Description
Technical field
The utility model relates to a kind of electrical device, especially detects the device of vacuum circuit breaker handcart quality.
Background technology
Must join cabinet after circuit breaker cart assembling is in the past finished does test and could verify whether its spaced apart, die opening and secondary connection etc. meet the demands.And join the cabinet test a lot of weak points are arranged also, as circuit breaker cart shake into whether the dynamic/static contact contact smooth and easy in the middle of the process, whether the position aligns, stressed whether evenly, how much mesh size etc. and all can't observe clearly, whether the contact wiring of isolating switch correctly can not come into plain view; Whether correct, spare contact is manual measurement one by one then if can only test out the contact wiring of using in the switch cubicle secondary circuit in the middle of switch cubicle, workload is lost time greatly again, nor can detect the correctness of circuit breaker cart wiring fully; In addition, the contact of not using in the switch cubicle secondary circuit just can't judge whether its wiring is correct, so isolating switch is joined cabinet and done test significant limitation arranged.
The utility model content
Technical problem to be solved in the utility model provides a kind of device that detects vacuum circuit breaker handcart quality, and this device should be able to overcome the deficiency of above-mentioned background technology, have detection quick and precisely, automaticity height, characteristics that working strength is low.
The technical solution adopted in the utility model is: the device of a kind of fast detecting vacuum circuit breaker handcart assembling and wiring correctness comprises the plurality of detection instrument, testing circuit and the control box that are installed on the framework; It is characterized in that this device comprises that also two are horizontally set on handcart guide rail on the framework, vertically are installed in the instrument display board on the framework and be installed in some static contacts on the instrument display board; Above-mentioned measuring instrument, static contact are connected described testing circuit respectively.
The position is corresponding one by one for some Mume flower contacts on described some static contacts and the vacuum circuit breaker handcart.
Described handcart guide rail is to the locus between some static contacts, and mate mutually the wheel on the vacuum circuit breaker handcart to the locus between the Mume flower contact.
Described two handcart guide rails are horizontally fixed on the left and right sides of frame mid portion.
The beneficial effects of the utility model are: this device can verify fast whether the circuit breaker cart fitted position is accurate, and the signal lamp on the pick-up unit can reflect clearly whether all contact wiring are correct; Only need energized (power supply type can be selected arbitrarily according to the power supply of isolating switch), circuit breaker cart shaken from testing position enter the working position, just can disposable its every function that detects whether meet design requirement, finish the check of isolating switch fast and accurately; Be to join 1/20th of cabinet proving time proving time of an isolating switch.In addition, because the automaticity height, detection is light, convenient, thereby has significantly reduced the intensity of testing.

Embodiment
As shown in the figure, the framework 1 of this pick-up unit all is welded by angle steel, and two handcart guide rails 2 are horizontally fixed on the left and right sides (as shown in Figure 1) of frame mid portion; Framework upper has vertically been installed instrument display board 5, is provided with several static contacts 3 (having shown six static contacts among the figure) above the instrument display board, and some Mume flower contacts 11 of these static contacts and circuit breaker cart 10 are the corresponding and coupling in position one by one.Testing circuit is connected measuring instrument and static contact respectively.Also be provided with the signal lamp 6, on/off switch button, energy storage button of monitoring secondary contact etc. on the instrument display board, signal lamp and number of buttons are corresponding with the quantity of breaker contact point, and each signal lamp all has label to reflect that the contact of its representative numbers.The underframe left surface is provided with secondary line and draws the aviation socket.Secondary circuit is connected, disconnects very convenient.After the isolating switch assembling was finished, to the guide rail of pick-up unit, isolating switch was positioned at the testing position of pick-up unit automatically with transhipment handcart amplifier.After secondary circuit was connected, circuit breaker cart shook from testing position and enters the working position, the Mume flower contact 11 of circuit breaker cart 10 just accurately pegs graft with static contact 3 (chuck 112 clamps the outer wall of static contact 3 under spring 111 effects simultaneously, to guarantee that grafting reliably); Every technical indicator of isolating switch just shows by measuring instrument (comprising A.C. voltmeter, D.C. voltmeter), can verify every technical indicator of vacuum circuit breaker handcart quickly and easily, and simple in structure, not yielding, the practicality height.
Testing circuit is installed in the control box, principle of work mainly is that each function of isolating switch such as closing circuit, sub-gate circuit, tank circuit and other auxiliary node are connected in series a pilot lamp (as shown in Figure 5) respectively by the module in the control box, and energized is verified the correctness of assembling of vacuum circuit breaker handcart and wiring by the state of pilot lamp.The detection principle is as follows:
Because the energy storage motor of isolating switch is an AC/DC universal, touch energy storage switch CN behind the introducing power supply, tank circuit S1 is logical, can be to the isolating switch energy storage, the energy energy storage is normal with regard to the tank circuit of decidable isolating switch; The on/off switch coil of isolating switch is then changed by switch KK by pressure regulator TYQ and diode ZP mutually according to different voltage types and electric pressure, its voltage type and electric pressure can show by voltage table V1, V2 (being respectively D.C. voltmeter and A.C. voltmeter), touch combined floodgate switch HZ after adjusting voltage, closing circuit Y9 is logical, can be to breaker closing, it is normal with regard to the closing circuit of decidable isolating switch to close a floodgate; The same separating brake switch FZ that touches, sub-gate circuit Y1 is logical, can be to breaker open operation, the energy separating brake is normal with regard to the sub-gate circuit of decidable isolating switch; At the isolating switch on/off switch simultaneously, its signalling contact QF can corresponding switching, and ((D1～Dn), the working condition of pilot lamp just can be judged each signalling contact to the pilot lamp of corresponding serial connection of QF1～QFn) each signalling contact.Thereby reach the correctness of quick checking vacuum circuit breaker handcart wiring.
Among Fig. 5 also as can be known: be connected in series discharge cock 1RD and discharge cock 2RD on phase line L and the zero line N respectively; Switch KK is provided with each wiring point a, b, c, d, e, f, g, h.
