Abstract
The utility model relates to an inner leakage handling device for a switch of a transformer, and belongs to the technical field of mounting of transformer equipment. According to the technical scheme, the device comprises a gas relay (1), a butterfly valve A (2), a butterfly valve B (3), an oil leveler pipe (4), a lower-section transformer oil tank (5), a load switch (6) and an oil conservator (9), wherein an oil tank of the transformer is communicated with the oil conservator (9) through a pipeline on which the gas relay (1) is arranged; the butterfly valve A (2) and the butterfly valve B (3) are arranged on the two sides of the gas relay (1); the oil leveler pipe (4) has a U-shaped structure; one end of the oil leveler pipe (4) is communicated with the lower-section transformer oil tank (5); the load switch (6) is also arranged on the transformer. The device has the beneficial effects that procedures for hanging the inner leakage of the switch of the transformer are simple; the device is low in cost and high in labor efficiency, and the safe running of the transformer is ensured.
Description
Technical field
The utility model relates to drain process device in a kind of transformer switch, belongs to transformer equipment mounting technique field.
Background technology
When transformer is installed at the scene, when finding that there is while leaking in load switch, as by normal handling procedure, need to prepare the equipment such as oil filter, oil tank, crane, then to transformer drain the oil, vacuum treatment, after processing, carry out the work such as acceptance test, handling procedure is loaded down with trivial details, and disposal cost is high, and various expenses add up to approximately 300,000 yuan, and at least need 5 day time, and in processing procedure, some links go wrong and all can impact transformer safe operation.
Utility model content
The utility model object is to provide drain process device in a kind of transformer switch, at transformer pouring fuel outlet valve, U-shaped oil ga(u)ge pipe is installed, and observes oil level state, utilizes negative pressure to process in switch and leaks, and solves the problem existing in background technology.
The technical solution of the utility model is:
Drain process device in a kind of transformer switch, air inclusion relay, butterfly valve A, butterfly valve B, oil ga(u)ge pipe, transformer lower oil tank, loaded switch and oil conservator, oil tank of transformer is communicated with oil conservator by pipeline, pipeline is provided with Buchholz relay, Buchholz relay both sides are provided with butterfly valve A and butterfly valve B, oil ga(u)ge pipe is U-shaped structure, and one end is communicated with transformer lower oil tank, is also provided with loaded switch on transformer.
Described oil ga(u)ge pipe is communicated with transformer lower oil tank by transformer pouring fuel outlet valve.
Described oil ga(u)ge pipe is fixed on transformer oil tank wall.
Adopt the utility model, when finding that there is while leaking in load switch, close Buchholz relay both sides butterfly valve A and butterfly valve B, make the micro-negative pressure of generation in transformer, observe oil level state by U-shaped oil ga(u)ge pipe, guarantee that transformer oil can be not excessive, guarantee the processing of leaking in loaded switch.
The beneficial effects of the utility model are: in transformer switch, drain process program is simple, and expense is low, and efficiency is high, has guaranteed the safe operation of transformer.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
In figure: Buchholz relay 1, butterfly valve A2, butterfly valve B3, oil ga(u)ge pipe 4, transformer lower oil tank 5, loaded switch 6, rising seat 7, bushing 8, oil conservator 9.
Embodiment
Below in conjunction with accompanying drawing, by example, the utility model is described in further detail.
With reference to accompanying drawing 1, drain process device in a kind of transformer switch, air inclusion relay 1, butterfly valve A2, butterfly valve B3, oil ga(u)ge pipe 4, transformer lower oil tank 5, loaded switch 6 and oil conservator 9, oil tank of transformer is communicated with oil conservator 9 by pipeline, pipeline is provided with Buchholz relay 1, Buchholz relay 1 both sides are provided with butterfly valve A2 and butterfly valve B3, oil ga(u)ge pipe 4 is U-shaped structure, one end is communicated with transformer lower oil tank 5 by transformer pouring fuel outlet valve, and be fixed on transformer oil tank wall, on transformer, be also provided with loaded switch 6.
When finding that there is while leaking in load switch, close Buchholz relay both sides butterfly valve A and butterfly valve B, process weather at tens hours nights is lowered the temperature naturally, make transformer top-oil temperature reduce 7-10 ℃, make to produce micro-negative pressure in transformer, observe oil level state by U-shaped oil ga(u)ge pipe, in the situation that the micro-negative pressure of transformer still keeps, guarantee that transformer oil can be not excessive, process in loaded switch and leak.
Utilize negative pressure not only can process leakage problem in switch, can also process fuel tank and push up other group parts problem, as pressure relief valve, low-tension bushing, wear the processing of the problems such as cable formula bushing.
