Abstract
The utility model provides a high-voltage vacuum contactor with a mechanical controlled on/off switch interlock. Two contactors are installed back to back and connected by an adjustable interlocking lever. Both ends of the interlocking lever are respectively lapped to joint a piece of armature iron on the occasion that one contactor is on position and a piece of armature iron on the occasion that the other contactor is in off position. When one contactor is in electrical switching position, the armature iron of the contactor is used for pushing the interlocking lever to jack off the armature iron of the other contactor, and thus the contactor in off position to reach the forced mechanical interlock between the two contactors. The utility model has the visible advantages of small volume, small using space, no additional force, forced interlock, accuracy and reliability. The needed high-voltage vacuum contactor with reliable mechanical controlled on/off switch interlock in high voltage control equipment is satisfied.
Description
The utility model belongs to the control apparatus device, designs a kind of high-pressure vacuum contactor that machinery control is closed, separating brake is chain that has especially.
In high-tension line, the unlatching that is used for control transformer, high-voltage motor, capacitor group to be to realize the high pressure vacuum device of far distance automatic controlling, is to close to close or the actuator of disjunction high-tension circuit.Therefore, in control procedure, then need in two contactors one to be in "on" position and another must be in the chain of gate-dividing state.This just requires to have reliably between two contactors and closes, the complementary chain control device of separating brake is realized.
Before the utility model, control contactor closes, separating brake and realize the electric or mechanical dual mode of chain general employing, though electrical interlocks possesses simple characteristics on control transformer and high-voltage motor, but it is insecure only relying on electrical interlocks for high voltage control such as submersible electric pumps, in case out of control, can cause the adverse consequences of phase fault.This has just brought certain limitation to the scope of application.And mechanical chain is to install runner on the rotation axis of contactor additional, and the runner of two contactors connects with connecting rod again, and it has not only strengthened rotating torque and has taken up room, and connecting link is many, easy break-down.And exist the manufacturing cost height, and optional chain, the drawback of poor reliability.
The purpose of this utility model is to provide a kind of need expansion to take up room, and volume is little, and globality is strong, resistance is little, forces action, accurately and reliably, connecting rod is adjustable has Machinery Control Console, a chain high-pressure vacuum contactor of separating brake, to overcome the deficiency of prior art in using.
The purpose of this utility model realizes with following technical scheme: have machinery control and close, the high-pressure vacuum contactor that separating brake is chain, have that a determining deviation is back-to-back to be fixedly mounted in two contactors on the same level board and the contactor two solenoid and coil braces side by side, it is characterized in that: be arranged on latch lever between above-mentioned two contactors between two parties and suspend respectively and pass in the contactor side by side in the coil brace hole between the solenoid, one end and the armature overlap joint that is in closing position when a contactor, the other end and the armature overlap joint that is in the separating brake position when another contactor; When one contactor is subjected to electric "on" position, make the armature pushing tow latch lever of a contactor back down the armature of another contactor, make it be in the separating brake position and realize that positive mechanical is chain.
Above-mentioned latch lever is an adjustable latch lever, and it adjusts length is that an end is overlapped on the armature that is in "on" position position contactor just, and the other end is overlapped on the armature that is in gate-dividing state position contactor.
Characteristics of the present utility model are: contacted with the armature of two contactors by latch lever and control that its pass is closed and off-state realizes chain; In addition, because latch lever is to suspend to be installed in the contactor in the coil brace hole, this has just significantly reduced chain additional force.
The advantage that the utility model embodies is: (1) by latch lever contact with the armature of two contactors control that its pass is closed and the off-state realization chain be enforceable, misoperation can not take place, make it accurately and reliably chain.(2) realize that by the body of contactor latch lever installs, need not enlarge and take up room.(3) the latch lever volume is little, and is in light weight, and contactor is not increased moment of face, do not influence the former technical parameter of contactor.
Specify the utility model below in conjunction with drawings and Examples.
Accompanying drawing 1 structural representation of the present utility model.
As shown in Figure 1: a kind of have a high-pressure vacuum contactor that machinery control is closed, separating brake is chain, spacing distance is 100mm, leading-out terminal is at back-to-back two contactors 1,2 that are fixedly mounted on the same level board in the outside, the latch lever 5 that is arranged on the steel material between above-mentioned two contactors 1,2 between two parties suspends respectively and passes in the contactor side by side in 6 holes of the coil brace between the solenoid 7, one end then overlaps with the armature 4 that is in the separating brake position when another contactor with armature 3 overlap joints that are in closing position when a contactor, the other end.Above-mentioned latch lever 5 is adjustable latch levers, it is made up of with the connecting rod that adjusting locknut internal thread coupling is connected adjusting locknut that has internal thread and two ends, it adjusts length is that an end is overlapped on the armature that is in "on" position position contactor just, and the other end is overlapped on the armature that is in gate-dividing state position contactor.
Operation principle is: in two contactors by latch lever phase interconnected lock, when wherein a contactor is subjected to electronic the work, when making solenoid attract the end face of iron core motion of armature in solenoid and the pushing tow latch lever move and it backed down to the armature of another contactor, force it to be in the separating brake position and be not subjected to; On the contrary, when another contactor is subjected to electricity, and the armature pushing tow latch lever of another contactor backs down the armature of this contactor, makes it be between branch the position and realizes that positive mechanical is chain.
The utility model is applicable to and exchanges 50HZ, in the 3-10KV power circuit, for closing and the disjunction circuit far distance automatic pass.
Claims (2)
1, a kind of have a high-pressure vacuum contactor that machinery control is closed, separating brake is chain, have back-to-back solenoid and the coil brace of installing side by side in two contactors on the same level board and the contactor that be fixedly mounted on of a determining deviation, it is characterized in that: be arranged on latch lever between above-mentioned two contactors between two parties and suspend respectively and pass in the contactor side by side in the coil brace hole between the solenoid, one end and the armature overlap joint that is in closing position when a contactor, the other end and the armature overlap joint that is in the separating brake position when another contactor; When one contactor is subjected to electric "on" position, make the armature pushing tow latch lever of a contactor back down the armature of another contactor, make it be in the separating brake position and realize two mechanical chains between contactor.
