Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure: 1, power supply box; 2, the first closing line; 3, the first separating brake circuit; 4, the second closing line; 5, the second separating brake circuit; 6, moving contact; 7, stationary contact; 8, energy accumulation output device.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection domain of the present utility model.
Switching characteristic analyser as a kind of in Fig. 1, comprise power supply box 1, power supply box 1 connects the first closing line 2 and the first separating brake circuit 3, first closing line 2 connects the second separating brake circuit 5, first separating brake circuit 3 connects the second closing line 4, power supply box 1 is provided with energy accumulation output device 8, when needs do combined floodgate test, only the moving contact 6 in the second separating brake circuit 5 need be contacted with stationary contact 7, the closing time to switch can be realized, speed is tested, simultaneously can the spring process of Test Switchboard, during as separating brake test need be done, only the moving contact 6 in the second closing line 4 and stationary contact 7 need be disconnected, can realize moving contact 6 and stationary contact 7 trip time and velocity test, in power supply box 1, power supply connects power supply or external synchronous input power in being, can need to connect power supply or adopt external synchronous input power in selection according to field demand or client self, first closing line 2, first separating brake circuit 3, second closing line 4 and the second separating brake circuit 5 include moving contact 6 and static contact 7, moving contact 6 and static contact 7 are all graphite contacts.
This switching characteristic tester has breaker energy storage, the test of breaker closing resistance value and making time test, and above-mentioned technical indicator is all important indicators of switch.
Breaker energy storage is undertaken by switching characteristic analyser itself, after switch has closed a floodgate, internal electric source carries out the energy storage to switch, internal electric source provides the output of direct supply 15A, 10S, maintained switch energy storage is mated completely with the power of motor, and record energy storage time, support external energy storage, power supply or directly energy storage is carried out to switch with instrument direct supply simultaneously, breaker closing resistance value test, be moving contact contact with stationary contact close after, utilize multimeter to test the resistance between moving contact and stationary contact, to know resistance value therebetween, add a technical indicator of switch, switching accuracy is improved, ensure that the quality of switch, making time is tested, improve the judgement precision of switch, the main conjunction time from energization control signal (coil powers on) received by switch to switch movable contact and static contact first time close the time, the auxiliary conjunction time closes the time (input) to reclosing resistance switchgear first time from energization control signal (coil powers on) received by switch, the pre-cast time refers to the switching-on resistance operational use time, from the auxiliary conjunction time to the time period of main conjunction time, gold (dividing) time of closing is the time from conjunction (dividing) lock control signal (coil powers on) received by switch to switch movable contact closes (separating) with static contact (metallic member) first time, (dividing) the lock time of conjunction contacts (beginning arc extinguishing) or point ETAD expected time of arrival and departure to graphite nozzle from conjunction (dividing) lock control signal (coil powers on) received by switch, quenching time refers to the graphite arc extinguishing operational use time, the time period of (dividing) time is closed from (dividing) the lock time of conjunction to gold.
It is emphasized that: the foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model instructions and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
