Embodiment
Below in conjunction with accompanying drawing, the present invention is done further and explain.
the present invention includes as Fig. 2: CD air switch (1), ZB1 closing coil pressure regulator (2), ZB2 is under-voltage coil pressure regulator (3), ZB3 shunt opening coil pressure regulator (4), BK auxiliary supply transformer (5), ZJ1, ZJ2, ZJ3 auxiliary reclay (6), 1QA closing coil power supply switch knob (7), 1TA closing coil power supply opening button (8), 2QA is under-voltage coil power switch knob (9), coil power opening button that 1TA is under-voltage (10), 3QA shunt opening coil power switch knob (11), 3TA shunt opening coil power opening button (12), LED1, LED2, LED3 auxiliary contact pilot lamp (13), V1, V2, V3 voltage table (14), A1, A2, the A3 reometer, current-limiting resistance R(16), 1HD power light (17).The present invention has more and is a kind of isolating switch detecting instrument, adopt Winding Single Phase Capacitance, by the combined floodgate of regulating regulated power supply ZB1 closing coil pressure regulator (2), ZB2 is under-voltage coil pressure regulator (3), ZB3 shunt opening coil pressure regulator come the test both opens device, separating brake, overvoltage, under-voltage, auxiliary contact deciliter etc. function, by test circuit come the major loop of test both opens device and auxiliary contact whether closed intact.At first connect power supply 1,2 and the connecting line 3,4,5,6,7,8,9,10,11,12,13 of experimental apparatus and isolating switch.When the CD air switch (1) that closes, the bright indication power supply of 1HD power light (17) is connected, reference voltage Table V 1, V2, V3 are regulated ZB1 closing coil pressure regulator (2), ZB2 is under-voltage coil pressure regulator (3), ZB3 shunt opening coil pressure regulator (4) reach the rated voltage of breaker coil, press the under-voltage coil power switch knob of 2QA (9), under-voltage coil get electric after, reometer V2 should have electric current indication; Press 1QA closing coil power supply switch knob (7), isolating switch should reliably close a floodgate, and auxiliary contacts of circuit breaker is closed, LED1, and LED2, LED3 auxiliary contact pilot lamp (13) is bright; Press 3QA shunt opening coil power switch knob (11), isolating switch is separating brake rapidly, LED1, and LED2, LED3 auxiliary contact pilot lamp (13) change does not work; Press 3TA shunt opening coil power opening button (12) and disconnect the shunt opening coil power; Under "on" position, by regulating the under-voltage coil pressure regulator of under-voltage coil power ZB2 (3) regulation voltage, can measure the under-voltage function of isolating switch.
The present invention now has been applied in ZN-1000A/1140 vacuum circuit breaker, the check of ZN8-630/12.5 high-pressure vacuum breaker, detection.
The above is only the preferred embodiment of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
