Description
Technical field
The present invention relates to a kind of power equipment, particularly a kind of adjustable power capacitor electric discharge device.
Background technology
For the application of low-pressure reactive compensation, because the reactive power of load in most cases changes than very fast, this just requires the input of power capacitor and the frequency ratio very fast (in 5 seconds) of excision.In view of the situation down; Will produce a problem: under its electric weight of capacitor of firm excision does not discharge completely situation fully; Just drop into once more again; The voltage of capacitor can produce certain voltge surge to fling-cut switch even electrical network like this, thereby causes the damage of fling-cut switch and the increase of mains by harmonics easily.
For addressing this problem, the discharge device of a capacitor through being connected in parallel with capacitor carries out repid discharge to capacitor firm immediately behind the excision capacitor, thus the problem of solution voltge surge.
At present, the discharge device of a capacitor that solves above-mentioned voltge surge problem designs according to fixing parameter when production is dispatched from the factory, and in use cannot in the light of actual conditions adjust, and uses inconvenience, increases power loss simultaneously.
Summary of the invention
In order to solve existing the problems referred to above, the object of the present invention is to provide a kind of easy to use, discharge parameter is adjustable, reduce the adjustable power capacitor electric discharge device of power loss.
The present invention for the technical scheme that solves its technical problem and adopt is:
Adjustable power capacitor electric discharge device comprises three discharge coils, and an end of each discharge coil is an external terminal, and an other end is in series with adjustable resistor respectively.
The inductance parameters of each discharge coil, coil D.C. resistance resistance parameter unanimity, the resistance parameter of each adjustable resistor is consistent.
Described adjustable resistor is the coordinated type adjustable resistor.
The invention has the beneficial effects as follows: adopt electric discharge device; Can promote the capacitor switching frequency, shorten and drop into blanking time, reach the purpose of dynamic compensation; The capacitor for voltage protection switching particularly adopts this silicon controlled switch of thyristor with switch (contactor, combination switch, thyristor etc.); Adopt the discharge mode of discharge lamp, discharge resistance relatively, the advantage that have rapidly and efficiently, caloric value is low; Simultaneously, because this power capacitor electric discharge device is employed in the structure of series connection adjustable resistor on the discharge coil, discharge parameter is adjustable; Guaranteeing under the immovable situation of discharge performance; Reduce power consumption,, can install this device additional existing operating reactive power compensator to reach considerable economical operation property; Reach the purpose that promotes performance, life-saving, and improvement cost is cheap, effect is obvious.
