Abstract
The utility model provides a dual-supply automatic transfer switch including a base, a foundation support, a transfer mechanism and two circuit breakers. The transfer mechanism includes a motor, a cam installed on a motor spindle fixedly, two transmission rods separately installed on a rotary shaft of the foundation support in a rotary manner and are arranged to be in mirror symmetry around the motor spindle. Two sides of the cam are provided with arc-shaped limiting gaps that are in mirror symmetry around the motor spindle. One ends of the transmission rods that are adjacent to the motor are provided with bearings fixedly while the other ends of the transmission rods that are far away from the motor are provided with stir ports. Handles of the two circuit breakers are respectively installed in the stir ports of the transmission rods in a sleeved manner. The bearings can slide in the corresponding limiting gaps in a cam rotation process and drives the transmission rods to rotate around the spindle. An upper end face of each of the stir ports is provided with a slide board fixedly. Limiting pieces are arranged on the slide board and on two sides of the handle of the corresponding circuit breaker respectively. And a distance between the two limiting pieces is smaller than an opening distance of the handle of the corresponding circuit breaker. The dual-supply automatic transfer switch provided by the utility model has a beneficial effect that service lifetime of the dual-supply automatic transfer switch can be improved effectively.
Description
Technical field
The utility model is specifically related to a kind of double power supply automatic transfer switch.
Background technology
At present, there are very high requirement in many industries and department to the reliability of power supply, and in order to guarantee the continuity of power supply, it is electric power supply that many important occasions all adopt double power supply automatic transfer switch.The double power supply automatic transfer switch of existing translator interlocking is all by the driven by motor dial rotation, and the driving lever of driven by rotary disc both sides rotates, and the other end of two driving levers promotes respectively circuit breaker handle and realizes dividing, closing a floodgate, and reaches the effect of duplicate supply switching.Yet the driving lever of existing double power supply automatic transfer switch is all metallic article, and circuit breaker handle is plastic part, when the driven by motor driving lever rotates the moment that promotes the circuit breaker handle divide-shut brake, contact-making surface between driving lever and circuit breaker handle is little, driving lever is very large to the pressure of circuit breaker handle, thereby when switching, driving lever is easy to damage circuit breaker handle, greatly reduces useful life at double power supply automatic transfer switch.
Summary of the invention
The purpose of this utility model is to overcome the defect of prior art, provides and can effectively improve the double power supply automatic transfer switch in useful life.
For achieving the above object, the utility model adopts a kind of double power supply automatic transfer switch, comprise base, pedestal, switching mechanism and two circuit breakers that are arranged on the switching mechanism both sides, described switching mechanism comprises motor, be fixedly mounted on the cam on machine shaft, in two rotating shafts that are rotatably installed in respectively pedestal and be symmetrical in the drive link that machine shaft arranges, the bilateral symmetry of described cam is provided with the arc-shaped limit breach in machine shaft, each drive link is fixedly installed respectively bearing near an end of motor, each drive link is provided with group mouth away from an end of motor, two circuit breaker handles are set in dialling in mouth of drive link, each bearing can be along with in the cam rotation process, in corresponding spacing breach, slide, and the drive drive link rotates around the axis, the upper surface of described group of mouth is fixedly installed slide plate, be positioned at place, circuit breaker handle both sides on slide plate and be provided with respectively locating part, and the spacing of two locating parts is less than the divide-shut brake of circuit breaker handle and opens distance.
Preferably, described locating part comprises rivet and slide block, and slide block is movably riveted on described slide plate by rivet, and slide plate can rotate around rivet.
In such scheme, when drive link promotes the circuit breaker handle divide-shut brake, mouthful place of dialling on described drive link is provided with rotating slide block, the lifting to maximum area of the contact-making surface of slide block and circuit breaker handle, effectively reduced unit contact pressure, thereby the thrust on the drive link made effectively is carried on slide block, reduced the wearing and tearing to circuit breaker handle, also improved transmission efficiency and smoothness simultaneously.Its beneficial effect is the useful life that has extended product.
Further improvement as the utility model to prior art, be provided with a plurality of installing holes on described slide plate, and each installing hole is all waist-shaped hole.Be set to waist-shaped hole by installing hole, the position of the slide block on slide plate can be adjusted, thereby in the time of can guaranteeing the dual supply operation mechanical unlocking, realizes detaining again.
