Abstract
The utility model belongs to electric power application, particularly relates to high-power transformer partial discharge test radome.A kind of high-power transformer partial discharge test radome, comprise radome, clip and bushing shell for transformer, bushing shell for transformer top arranges U-shaped radome, and in radome, top pad bare copper wire connects clip; Sidewall arranges hand hole.It is arranged on it on the sleeve pipe of transformer A, B, C three-phase by testing crew respectively when applying.Because spot jamming resource is many, adopt this device make conduit connection place Electric Field Distribution evenly, prevent the discharge capacity produced owing to puncturing air to be mixed in measured value, play the effect of electric fields uniform distribution.
Description
Technical field
The utility model belongs to electric power application, particularly relates to high-power transformer partial discharge test radome.
Background technology
In recent years, electric system is configured with much large-scale transformer station.Transformer is as ingredient important in electric system, and its operation conditions how, the security of operation of the whole electric system of direct relation, once have an accident, can cause heavy economic losses, brings interruption also can to social electricity consumption.Partial discharge test is the main experimental project of transformer performance, and it mainly checks inside transformer, due to the non-through electric discharge phenomena that weak place of insulating occurs.It can not make the insulativity of electrical equipment be punctured immediately, but because of its produce physics and chemical reaction, insulation defect can be made constantly to expand, and then cause insulation breakdown.According to GB 50150-2006 " Erection works of electrical installations Standard for handover test of electric equipment " 220 kV and above transformer do at the scene commissioning test and all, part more emat coil time, must partial discharge test be done.At present, most high-power transformer partial discharge test lacks radome, and what have individually exists unreasonable structure, and shield effectiveness is poor, is difficult to the demand meeting high-power transformer partial discharge test, urgently improves.
Utility model content
The utility model is for problems of the prior art, provide a kind of high-power transformer partial discharge test radome, fundamental purpose be make conduit connection place Electric Field Distribution evenly, prevent due to puncture air produce discharge capacity be mixed in measured value, play electric fields uniform distribution effect.
The technical solution of the utility model is as follows: a kind of high-power transformer partial discharge test radome, and comprise radome, clip and bushing shell for transformer, bushing shell for transformer top arranges U-shaped radome, and in radome, top pad bare copper wire connects clip; Sidewall arranges hand hole.
Technical characterstic of the present utility model is as follows: easy to use and flexible; Transformer is all very high also will be installed on bushing shell for transformer radome, and be convenient to carrying owing to have employed aluminum very light in weight, the design experiment personnel that have employed two hand holes are easy to install and wiring; Test effect is good, because radome have employed copper short-circuit line and clip, sleeve pipe is connected tightr with radome; Preventing transformer high-voltage to puncture air produces dangerous, is exactly arc light; Completely cut off electromagnetic wave simultaneously, ensure that safety; Prevent and discharged and prevent arc discharge in the place of mistake, strengthen Secure isolation; Main object makes the Electric Field Distribution at conduit connection place more even, prevents the discharge capacity produced owing to puncturing air to be mixed in measured value, play uniform electric field distribution effect.
Accompanying drawing explanation
Fig. 1 is partial discharge of transformer private mask cover structure schematic diagram; Fig. 2 is partial discharge of transformer private mask cover practical application figure.Wherein radome 1, clip 2, bare copper wire 3, pad 4, hand hole 5, bushing shell for transformer 6.
Embodiment
Embodiment: the utility model mainly develops high-power transformer partial discharge test radome, the high 60cm of radome 1, lower port diameter 30cm that full aluminum makes, two hand hole 5 diameter 10cm; Top 12mm in radome 1
2bare copper wire 3 pad 4, the other end connection clamp 2 of bare copper wire 3.It is arranged on it on the sleeve pipe of transformer A, B, C three-phase by testing crew respectively when applying.Because spot jamming resource is many, adopt this device make conduit connection place Electric Field Distribution evenly, prevent the discharge capacity produced owing to puncturing air to be mixed in measured value, play the effect of electric fields uniform distribution.
This technology is applied to the Lanzhou-Xinjiang transformer station 220kV of state net new clothes 220kV mono-, No. two Existing during Partial Discharge Test for Transformers; The friendly transformer station 220kV of 220kV mono-, No. two Existing during Partial Discharge Test for Transformers; 220kV Zhong Zhai transformer station 220kV No. bis-transformer overhaul partial discharge tests; 220kV peace transformer station 220kV No. five transformer overhaul partial discharge tests, all achieve good results, improve test mass.
