit breaker is one of electric equipments of transformer station.It not only can cut off and connect high-tension line and various zero load and load current when system is normally moved; and when system breaks down; interaction energy by protective relaying device excises various overload electric currents and short circuit current, the generation of Accident prevention scope and expansion automatically, rapidly, reliably.Sulfur hexafluoride breaker is to utilize sulfur hexafluoride gas to do the novel switched of dielectric and arc-extinguishing medium.Sulfur hexafluoride gas is colourless, tasteless, nontoxic, and non-flammable inert gas has very high dielectric strength and good arc extinction performance, and dielectric strength is considerably beyond traditional insulating gas.Therefore, it can improve reliability and the fail safe of electric power system for electric power system.
Traditional 40.5kV sulfur hexafluoride breaker mechanism only has a Sub-gate release device.This mechanism in actual use, due to the various reasons of control system and mechanism self, exists tripping electromagnet to burn or the situation of clamping stagnation once in a while.For electric power system, tripping electromagnet burns or clamping stagnation means this circuit breaker separating brake smoothly, causes circuit breaker overstep tripping, and then causes large-area power-cuts, has a strong impact on normal life.
Utility model content
The technical problem that the innovation will solve is to provide a kind of breaker mechanism with two Sub-gate release devices of low cost of manufacture.
For solving the problems of the technologies described above, the technical solution of the utility model is:
The breaker mechanism with two Sub-gate release devices, comprise: two groups of tripping electromagnets independently, a separating brake semiaxis is placed between two separating brake top boards and bent plate, and adjusted by bolt, separating brake semiaxis back-moving spring, separating brake fanning strip, separating brake fanning strip back-moving spring, manual brake separating handle, connecting rod are separately positioned on the inside and outside two sides of support.
In some embodiments, separating brake semiaxis is contained in support by bearing.
In some embodiments, adjusting bolt is contained in the gap of the iron core of two separating brake top board adjusted tripping electromagnets.
In some embodiments, separating brake semiaxis back-moving spring, separating brake fanning strip back-moving spring reset amount increase the gap that booster action electromagnet produces.
In some embodiments, connecting rod drives the inside and outside side component motion of breaker mechanism of two Sub-gate release devices.
In some embodiments, have two and overlap independently electromagnet, and respectively by two independently secondary circuit control.
In some embodiments, the length of two separating brake top boards is 90mm, increases moment of inertia.
As the content of this utility model, the practical problem of solution can realize the two separating brakes of circuit breaker and thread off; Relative original structure, this device does not carry out large structural change, utilized origianl component, original separating brake top board is modified to and meets the new top board that the length of two separating brake requirements is 90mm, increase due to moment of inertia, therefore corresponding with it back-moving spring is mated again, reach the needed functional requirement of mechanism.Compare with original structure, mechanism has increased the ability that two separating brakes are threaded off, and has greatly improved the separating brake reliability of mechanism, has guaranteed the resistance to overturning of mechanism; For realizing pair Sub-gate release device of separating brake dropout ，Gai mechanism, increased by one group of tripping electromagnet on original basis, and top board and back-moving spring are recalculated to analysis and coupling, change cost is low, and parts utilance is high, and economic worth is high.The original structure of having avoided only having a set of sub-gate circuit can only overstep tripping when electromagnet akinesia situation, avoided the extension of accident, increased circuit breaker reliability of operation in system.

Embodiment
Below in conjunction with accompanying drawing 1 ~ 4 and specific embodiment, the breaker mechanism of of the present utility model pair of Sub-gate release device is described in further detail.
As shown in Fig. 1 ~ 4, a kind of breaker mechanism with two Sub-gate release devices, comprising: two groups of tripping electromagnets (8,9) independently, and respectively by two independently secondary circuit control;
One is contained in the separating brake semiaxis 2 in support 1 by bearing, and separating brake semiaxis 2 is placed between two separating brake top boards 6 and bent plate 7, and is adjusted by bolt 4;
Be separately positioned on separating brake semiaxis back-moving spring 16, separating brake fanning strip 13, separating brake fanning strip back-moving spring 14, manual brake separating handle 11, the connecting rod 10 of the inside and outside two sides of support 1.
Adjusting bolt 3,5 is contained on two separating brake top boards 6, regulates the gap of the iron core of tripping electromagnet 8,9; Described separating brake semiaxis back-moving spring 16, separating brake fanning strip back-moving spring 14 reset amounts increase the gap that booster action electromagnet produces; Connecting rod 10 drives the inside and outside component movement of the breaker mechanism of two Sub-gate release devices; A kind of breaker mechanism with two Sub-gate release devices that the utility model provides, its pair of top board that separating brake top board 6 is 90mm for length, increases moment of inertia.
The breaker mechanism of of the present utility model pair of Sub-gate release device, at the coil of electromagnet 9, obtain when electric, with the upwards action of iron core of motor magnet, iron core action drives two separating brake top boards 6 to turn clockwise, two separating brake top boards 6 rotarily drive separating brake semiaxis 2 and turn clockwise, and separating brake one-level is threaded off and open.After separating brake one-level is threaded off and is opened, separating brake fanning strip 13 clockwise rotates under the effect of separating brake connecting lever 12, separating brake secondary is threaded off and is opened, separating brake connecting lever 12 clockwise rotates, tripping spring releases energy, by tripping spring pull bar, the inside and outside output toggle arm of lead agency moves to open position, and the contact in arc control device is exported connecting rod with moving to open position by mechanism simultaneously.If electromagnet 9 exists in the situation of damage or clamping stagnation, when electric electromagnet 9 be failure to actuate, secondary relay protection is postponing, after the regular hour, sub-gate signal is inputted to second sub-gate circuit, tripping electromagnet 8 is obtained electric, and operating principle is consistent with the operating principle of first tripping electromagnet.
