Description
Technical field
The utility model relates to isolating switch, refers to particularly a kind of isolating switch three-phase proving installation same period for detection of the closing of isolating switch, separating brake.
Background technology
The closing of isolating switch, separating brake synchronism are isolating switch very important parameters in service, and GB GB1984 and JB/T3855 make specific requirement and be≤2ms to this.The maintenance of isolating switch must be tested and adjust its synchronism.But, existing breaker tester just to isolating switch close, the mechanical property parameter of separating brake synchronism tests, and so not only affect measuring accuracy, and cost is also very high.
Summary of the invention
The purpose of this utility model is exactly that a kind of simple in structure, measuring accuracy is high, cost the is low isolating switch three-phase proving installation same period will be provided.
For achieving the above object, the isolating switch three-phase proving installation same period that the utility model is designed, comprise that power supply UC, switch S, time relay coil SJ, three thyristor control units, three light emitting diode D, described three thyristor control units and three light emitting diode D distinguish one by one corresponding series connection formation three road branch roads, described time relay coil SJ and three road branch circuit parallel connections, described power supply UC is in parallel with time relay coil SJ by switch S.
Further, described thyristor control unit comprises time relay contact SJD, breaker contact point A, thyristor G, the anode of described thyristor G links to each other with time relay contact SJD one end, the described time relay contact SJD other end consists of the closed-loop path by the gate pole of breaker contact point A and thyristor G, and the negative electrode of described thyristor G links to each other with light emitting diode D.
Further, power supply UC is rechargeable battery.Like this, can be easy to carry.
Compared with prior art, the utility model has the advantage of: the designed isolating switch three-phase proving installation same period is simple in structure, cost is low, can improve measuring accuracy and testing efficiency.
Description of drawings
Fig. 1 is a kind of circuit theory schematic diagram of the isolating switch three-phase proving installation same period.
Fig. 2 is isolating switch three-phase proving installation same period panel schematic diagram.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
The isolating switch three-phase proving installation same period shown in the figure, comprise that power supply UC, switch S, time relay coil SJ, three thyristor control units 1, three light emitting diode D, three thyristor control units 1 and three light emitting diode D distinguish one by one corresponding series connection formation three road branch roads, time relay coil SJ and three road branch circuit parallel connections, power supply UC is in parallel with time relay coil SJ by switch S.Thyristor control unit 1 comprises time relay contact SJD, breaker contact point A, thyristor G, the anode of thyristor G links to each other with time relay contact SJD one end, the time relay contact SJD other end consists of the closed-loop path by the gate pole of breaker contact point A and thyristor G, and the negative electrode of thyristor G links to each other with light emitting diode D.Power supply UC selects rechargeable battery.
The principle of work of this device is such: Closing Switch S plugged UC, and breaker closing, when breaker contact point A and time relay contact SJD are closed, the gate pole conducting of thyristor G, light emitting diode D can be lit; After the time relay coil SJ energising, add in the 2ms in the isolating switch response time, if light emitting diode D is not lit, then illustrating this phase same period not needs the adjustment isolating switch.
During the test both opens device, two combined floodgate links, 2 usefulness wires are connected to the two ends of switch S, three pairs of isolating switch links, 3 usefulness wires are connected on breaker contact point A and the relay contact SJD, three light emitting diode D observably are embedded on the bulb installation position 5 of panel 4 and get final product.
