Abstract

The invention relates to an impulse withstand voltage testing device for GIS devices of transformer stations. The impulse withstand voltage testing device for the GIS devices of the transformer stations comprises an impulse voltage generating device, power source accessories and a carrying platform. The impulse withstand voltage testing device for the GIS devices of the transformer stations is characterized in that the impulse voltage generating device is composed of a direct-current power source, resistors, capacitors, an inductor and fixed triggering gap switches in a connected mode, wherein the direct-current power source is connected with the capacitors in three-level parallel connection, and the fixed triggering gap switches through the resistors, and then is connected with a capacitive tested object in series through the inductor to form a tank circuit, and the impulse voltage generating device and the power source accessories are arranged on the same carrying platform. Due to the facts that the fixed triggering gap switches are adopted by the impulse withstand voltage testing device for the GIS devices of the transformer stations, and a transmission mechanism does not exist, debugging is not needed, and the defect of abnormal discharging of a discharge sphere gap can be effectively overcome.

Description

The GIS of transformer station kind equipment impulse voltage withstand test device
Technical field
The present invention relates to a kind of power equipment test unit, particularly a kind of GIS of transformer station kind equipment impulse voltage withstand test device.
Background technology
At present, the test unit that uses in the on-the-spot impulse voltage withstand test of the GIS of transformer station kind equipment mainly contains following defective and deficiency: the one, and the impulse voltage withstand test device that uses is generally the impulse voltage generator of indoor type, need on-site hoisting assembling, debugging, dismounting after test is finished, its testing ground work expends a large amount of manpower and materials, inefficiency is not easy to promote the use of on a large scale; The 2nd, the efficient of common impulse voltage generator is low, general efficient is 70%~80%, and the volume of equipment is large, heavy, be not easy to carrying, be not suitable for the demand of site test, the ball discharge gap in the generator is subject to weather influence, and easily be subject to external force in the process of transportation and be out of shape the abnormal discharge; The 3rd, on-the-spot service precision is lower, and wiring is loaded down with trivial details.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of rational in infrastructure, the on-the-spot reliably GIS of the transformer station kind equipment impulse voltage withstand test device that uses fast.
The object of the present invention is achieved like this: a kind of GIS of transformer station kind equipment impulse voltage withstand test device, formed by surge voltage generating means, power source accessory and Sheng carrying platform, it is characterized in that but described surge voltage generating means is connected and composed by direct supply, resistance, electric capacity, inductance, fixed triggered gap switch, but direct supply is connected with fixed triggered gap switch with the electric capacity of three grades of parallel connections by resistance, and connecting with the capacitive test specimen by inductance forms oscillation circuit again.
Described surge voltage generating means and power source accessory all are arranged on the same Sheng carrying platform.
The insulation that the present invention is directed to combined electric appliance equipment is the characteristics of capacitive character test product load, can form the LC oscillation circuit with test specimen electric capacity, thereby obtains the voltage of impulse voltage withstand test; But adopt fixed triggered gap switch, transmission mechanism-free need not be debugged, and can effectively overcome the defective of ball discharge gap paradoxical discharge, has also realized the miniaturization of device.The layout compact and reasonable of same Sheng carrying platform, easy and simple to handle, the problems such as assembling, debugging and dismantlement work amount are large, and wiring is loaded down with trivial details are hung at the scene of having solved, and have saved the human and material resources of testing ground, shorten the activity duration, increase work efficiency.
Description of drawings
Fig. 1 is the circuit theory diagrams of surge voltage generating means of the present invention;
Fig. 2 is the structural representation that the present invention is arranged at same Sheng carrying platform.
Embodiment
The invention will be further described below in conjunction with accompanying drawing:
As shown in Figure 1, direct voltage source U is through resistance R LThree grades of capacitor C parallel with one another SBut be connected capacitor C with three grades of fixed trigger ball gap switch f SBut pass through respectively the wave rear resistance R with fixed trigger ball gap switch f PAnd resistance R 0Connect with inductance L and capacitive test specimen C, thereby form oscillation circuit.
In order to produce high amplitude pulse voltage.Three grades of capacitor C in this loop SPass through in parallel resistance R LBe charged to voltage U o by direct voltage source U, then but the synchronous discharge through three grades of fixed trigger ball gap switch f is series connected, thereby obtain the pulse voltage of 3Uo nearly at test product, simultaneously, capacitor C through inductance L and test specimen forms oscillation circuit, thereby produce the lightning impulse voltage ripple of vibration, realize test objective.
As shown in Figure 2, in the present embodiment, as containing carrying platform, surge voltage generating means 2 and direct supply annex, TT﹠C system 3 etc. are assemblied in the container with container 1, and integral hoisting need not assembling at the scene.
