Abstract
A kind of by used automatic air opens circuit being used for of forming such as self-locking shaft 1, baffle plate 2, drawstring 3, tripping piece 4, snap close 5, armature 6, iron core 7, coil 8, support 15, support shaft 16 and the self-locking release of low-voltage electrical apparatus such as contactor, be by armature of a compact electromagnetic system control, drive fastener system by armature, by the moving contact and the mounting system thereof of fastener system control automatic air circuit breaker or contactor.Thus, be used in the circuit breaker and can improve breaking capacity, make opening speed reduce to 8ms by 12ms; Be used in and can make the coil of existing electromagnetic system be reduced to 1/3 on the contactor, iron core dwindles 1/6, and can economize on electricity more than 90%.
Description
The present invention relates to a kind of self-locking release that can be used in the low-voltage electrical apparatus.
Comparatively advanced both at home and abroad Direct Action Type contactor and the above Energy-saving coil formula contactor of 100A all are not provided with trip gear, all be that operation is switched on or switched off electric current between AC power electromagnet Shun, thereby complicated to the processing technology requirement of solenoid, iron core, technology acuracy requires also high.Otherwise,, also can cause the not firm or misoperation of contactor adhesive even accidents such as coil scaling loss are taken place because of spread of voltage often because the unreasonable iron core, short-circuited conducting sleeve of causing of parameter damages.The operating mechanism of automatic air circuit breaker all is to adopt four-link mechanism, " is closed " or " branch " by manual operation, when meeting accident accident, promotes four-link mechanism by thermal element or electromagnetism off line device circuit breaker is disconnected.This trip gear has complex manufacturing, cost height, shortcomings such as poor reliability.
For overcoming above deficiency, the invention provides a kind of self-locking release that can be used for low-voltage electrical apparatus such as aspects such as contactor or automatic air circuit breaker, to reach or to realize the low-pressure electronic equipment product reduced volume, reduce cost, simplify technology, saves energy, improve the purpose in useful life.
The present invention is design like this: set up a kind of self-locking release on existing contactor; Existing automatic air circuit breaker is done following improvement, by the self-locking release directly and the Machinery Control System in the circuit breaker be used the promotion snap close, save used four-link mechanism.The present invention is achieved in that by armature of a compact electromagnetic system control, drives fastener system by armature, by the moving contact and the mounting system thereof of fastener system control automatic air circuit breaker or contactor.
Advantage of the present invention is tangible: 1 if be used in the circuit breaker and can directly promote snap close, and opening speed is reduced to 8ms by 12ms, thereby has improved breaking capacity; 2, if be used on the contactor, can make the coil of existing electromagnetic system dwindle 1/3, iron core dwindles 1/6, and available electrical pure iron replaces silicon steel sheet, save short-circuited conducting sleeve, and because of action back outage between contactor solenoid Shun, the frequency of operation per minute of contactor reaches as high as 60 times, can economize on electricity and can reach more than 90%.
Now reach should be used in contactor with reference to the accompanying drawings and further specify principle of the present invention and embodiment, will more deep understanding be arranged to the present invention by this explanation, but not limit practical range of the present invention at all.
Longitudinal sectional drawing when the self-locking release that Fig. 1 uses for a kind of low-voltage electrical apparatus of the present invention is used for the contactor dropout.
Longitudinal sectional drawing when Fig. 2 is used for the contactor self-locking for it.
Fig. 3 is used for the electrical schematic diagram of contactor for it.
As shown in Figure 1, self-locking shaft 1 is fixed on the drawstring 3 for the shaft coupling that electromagnetic system pins or disconnects, and drawstring 3 is the connecting rods that can spur the contact supporting activity up and down that are fixed on existing contactor or the moving iron core of automatic air circuit breaker.Plate washer 2 is for guaranteeing self-locking shaft 1 upper and lower mobile track.Be fixed with support 15 on base plate 12, support 15 upper ends are provided with support shaft 16, and snap close 5 and armature 6 are fixed together and are installed on the support shaft 16, and the lower end of snap close 5 is provided with snap close axle 18 and extension spring 17, and the other end of extension spring 17 is fixed on the tripping axle 19.Tripping piece 4 is fixed on the tripping axle 19, but is provided with spring 13 so that 4 swings of tripping piece between tripping piece 4 and tripping axle 19, and tripping piece 4 front ends are provided with tripping 14.Be provided with an iron core 7 below the armature 6 and be wound with coil 8.9 is the upper core of contactor, and 10 is the solenoid of contactor, and 11 is the lower core of contactor.J01 among Fig. 3 is the master switch of contactor, and QA is the close push button switch, and TA is the cut-off push button switch, and C is the travel switch of contactor coil 10, and J is provided with a step-down rectifier circuit Z for the coil 8 of self-locking release of the present invention in the coil 8.
The operation principle of self-locking release of the present invention still is example with the contactor; When pressing control button QA, the coil 10(closure of contactor).By step-down circuit Z coil 8(J) work, make armature 6 adhesives.Simultaneously the probe of contactor mounting system promotes drawstring 3, makes self-locking shaft 1 be stuck in the centre position of plate washer 2 and tripping piece 4, is stuck on the trip shaft 18 with the tripping 14 of tripping piece 4 one, to making the tripping piece 4 can not deflection and be in long-term lock-out state (see figure 2).After self-locking shaft 1 put in place, the travel switch C that is located at the probe of contactor mounting system opened circuit contactor coil 10.But because of the self-locking action of self-locking release, probe of contactor remains in closure state.
When pressing disconnection push switch TA, contactor opens circuit, self-locking release power supply disconnects (coil 8 opens circuit) armature 6 makes the tail end A place impact tripping piece 4 of armature 6 under the promotion of the strong spring of counter-force (not providing among the figure) upper end, tripping 4 is outwards compiled to be changeed, break away from snap close axle 18, make self-locking 1 fall the bottom (see figure 1) of plate washer 2 and tripping piece 4, the self-locking release is in off-state.
According to above-mentioned principle and structure, the coil 8 of embodiments of the invention is selected the enamelled wire of 0.09 millimeter of φ for use, and 7(makes with electric steel plate around magnet) 3000 circles, base plate 12 and self-locking shaft 1, armature 6, support 15, lock machine axle 18 etc. are all made by metal material.
