Abstract
The utility model discloses a transformation reactor used for a frequency modulation series resonance high-voltage test, which comprises a secondary coil 1, an epoxy resin encapsulating layer 2, a primary coil 3, a framework tube 4 and an iron core 5, and is characterized in that an exciting transformer and a resonance reactor are combined, i.e. a coil (equivalent to the transformer primary) is added on the basis of the original structure of the resonance reactor, and the added coil and the original coil (equivalent to the transformer secondary) form a coupling relationship so as to obtain double functions of transformation and reactance, and the reactor, a variable frequency power source and a measuring voltage divider can constitute a frequency modulation series resonance high-voltage test device. The number of components of the frequency modulation series resonance high-voltage test device with the transformation reactor is reduced by one, system wiring and device transportation are convenient, and the reliability is improved. In addition, because the coupling between the primary and the secondary of the transformation reactor is weaker, the feedback or counterattack energy of a launch control (LC) circuit can not be easily transmitted to one side of the variable frequency power source, and the variable frequency power source and the operator are naturally protected.
Description
Technical field
The utility model relates to the electrical test complete equipment, especially frequency modulation series resonance high-pressure test device.
Background technology
Before circuit on power system puts into operation or after the maintenance, all to test the local discharge test that gets up comprising basic and important withstand voltage test and newly-developed to the state of insulation of force device or equipment.No matter withstand voltage test or local discharge test all will apply high voltage to test specimen.The method that applies ac high-voltage probably has three kinds: excute a law outward, inductive method and resonance method.Resonance method is to utilize reactor and test specimen (being equivalent to capacitor) to form the LC loop, makes the loop reach resonant condition by transferring modes such as sense or frequency modulation, thereby produce high voltage on test specimen.Frequency modulation series resonance high-pressure test device promptly is to utilize mode of frequency regulation to realize the resonance method high-potting, and reactor wherein adopts fixed reactor.
Frequency modulation series resonance high-pressure test device in the past is made up of variable-frequency power sources, driver transformer, resonance reactor and measurement voltage divider, and kit is more, system's line trouble.
Summary of the invention
The purpose of this utility model is to provide a kind of frequency modulation series resonance high-potting transformer/reactor, makes it to form frequency modulation series resonance high-pressure test device with variable-frequency power sources and measurement voltage divider, finishes the pressurization task of various electrical tests.For achieving this end, the utility model unites two into one driver transformer and resonance reactor, on the configuration basis of original resonance reactor, increase a coil (being equivalent to primary), and form coupled relation with reactor winding (being equivalent to transformer secondary output), variable-frequency power sources is coupled to reactor winding to exciting power by this coil, produces high voltage thereby promote LC loop generation resonance on test specimen.This be transformer be again that the transformer/reactor of reactor makes frequency modulation series resonance high-potting complete equipment reduce by an assembly, operational reliability is improved, and both weight after merging are less than they single-piece weight sums, and this system wiring and equipment carrying to electrical test work brings great convenience.In addition; because a little less than primary and secondary the coupling of transformer/reactor; when test outage occurs or discharges when unusual; LC circuit feedback or counterattack energy are difficult for being delivered to variable-frequency power sources one side; naturally protected variable-frequency power sources and operator safety, this to ensure the high-voltage electrical apparatus test carry out smoothly significant.
