Description
Technical field
The utility model relates to isolating switch three-phase synchronism tester, is exclusively used in the closing of test both opens device, separating brake synchronism.
Background technology
The closing of isolating switch, separating brake synchronism are very important parameters during isolating switch is produced, and GB GB1984 and JB/T3855 have made concrete requirement≤2ms to this, and must there be this test event in all isolating switch manufacturers when delivery test.
The production of existing isolating switch is to be assembled by rule of thumb by the workman earlier, again it is moved at last on the test station with the isolating switch tester go to test it comprise close, a series of mechanical property parameters of separating brake synchronism.When finding to close, when separating brake synchronism parameter does not meet standard, must be restored to the production station and go to adjust, the number of occurrence is more, can influence the production and the testing efficiency of product, and the running of obstruction streamline is smooth and easy.And the isolating switch tester is the comprehensive tester of all mechanical properties of test both opens device, can not be equipped with producing on the station, and reason has two: one, drop into more uneconomical, the 2nd, the isolating switch tester also need be equipped with power supply, takies the streamline space.
So a kind of test both opens device closes, the simple instrument of separating brake synchronism if can develop, be fit to each isolating switch manufacturer and on the production station, dispose, vast market prospect must be arranged.
Summary of the invention
The utility model purpose provides a kind of isolating switch three-phase synchronism tester, and the test both opens device closes on the production station to satisfy, the needs of separating brake synchronism.
For achieving the above object, the technical solution adopted in the utility model is: a kind of isolating switch three-phase synchronism tester, comprise three Led lamps, three pairs of isolating switch links, a switch and power supplys, three Led lamps and three pairs of isolating switch links connect one to one and constitute three road branch roads, this three road branch road is in parallel and picks out first, second two and tie-point, first and tie-point connect power supply one end through switch, second and tie-point connect the other end of power supply; Described three pairs of isolating switch links are for three pairs of main contactss that connect isolating switch to be tested.
Related content in the technique scheme is explained as follows:
1, in the such scheme, also can comprise an on-delay type time relay, the normally closed contact of this on-delay type time relay be serially connected in first and tie-point and switch between, and coil one end of the on-delay type time relay and the end that is connected with on-delay type time relay normally closed contact to described switch, the other end of the coil of the on-delay type time relay and to second tie-point also.The application of the on-delay type time relay is played the function of automatic outage, to avoid the unnecessary consumption of power supply.
2, in the such scheme, also can comprise six roots of sensation flexible circuit conductor, an end of every flexible circuit conductor is established plug, and the other end is established crocodile clip; Three pairs of isolating switch links are through the three pair main contactss of six roots of sensation flexible circuit conductor for connection isolating switch to be tested.
3, in the such scheme, described power supply is a rechargeable battery, also can charge to it by charger with this conveniently moving.
Principle of work of the present utility model is: the utility model is configurable to be produced on the station at isolating switch, and the workman can use the utility model test when the assembling isolating switch.During use, three pairs of main contactss of isolating switch to be tested are connected on three pairs of isolating switch links, even each main contacts of isolating switch is together in series with the Led lamp is corresponding, press the switch connection power supply then, this moment, its corresponding Led lamp can be lighted when each main contacts of isolating switch was closed with breaker closing to be tested.The workman adjusts corresponding site in the isolating switch by the light on and off order and the time interval of observing three Led lamps, thus dwindle as far as possible close, the separating brake time same period, with synchronism control within limits.
Effect of the present utility model is: the utility model is simple in structure, volume is little, cost is low, be suitable on isolating switch production station, disposing, thereby the foundation that can in the process of producing station assembling isolating switch, provide main contact to adjust to the workman, ensured to a certain extent that isolating switch closes, the adjusting to the right place of separating brake synchronism, produce coming and going between station and test station thereby reduce isolating switch, improve the production and the testing efficiency of isolating switch.
