Abstract
The utility model relates to a circuit breaker overloading or short circuit characteristic detection and test device, which comprises a frame, a positioning equipment, a transmission equipment, a compaction equipment and in addition a close- open brake device. The close-open brake device consists of a cylinder which is provided with a dual-electronic control valve, magnetic sensors, a close-open brake slot and a guideway; wherein the cylinder which is provided with a dual-electronic control valve and the guideway are fixed on the frame; the close-open brake slot is fixedly connected with the piston rod of the fixed cylinder on the frame and meshes with the guideway fixed on the frame; the cylinder is provided with three magnetic sensors which are fixed on the cylinder body. Since a plurality of sensors are arranged on one cylinder, the poisoning equipment is simple in structure and low in cost; flexible and accurate positioning at various different places can be realized and incoordination of a plurality of cylinders working synchronously and complex technical problems appeared in the control process can be avoided. More importantly the utility model can greatly reduce the work intensity of the workers, ensure the accuracy of the detection result and improve the detection efficiency.
Description
Affiliated technical field
The utility model belongs to a kind of isolating switch detection and uses test unit, particularly relates to a kind of isolating switch overload or short circuit curve and detects test unit.
Background technology
The present known experiment table that circuit breaker parameters is detected, their primary structure has generally comprised: locating device, conveyer and compress or several parts of clamp device.The workman is fixed on isolating switch on the locating device during test, conveyer by the dolly that slides along guide rail or slide block will be fixed on isolating switch in the locating device on dolly or the slide block and give and enter the detection position then, again by compressing or clamp device compresses isolating switch terminal and test connection terminal or clamp, at last by manually isolating switch being carried out the on/off switch operation to test accordingly.Wherein because the breaker closing separating brake is detained multipoint control of returning meta again, need manually-operated to realize that so not only labor strength is big, and cooperate very difficult the coordination with the measurement of characterisitic parameter, greatly influence the precision that detects, reduced detection efficiency simultaneously.
Summary of the invention
The utility model provides a kind of on/off switch device to detect test unit at the isolating switch overload or the short circuit curve of multiposition flexible positioning for solving the technical matters that exists in the known technology.
The technical scheme that the utility model is taked for the technical matters that exists in the solution known technology is:
It includes framework, locating device, conveyer and the hold down gag of pick-up unit, it also includes the on/off switch device, and described on/off switch device includes cylinder, magnetic sensor, guide rail, the on/off switch draw-in groove that is used to promote tested circuit breaker handle, circuit control device and the gas circuit control device that two electric control valves are housed; Described cylinder and the guide rail that two electric control valves are housed is connected on the framework respectively; Described on/off switch draw-in groove is connected mutually with the piston rod of cylinder on being fixed on the pick-up unit framework, and described on/off switch draw-in groove be fixed on the engagement of sliding mutually of guide rail on the framework, three magnetic sensors are housed on the cylinder body of described cylinder, and three magnetic sensors are separately fixed at two ends and the centre position on the cylinder block.
The utility model can also adopt following technical measures:
Described on/off switch draw-in groove is fixed on the slide block, and described slide block is connected with the piston rod of cylinder on being fixed on the pick-up unit framework, and the guide rail that is fixed on the pick-up unit framework inserts in the groove of slide block.
Advantage and the good effect that the utlity model has are: owing to adopt this locator meams that a plurality of sensors are installed on single cylinder, not only positioning device structure is simple, cost is low, and can be implemented in diverse location flexibly, accurate location, also can eliminate when adopting the multi cylinder synchronous working too complicated technology problem of inharmonious and control procedure.Main is to have alleviated working strength of workers greatly, has guaranteed the precision that detects, and has improved detection efficiency simultaneously.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplifies following the utility model now and be used for the breaker closing separating brake and detain embodiment in multipoint control of returning meta again, and conjunction with figs. is described in detail as follows:
As shown in Figure 1, on/off switch draw-in groove 1 is fixed on the slide block 2 and is connected with the piston rod of cylinder 3 on being fixed on pick-up unit framework 8, and the guide rail 4 that is fixed on the pick-up unit framework 8 inserts in the groove of slide blocks 2; Three magnetic sensors 5,6,7 are housed on the cylinder body of cylinder 3, and magnetic sensor 5,7 is separately fixed at the two ends on cylinder 3 cylinder bodies, and magnetic sensor 6 is fixed on the centre position on cylinder 3 cylinder bodies.
In addition, also can be provided with groove, and will be fixed on guide rail 4 on the pick-up unit framework and insert in the groove that on/off switch draw-in grooves 1 top is provided with on the top of on/off switch draw-in groove 1.
The operational process of cylinder 3 pistons is to be undertaken by three magnetic sensors 5,6,7 of being equipped with on the cylinder body and circuit control device and the control of gas circuit control device.
Its course of work is: the initial position of cylinder 3 is the centre position, and by sensor 6 location, the switch knob that is fixed on the detected isolating switch on the locating device is in the on/off switch draw-in groove 1; Cylinder 3 promotes on/off switch draw-in groove 1 forward, and by sensor 5 location killer switch is closed a floodgate; Drive on/off switch draw-in groove 1 when cylinder 3 is recovered to mid point, make breaker open operation by sensor 6 location; If isolating switch is owing to accident is threaded off this moment, cylinder 3 will continue to regain, and by sensor 7 location isolating switch be detained again; After finishing button, cylinder 3 returns to meta by sensor 6 location, promptly realizes returning meta again.
