The patent No. is the utility model patent of 200420011262.X, discloses a kind of duplicate supply switch controller.The phase shortage that this kind controller has the three phase supply power supply detects and the protection handoff functionality, when normal power source breaks down, can automatically switch to stand-by power supply and continue can carry out anti-switching to electric automatically after power up is normal.Can satisfy the requirement that low-voltage power supply system switches power supply.But the shortcoming of this kind controller is to adopt a large amount of elements such as auxiliary relay, and volume is bigger, and wiring is loaded down with trivial details.
Patent documentation CN201374583Y discloses a kind of double power supply automatic transfer switch, comprises controller, power pack, mechanical switch operating mechanism and commonly used and back-up breaker; Commonly used be connected with the mechanical switch operating mechanism, use power supply and stand-by power supply always and be connected with circuit between the load in order to control with back-up breaker; Controller comprises single-chip microcomputer, drive circuit, voltage-contrast circuit and logic judging circuit, single-chip microcomputer is in order to control Driver Circuit, voltage-contrast circuit and logic judging circuit, and controller monitors power supply commonly used that is moving and the stand-by power supply of preparing to switch; Its mechanical switch operating mechanism comprises a shell, be positioned at the driving cam of shell, be connected with driving cam in order to the motor that drives driving cam, be positioned at the cam both sides with in order to commonly used and standby transmission driving lever, the axis of guide of stirring cam be enclosed within axle sleeve on the axis of guide; Described transmission driving lever is connected with the circuit breaker on both sides, and drive link adopts the shaft type guiding, and the axle sleeve that leads on the driving lever is done along the axis of guide in the mechanism and seesawed to drive breaker closing or separating brake.In addition, this kind mechanical switch operating mechanism closes a floodgate simultaneously in order to prevent two circuit breakers, also locating part is set in driving cam one side, when driven by motor driving cam and transmission driving lever commonly used rotated closing position with circuit breaker when power supply commonly used closes a floodgate, locating part was pushed down standby transmission driving lever it can not be rotated; When stand-by power supply closes a floodgate, when driven by motor driving cam and standby transmission driving lever rotate closing position with back-up breaker, locating part will be used the transmission driving lever always and push down it can not be rotated.The shortcoming of this kind mechanical switch operating mechanism is when realizing the divide-shut brake action, comparatively effort.
The utility model content
The purpose of this utility model provides the divide-shut brake that a kind of comparatively labour-saving is used for dual-power transfer switch and dials plate.
The technical scheme that realizes the utility model purpose is: a kind of divide-shut brake that is used for dual-power transfer switch is dialled plate, and its plate body is provided with the hole clipping that is used to be stuck on the external breaker of plastic casing operating grip; One end of described group of plate plate body is provided with spacing slide opening, and the other end of described group of plate is provided with pin shaft hole.
Described hole clipping is arranged between described spacing slide opening and the pin shaft hole.
Each card is established a working of plastics on the relative two side ends plate body of described hole clipping, and leaves the gap between the adjacent limit wall of two working of plasticss.
The utlity model has positive effect: in (1) the utility model, an end of described group of plate plate body is provided with spacing slide opening, and the other end of described group of plate is provided with pin shaft hole; In concrete the use, the mode that this group plate is stirred external breaker of plastic casing operating grip is: dial plate and back and forth rotate around the bearing pin that passes self plate body pin shaft hole, drive the operating grip divide-shut brake in rotating process.This mode is compared with traditional translation breaking-closing operating mode, and is comparatively laborsaving.
(2) in the utility model, each card is established a working of plastics on the relative two side ends plate body of described hole clipping, and leaves the gap between the adjacent limit wall of two working of plasticss.The advantage of this kind structure is: first, adopt metal to make owing to dial plate more, utilize two gaps between the working of plastics will dial on the operating grip that sleeve-board is connected on external breaker of plastic casing, thus avoid metal material dial plate in long-term the use, damage the operating grip of plastic material; The second, at same group of plate,, can adjust two gap lengths between the working of plastics, thereby make this group plate can adapt to the breaker of plastic casing of multiple different sizes by selecting the working of plastics of different sizes for use.
