Abstract
The utility model relates to a switch and especially relates to a dual-power automatic change-over switch. The dual-power automatic change-over switch comprises a pedestal. Left and right sides of the pedestal are provided with a common circuit breaker and a back-up circuit breaker respectively and a motor is installed in the middle. The motor is equipped with a control support. The control support is provided with a drive plate. The motor is connected with an output shaft. The output shaft passes through the drive plate and is connected through a fixing device. The drive plate is formed by an upper drive plate and a lower drive plate. Four angles of the drive plate are provided with driving levers which are vertical to a drive plate plane respectively. The two driving levers on the left side are a common closing lever and a common separating brake lever. The two driving levers on the right side are a standby closing lever and a standby separating brake lever. The common closing lever, the common separating brake lever, the standby closing lever and the standby separating brake lever are arranged between the upper drive plate and the lower drive plate. Two limited rods which are vertical to the drive plate plane are symmetrically arranged on a central section of the drive plate. The limited rods are arranged below the lower drive plate. Motor micro switches are arranged on operation supports of two sides of the limited rods. The switch of the utility model is connected with the motor through the fixing device so that a switch handle contact effect is good and is stable. Working efficiency is further increased.
Description
Technical field
The utility model relates to a kind of switch, particularly double power supply automatic transfer switch.
Background technology
The automatic turn-off of duplicate supply closes and is widely used in some places that do not allow to cut off the power supply (such as fire-fighting, airport, radio and television, hospital, market, bank, chemical industry, metallurgy, skyscraper and military affairs
Equipment etc.).China's national standard and worker EC standard are divided into PC level and two ranks of CB level with double power supply automatic transfer switch.PC level double power supply automatic transfer switch is merely able to disjunction and connects load, does not possess short circuit and excess current protective function, the general PC level double power supply automatic transfer switch protection component (such as circuit breaker) that needs to increase electric power in distribution line.CB level double power supply automatic transfer switch main body by two open circuit, controlling organization and operating mechanism form; unusual (the outage of controlling organization in can testing circuit; short circuit etc.); and close a floodgate according to the separating brake that unusual condition control operation mechanism finishes circuit breaker; thereby have short circuit and excess current protective function, so function is more comprehensive.
At present, the electronics that the automatic turn-off of duplicate supply is shut does not connect by fixture, and conversion support is easily loosening, causes and the switch knob loose contact, and is unstable, the impact normal operation.
The utility model content
In order to overcome above shortcomings part in the prior art, the purpose of this utility model is to provide a kind of double power supply automatic transfer switch.
In order to reach above-mentioned purpose, the utility model adopts following concrete technical scheme: double power supply automatic transfer switch, comprise base, the described base left and right sides is respectively equipped with circuit breaker commonly used and back-up breaker, motor is equipped with in the centre, and the control support is housed on the described motor, and described control support is provided with driver plate, be connected with output shaft on the motor, output shaft passes driver plate and connects by fixture.
Described driver plate is made of upper driver plate and lower driver plate, four jiaos of driving levers that are respectively arranged with perpendicular to the driver plate plane of driver plate, left side two driving levers are combined floodgate bar commonly used and minute restrictor bar commonly used, right side two driving levers are combined floodgate bar for subsequent use and for subsequent use minute restrictor bar, and combined floodgate bar commonly used, minute restrictor bar commonly used, combined floodgate bar for subsequent use, for subsequent use minute restrictor bar are arranged on up and down between the driver plate.
The middle part of described driver plate is symmetrically arranged with two gag lever posts vertical with the driver plate plane, and gag lever post is arranged on lower driver plate bottom, and the operation support in the gag lever post both sides is provided with the electric motor micro-motion switch.
Compared with prior art, the utlity model has following outstanding advantages and be connected the utility model with effect and connect motor by fixture, make the switch knob contact effective, stable again, further increase work efficiency.
