Abstract
The invention relates to an impact-resistant and vibration-resistant release for a medium-voltage breaker. The release is characterized by comprising a movable component capable of moving vertically automatically and a balancing component capable of moving vertically under vibration. An impact end of the movable component is used for impacting a bending plate on a release half shaft of the breaker to enable the breaker to be opened, and the other end of the movable component is connected with the balancing component through a balancing bar. The balancing bar can rotate around a connection point where the balancing bar is connected with the balancing component, a guide bar is arranged in the middle of the balancing bar in a penetrating mode, and a stop piece is arranged at the top end of the guide bar. When the balancing bar is contacted with the stop piece, the movable component stops moving upwards under the holding of the balancing component, and the impact end of the movable component is separated from the bending plate on the release half shaft of the release. The impact-resistant and vibration-resistant release has the advantages that the movable balancing component is added on the release, so that the release is provided with impact resistance and vibration resistance, and special requirements of ship environments are met.
Description
Technical field
The present invention relates to a kind of shock-resistant and medium voltage breaker release of vibration resistance, belong to middle pressure technical field of electric appliances.
Background technology
Medium voltage breaker mainly bears the use of the overload of distribution line and power consumption equipment, under voltage, short-circuit protection.Release is as a kind of annex of medium voltage breaker, and implement the actuator that circuit breaker disconnects when circuit occurs short circuit, transships or receives separating brake instruction, it comprises shunted exciter tripping, overcurrent release and under voltage dropout etc.
Existing release on medium voltage breaker, still do not possess performance that is shock-resistant, vibration, under the intense impact residing for boats and ships and vibration environment condition, its version of release easily produces misoperation, makes circuit breaker cisco unity malfunction.
Summary of the invention
The object of this invention is to provide a kind of shock-resistant and release of vibration resistance.
In order to achieve the above object, technical scheme of the present invention there is provided a kind of shock-resistant and vibration medium voltage breaker release, it is characterized in that: comprise the mobile component that can independently move up and down with at the balanced component be hit and can move up and down under vibrating, the bent plate of shock end on the dropout semiaxis clashing into circuit breaker of mobile component, make the normal separating brake of circuit breaker, the other end of mobile component is connected with balanced component by balancing pole, balancing pole can rotate around the tie point of itself and balanced component, guide rod is equipped with at the middle part of balancing pole, the quality of mobile component and mobile component to the product of the torque of center of pilot equals the quality of balanced component and the balanced component product to the torque of center of pilot, stop part is provided with on the top of guide rod, by stop part limiting balance bar impact and under vibration on the displacement that moves, when balancing pole touches stop part, mobile component stopping under the pining down of balanced component moves upward, it clashes into end throws off with the bent plate on the dropout semiaxis of circuit breaker.
Preferably, described mobile component comprises dynamic iron core, back-moving spring and coil is had at dynamic iron core overcoat, dynamic iron core is driven to move upward after coil electricity, dynamic iron core is driven to move downward by back-moving spring after coil losing electricity, the top of dynamic iron core is the push rod of the bent plate on the dropout semiaxis for clashing into circuit breaker, and its bottom is connected with described balancing pole.
Preferably, described balanced component to be located on support and can be moved up and down thereon, and the side of support stretches out and forms described stop part.
The present invention devises a kind of dynamic balancer, makes mobile component and balanced component formative dynamics balance.When normally working, the upper and lower proper motion of mobile component, and balanced component keeps motionless, makes release normally work not by the interference of balanced component motion; When running into intense impact, vibration, mobile component and balanced component, by pay-as-you-go operation, avoid mobile component to strike dropout semiaxis, thus avoid release and produce misoperation because being subject to shock and vibration.
Advantage of the present invention is: by increasing dynamic balancer to release, making release be provided with performance that is shock-resistant and vibration resistance, meeting the special requirement of ship environment.
Accompanying drawing explanation
Fig. 1 is the structural representation of medium voltage breaker release of a kind of shock-resistant and vibration provided by the invention.
Embodiment
For making the present invention become apparent, hereby with preferred embodiment, and accompanying drawing is coordinated to be described in detail below.
As shown in Figure 1, the medium voltage breaker release of a kind of shock-resistant and vibration provided by the invention, comprises balancing pole 1, dynamic iron core 2, coil 3, push rod 4, support 5, stop part 6, balanced component 7, fixed head 8, rotating shaft 9 and guide rod 10.
Structural relation between above-mentioned parts is: dynamic iron core 2 is enclosed within coil 3, and its top is push rod 4, and after coil 3 is energized, dynamic iron core 2 moves upward; After dead electricity, dynamic iron core 2 moves downward by back-moving spring.Dynamic iron core 2 is coupled together by the fixed head of below and rotating shaft and balancing pole 1.Guide rod 10 is riveted on the stop part 6 of support 5 through the long lumbar hole in the middle part of balancing pole 1.Balanced component 7 is arranged in the circular hole of support 5, can move up and down along support 5, and is coupled together with balancing pole 1 by the fixed head 8 of below and rotating shaft 9.The quality of balanced component 7 on the right side of the quality of mobile component that left side is made up of dynamic iron core 2 and push rod 4 and mobile component to the product of the torque at guide rod 10 center equals and the product of the torque at balanced component 7 to guide rod 10 center, make to form dynamic balance structure between balanced component 7 and mobile component.
Operation principle of the present invention is: 1. during normal running: iron core 2 is moved in coil 3 adhesive in energising situation, dynamic iron core 2 moves upward, drive the left end of balancing pole 1, with rotating shaft 9 for fulcrum moves upward, and balanced component 7 remains on original position, the push rod 4 of dynamic iron core 2 upper end clashes into the bent plate on the dropout semiaxis of circuit breaker, makes the normal separating brake of circuit breaker.After coil 3 dead electricity, dynamic iron core 2 down moves by back-moving spring and realizes resetting.2. when there is intense impact, vibration, dynamic iron core 2 and balanced component 7 are subject to the effect of power all simultaneously, can move upward simultaneously, at stop part 6, be obstructed in place, because both sides are in dynamic equilibrium, now dynamic iron core 2 is subject to pining down of balanced component 7 and can not continues to move upward, and push rod 4 does not contact the bent plate of de-mouth semiaxis, avoid push rod 4 clash into the bent plate of de-mouth semiaxis and cause circuit breaker misoperation, thus solve release because producing the technical problem of misoperation by thump.
