Technical field
The utility model relates to a kind of power equipment test unit, particularly a kind of on-the-spot with wave of oscillation lightning impulse generating means.
Background technology
In the on-the-spot impulse voltage withstand test of transformer station's gas insulated switching installation of electric power system, the test unit used mainly contains following defect and deficiency: 1, the impulse voltage withstand test device is generally the impulse voltage generator of indoor type, need on-site hoisting assembling, debugging, tested rear dismounting, its testing ground work expends a large amount of manpower and materials, inefficiency, be not easy to promote the use of on a large scale; 2, the efficiency of common impulse voltage generator is low, general efficiency 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 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 electric discharge; 3, on-the-spot service precision is lower, and wiring is loaded down with trivial details.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of rational in infrastructure, the on-the-spot wave of oscillation lightning impulse generating means for scene reliably that uses fast.
The purpose of this utility model is achieved in that a kind of on-the-spot with wave of oscillation lightning impulse generating means, by surge voltage generating means, power source accessory and Sheng carrying platform, formed, 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, then the formation oscillation circuit of connecting with the capacitive test specimen by inductance.
Described surge voltage generating means and power source accessory all are arranged on same Sheng carrying platform.
The utility model is the characteristics of capacitive character test product load for the insulation of combined electric appliance equipment, 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 debug, and can effectively overcome the defect of ball discharge gap paradoxical discharge, 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.
The accompanying drawing explanation
Fig. 1 is the circuit theory diagrams of the utility model surge voltage generating means;
Fig. 2 is the structural representation that the utility model is arranged at same Sheng carrying platform.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, direct voltage source U is through resistance R
lthree grades of capacitor C parallel with one another
sbut with three grades of fixed trigger ball gap switch f, be connected, capacitor C
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 on 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, using container 1 as containing carrying platform, surge voltage generating means 2 and direct supply annex, TT&C system 3 etc. are assemblied in a container, and integral hoisting, at the scene without assembling.
