Background technology
Mine explosion-suppression and intrinsic safety type multiloop vacuum electromagnetic starter is the conventional combined electrical apparatus in a kind of mine, and it is mainly used to control and protection motor, and in mining industry, vacuum magnetic starter is an important electric equipment.Therefore, require vacuum magnetic starter there is larger Current Control ability and more improve protective value.But the vacuum magnetic starter recent two decades using does not at present have large breakthrough technically, and its function ratio is more single, has many deficiencies in reliability, fail safe, practicality and technical performance.And due to its work under bad environment, moisture and dust can affect internal components work, therefore shell and the sealing property of door body are had relatively high expectations, particularly door closure and switch,, therefore sealing is not tight, easily leave space, affect security performance and the useful life of product.Therefore imagination provides a kind of new device to solve this problem.
Summary of the invention
For the problems referred to above, it is high that the purpose of this utility model is to provide a kind of security performance, easy to operate, practical mine flameproof and intrinsic safety type multi-circuit vacuum electromagnetic starter reliably.
Realize the technical solution of the utility model as follows:
Mine flameproof and intrinsic safety type multi-circuit vacuum electromagnetic starter, comprise casing, be arranged on the operating handle that casing one side is connected through the hinge, be arranged on the skid of bottom half, inside, casing top is provided with wire connection cavity, wire connection cavity two ends are provided with the radial outgoing wire mouth that outlet nozzle and casing are provided with, on described casing, be also provided with door closure, door closure is controlled by the control unit being arranged on casing, control unit comprises switch handle, scram button and deadlock lever, switch handle is fixed on the mounting panel in casing, switch handle is connected with the isolating switch that is arranged on box house by shaft coupling, scram button is arranged between switch handle and door closure, the other end of scram button is fixed on mounting panel, deadlock lever is arranged on scram button top, the deadlock lever other end is connected with the travel switch that is arranged on box house by travel switch mounting plate, in described casing, be also provided with control unit.
Described control unit comprises frame, be fixed on the insulated terminal of frame one side lower end, insulated terminal top is provided with electrical appliance module, the opposite side of the frame corresponding with electrical appliance module is provided with current transformer, frame top is provided with vacuum protective plate, in frame, be provided with relay, relay is provided with plug, and current transformer below is provided with rc absorber.
Described isolating switch is fixed on isolating switch mounting panel, and isolating switch mounting panel is fixed on casing, and advantage is to locate isolating switch, is convenient to dismounting.
Described switch handle, is all provided with flameproof joint on scram button and deadlock lever, advantage is the methane in the spark ignition mine that prevents from producing when switch closed and disconnected, sets off an explosion, and strengthens usage safety performance.
Adopted above-mentioned scheme, operating handle can play the effect of locking door closure, and skid can facilitate its carrying, by skid, slides, and reduces on the one hand the friction on casing itself and ground, thereby protects casing itself, on the other hand can be so that the dismounting of casing; Wire connection cavity and axial outlet wire mouth and radial outgoing wire mouth provide the space of the wire of connection in casing, prevent that wiring is mixed and disorderly, and winding is killed, so that later maintenance, and can also be conveniently and the connection of other devices; Switch handle is connected and can be facilitated its assembling by shaft coupling with isolating switch, being convenient to switch handle rotates, convenient operation, emergency stop switch plays time-lag action on the one hand, also can in case of emergency stop machine work on the other hand, guarantee fail safe, deadlock lever can play the locked at an arbitrary position effect of handle, improves security performance.
