Abstract
The utility model provides a novel explosion-proof type vacuum feeder switch for mine use, which comprises an explosion-proof housing, and an incoming line soldering terminal and an outgoing line soldering terminal arranged on the explosion-proof housing. A permanent magnet vacuum circuit breaker and an isolating switch are arranged in the explosion-proof housing; the incoming line soldering terminal is connected to the inlet wire end of the isolating switch through a cable conducting wire; the outlet wire end of the isolating switch is connected to the inlet wire end of the permanent magnet vacuum circuit breaker; the outlet wire end of the permanent magnet vacuum circuit breaker is connected with the outgoing line soldering terminal through a cable conducting wire; a handle is arranged on the explosion-proof housing; and an opening shaft linked with the isolating switch is arranged on the inner side of the handle. The utility model has the advantages of ingenious design, simple structure, safety and reliability, long service life, and easiness in maintenance.
Description
Technical field
The utility model relates to a kind of explosion-proof switch, specifically, relates to a kind of new type mining flame-proof type vacuum feed switch.
Background technology
Present common flame-proof mine vacuum feed switch is mainly used in the power supply system under the coal mine; Its structure comprises the control panel and the blocking mechanism of elements such as being installed in the interior mechanical freeze mode low-voltage vacuum circuit breaker of flameproof enclosure, installation protector; Wherein, machinery freeze mode vacuum circuit-breaker is equipped with the three-phase vacuum tube, its operation principle is, three releases, i.e. device for under-voltage releasing equipment, shunt release and hand trip gear are after the vacuum tube contact closure, there is a machinery to keep hook in the circuit breaker, hook armature, the other end that keeps hook is by another mechanical device button bit, thus make close a floodgate reliable and stable; The separating brake rotating shaft is controlled by machinery threads off, under-voltage coil, shunt opening coil, and wherein any control device action all can make the separating brake rotating shaft rotate, and reaches the purpose of separating brake; The advantage of this two-stage tripping mechanism is, can make circuit breaker keep "on" position with minimum power (under-voltage coil is charged), and power controlling is little, and opening time is short.
But, this mechanical freeze mode flame-proof type vacuum feed switch, because environment for use is abominable, vacuum circuit-breaker quality problems etc. may cause the phenomenon of vacuum tube adhesion; No matter and whether adhesion of vacuum tube, feeding switch is after receiving sub-gate signal, system can give tacit consent to circuit breaker and cut off the power supply; So just exist feeding switch to show outage, and actual still charged situation; If open door closure maintenance this moment or check problems such as a series of potential safety hazard such as cause that personnel get an electric shock easily, even can cause coal mine gas from explosion, cause mine safety accidents; For this reason, people are seeking a kind of desirable technical solution always.
Summary of the invention
The utility model is at the deficiencies in the prior art, and a kind of deft design, simple in structure, safe and reliable new type mining flame-proof type vacuum feed switch are provided.
The technical scheme that the utility model adopted is as follows: a kind of new type mining flame-proof type vacuum feed switch, it includes flameproof enclosure, is arranged on inlet wire binding post and outlet binding post on the flameproof enclosure, in described flameproof enclosure, be provided with permanent magnetism vacuum circuit-breaker and isolating switch, described inlet wire binding post connects described isolating switch end of incoming cables by cable conductor, described isolating switch leading-out terminal connects described permanent magnetism vacuum circuit-breaker end of incoming cables, and described permanent magnetism vacuum circuit-breaker leading-out terminal connects described outlet binding post by cable conductor; Described flameproof enclosure is provided with handgrip, and the separating brake axle of described isolating switch links in the inboard of described handgrip.
The utility model has substantive distinguishing features and progress with respect to prior art, and specifically, this vacuum feed switch has following advantage:
1, owing to adopt the permanent magnet mechanism low-voltage vacuum circuit breaker to replace traditional mechanical mechanism low-voltage vacuum circuit breaker, the form that simplifies the structure, thus improved the reliability and the useful life of mechanism greatly; And owing to adopt the permanent magnetism vacuum circuit-breaker, frequent operation for a long time under the situation of not opening door closure is really accomplished few maintenance, freedom from repairs;
2, in flameproof enclosure, increase inlet wire side isolating switch, got rid of the potential safety hazard that vacuum circuit-breaker causes because of the vacuum tube adhesion, fundamentally solved the potential safety hazard of vacuum feed switch under the coal mine, improved underground mine use electricity safety.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
For further instruction design feature of the present utility model, the existing embodiment that provides in conjunction with the accompanying drawings:
As shown in Figure 1, a kind of new type mining flame-proof type vacuum feed switch includes flameproof enclosure 1, is arranged on inlet wire binding post 2 and outlet binding post 3 on the flameproof enclosure 1; Wherein, in described flameproof enclosure 1, be provided with permanent magnetism vacuum circuit-breaker 4 and isolating switch 7, described inlet wire binding post 2 connects described isolating switch 7 ends of incoming cables by cable conductor, described isolating switch 7 leading-out terminals connect described permanent magnetism vacuum circuit-breaker 4 ends of incoming cables, and described permanent magnetism vacuum circuit-breaker 4 leading-out terminals connect described outlet binding post 3 by cable conductor 6;
Described flameproof enclosure 1 is provided with handgrip 5, and the separating brake axle of described isolating switch 7 links in the inboard of described handgrip 5.
Electric power incoming line is connected on the isolating switch 7 by inlet wire binding post 2, cable conductor, causes on the outlet binding post 3 through permanent magnetism vacuum circuit-breaker 4, cable conductor 6 again, forms complete loops with this; When the needs outage was uncapped, turn placed the handgrip 5 on the flameproof enclosure 1, drove the separating brake axle motion of isolating switch 7, thereby isolating switch 7 is disconnected, to form the physics outage.
The utility model changes the mode of connection of feeding switch in the past; increase an isolating switch 7 in permanent magnetism vacuum circuit-breaker 4 inlet wire sides; shutting down maintenance etc. at flame-proof type vacuum feed switch need open under the situation of door closure; rotate the handgrip on the flameproof enclosure; isolating switch 7 is disconnected; cause the physics outage, thereby solve the potential safety hazard that causes because of the vacuum tube adhesion.
