The double-line fast switch magnetic starter comprises a main loop and a control loop, the main loop comprises three-phase supply X1, X2 and X3, a separating change-over switch HGK, normally open contacts CKJ11 and CKJ21 of a vacuum contactor, a resistance-capacitance absorption device RC, electric motor comprehensive protectors JDB1 and JDB2 and wiring cavities of the starter D1, D1 and D3. The control loop comprises a control transformer KB, relays ZJ1 and ZJ2, a fuse protector RD1, fuse protectors RD2 and RD3, vacuum contactors CKJ1 and CKJ2, a stop button TA, electric motor comprehensive protectors JDB1 and JDB2 and a selector switch. When one line breaks down, the double-line fast switch magnetic starter can fast shift to a second loop by turning the micro change-over switch on the outer shell of the starter, the starter is enabled to work continuously, fault handling time is greatly shortened, the influence to the coal production is reduced, and production efficiency and production effect are improved.

Description

The quick switch in magnetic force starter of two-way

Technical field

The present invention relates to a kind of magnetic starter, particularly the quick switch in magnetic force starter of a kind of two-way.

Background technology

For coal mining enterprise, safety in production is very important, but the coal production target pursued of enterprise especially.Yet electric fault is a key factor that affects coal production, and the magnetic starter fault has accounted for again the significant proportion of electric fault.The magnetic starter of colliery use at present is all single loop work, parts break down, starter just can not normally move, when breaking down, because conditions down-hole limit and many factors cause troubleshooting slow, few person needs the many person's needs of dozens of minutes several hours, has had a strong impact on the raw coal production in colliery.Particularly some important facilities, equipment, as water pump, blower fan, conveyer etc. will be in case after breaking down, if can not in time resume operation rapidly, will cause serious safety in production consequence.

Summary of the invention

The present invention has overcome deficiency of the prior art, the magnetic starter that provides a kind of two-way to switch fast.

technical scheme of the present invention is: the quick switch in magnetic force starter of a kind of two-way, comprise major loop and control loop, described major loop comprises three phase mains X1, X2, X3, isolation reversing switch HGK, normally opened contact CKJ11 and the CKJ21 of vacuum contactor, resistance-capacitance absorption device RC, comprehensive protector of motor JDB1 and JDB2, the wire connection cavity D1 of starter, D2, D3, three phase mains X1 in described major loop, X2, X3 is by isolation reversing switch HGK, contactor normally opened contact CKJ11 and the CKJ21 of two-way parallel connection, two comprehensive protector of motor JDB1 and JDB2 export the D1 of starter wire connection cavity to, D2, the D3 binding post,

Described control loop comprises control transformer KB, relay ZJ1 and ZJ2, insurance RD1, fuse RD2 and RD3, vacuum contactor CKJ1 and CKJ2, stop button TA, comprehensive protector of motor JDB1 and JDB2 and diverter switch, control transformer KB primary coil in described control loop is connected with power supply X2, X3 through insurance RD1, two independent 36v of transformer output, its common port connects No. 9 binding posts of wire connection cavity through stopping button TA; A road of described control loop is connected with the binding post 2 of wire connection cavity through fuse RD2, protector JDB1, interlocking contact ZJ22, intermediate relay ZJ 1, diverter switch K; Be connected with 9 lines of wire connection cavity through auxiliary contact CKJ22, the contactor CKJ1 of contact ZJ11, contactor CKJ2 simultaneously; Be connected to simultaneously No. 8 binding posts of wire connection cavity; Another road is connected with 1 line through fuse RD3, protector JDB2, chain contact ZJ12, change over switch K, and 9 lines through ZJ21, chain contact CKJ12, contactor CKJ2 wire connection cavity are connected simultaneously; Be connected to start button QA and self-insurance contact CKJ13, CKJ23 between 1#, 2# line; Be connected to contact CKJ14, the CKJ24 of two parallel connections between 11#, 13# line, be connected to contact CKJ15, the CKJ25 of two series connection between 12#, 14# line; Through normally closed contact CKJ16, CKJ26, ZJ13, ZJ23 and diverter switch K, the 33# detection terminal with protector JDB1 and JDB2 is connected the detection line of leak detection relay respectively by the X3 of major loop.

Described diverter switch is miniature change over switch K, realizes the switchover operation of two-way controller, and K is connected in the adhesive loop of the auxiliary relay of two-way controller; Simultaneously, K also is used for the switching of two-way leakage detecting circuit.

Beneficial effect of the present invention is:

When riches all the way when giving birth to fault, can by stirring the miniature change over switch that is arranged on the starter shell, switch to fast second servo loop, starter is worked on, greatly shorten fault handling time, reduced the impact on coal production, improved production efficiency and productivity effect.

Description of drawings

Embodiment

The invention will be further described below in conjunction with accompanying drawing:

as shown in Figure 1, the quick switch in magnetic force starter of a kind of two-way, comprise major loop and control loop, described major loop comprises three phase mains X1, X2, X3, isolation reversing switch HGK, normally opened contact CKJ11 and the CKJ21 of vacuum contactor, resistance-capacitance absorption device RC, comprehensive protector of motor JDB1 and JDB2, the wire connection cavity D1 of starter, D2, D3, three phase mains X1 in described major loop, X2, X3 is by isolation reversing switch HGK, contactor normally opened contact CKJ11 and the CKJ21 of two-way parallel connection, two comprehensive protector of motor JDB1 and JDB2 export the D1 of starter wire connection cavity to, D2, the D3 binding post,

As shown in Fig. 1, operation principle of the present invention is as follows:

When starting working, the change over switch K that is located at controller housing is chosen in 1, short circuit 2#-9# binding post makes the first loop works.

When isolating switch HGK closes; control transformer gets electric, and comprehensive protector of motor JDB begins to motor and the detection of insulating of load circuit, if insulate requirement up to specification; JDB1 (41-31) and the conducting of JDB2 (42-32) junction closure is for the startup of switch provides necessary condition.

When needs start, press QA, the 36v power supply is through RD2-JDB1 (41-31)-ZJ22-ZJ1-K-QA-2#-9#-TA-36V, so ZJ1 gets electric adhesive, the adhesive loop of the closed connection of its normal opened contact ZJ11 contactor CKJ1, main contacts CKJ11 is closed, connect major loop, motor gets electric operation.ZJ12 and CKJ12 disconnect the adhesive loop of second servo loop ZJ2 and CKJ2 simultaneously, do not make its error starting; ZJ13 and CKJ16 disconnect leakage detecting circuit, prevent that high voltage source from sealing in infringement and detecting the loop; CKJ13 is closed, and the self-keeping circuit of turn on-switch is remained in operation equipment.

If in the first loop, certain original paper breaks down, when causing switch not start, the toy trumpet mouth helmet of only need outwarding winding is stirred toggle switch K, makes it to be transformed into 2, so just switches on the No. the second controller to work on.

The operation principle of the No. the second controller is identical with the first loop.
