Abstract
The utility model discloses a kind of improved transformer Buchholz relay, it comprises Buchholz relay, the two ends of Buchholz relay are communicated with conservator with transformer body respectively by pipeline, are full of transformer oil in Buchholz relay, are provided with observation window in the both sides of Buchholz relay; Be provided with 2 ~ 3 the stainless steel hollow balls swum on transformer oil surface in Buchholz relay, Buchholz relay inner top surface is close at stainless steel hollow ball top; Observation window top is higher than the pipeline 2 ~ 3cm between Buchholz relay and transformer body; Two ends and the pipeline junction of Buchholz relay are provided with wire netting.The utility model structure is simple, and reasonable in design, easy to use, cost of manufacture is low, and operations staff observes the float position of stainless steel hollow ball by observation window, can accurately judge Buchholz relay inner case, determine fault.
Description
Technical field
The utility model relates to transformer accessory technical field, especially relates to a kind of improved transformer Buchholz relay.
Background technology
Buchholz relay is the important protection component of one of reflection transformer body fault, and it is contained in the oil pipe between the conservator of transformer and fuel tank.At present, staff makes an inspection tour transformer or transformer when quoting Gas Signal, need by the observation window of Buchholz relay, check relay inner with or without gas to judge fault.Along with updating of oil product processing technology, the quality of transformer insulation oil is become better and better, lighter, and the operations staff of lack of experience is difficult to judge that Buchholz relay inside is gas or insulating oil.
Summary of the invention
For solving the problem, the purpose of this utility model is to provide simple, the reasonable in design novelty of a kind of structure, improved transformer Buchholz relay that result of use is good.
For achieving the above object, the utility model adopts following technical scheme:
A kind of improved transformer Buchholz relay, it comprises Buchholz relay, and the two ends of Buchholz relay are communicated with conservator with transformer body respectively by pipeline, are full of transformer oil in Buchholz relay, is provided with observation window in the both sides of Buchholz relay; Be provided with 2 ~ 3 the stainless steel hollow balls swum on transformer oil surface in Buchholz relay, Buchholz relay inner top surface is close at stainless steel hollow ball top; Observation window top is higher than the pipeline 2 ~ 3cm between Buchholz relay and transformer body; Two ends and the pipeline junction of Buchholz relay are provided with wire netting.
Owing to adopting technical scheme as above, the utility model has following superiority:
This improved transformer Buchholz relay, its structure is simple, and reasonable in design, easy to use, cost of manufacture is low, and operations staff observes the float position of stainless steel hollow ball by observation window, can accurately judge Buchholz relay inner case, determine fault.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model improved transformer Buchholz relay;
Fig. 2 is the Buchholz relay internal structure schematic diagram in Fig. 1;
In figure: 1-transformer body; 2(a, b)-pipeline; 3-Buchholz relay; 4-over cap; 5-observation window; 6-conservator; 7-stainless steel hollow ball; 8-transformer oil.
Embodiment
Below in conjunction with drawings and Examples, the technical solution of the utility model is described in further detail.
As shown in Figure 1, 2, this improved transformer Buchholz relay, it comprises Buchholz relay 3, the two ends of Buchholz relay 3 are communicated with conservator 6 with transformer body 1 respectively by pipeline 2a, pipeline 2b, be full of transformer oil 8 in Buchholz relay, the observation window 5 of protected lid 4 protection is installed in the both sides of Buchholz relay; Be provided with 2 ~ 3 the stainless steel hollow balls 7 swum on 8, transformer oil in Buchholz relay 3, Buchholz relay inner top surface is close at stainless steel hollow ball top; Observation window 5 top, higher than the pipeline 2 ~ 3cm between Buchholz relay and transformer body, can be convenient to operations staff and observe; Two end flanges of Buchholz relay and pipeline 2a, pipeline 2b junction are provided with wire netting, can prevent stainless steel hollow ball from entering in above-mentioned pipeline.
Operations staff observes the float position of stainless steel hollow ball by observation window, when Buchholz relay inner top surface is close at stainless steel hollow ball top, illustrate in Buchholz relay without gas, when stainless steel hollow ball top departs from Buchholz relay inner top surface, illustrate in Buchholz relay have gas, operations staff can intuitive judgment fault.
