Abstract
The invention discloses a kind of fixed structures of board-like current potential resistance, including being located at the current potential resistance below loaded switch, current potential resistance is fixed on fuel tank bottom, the two sides of current potential resistance are symmetrically arranged with high pressure lower clamping piece, low pressure lower clamping piece, it is characterized in that, it is respectively equipped with fixed plate on the high pressure lower clamping piece, low pressure lower clamping piece, electrical laminated wooden piece one is equipped in fixed plate, current potential resistance is fixedly connected with this two electrical laminated wooden piece one.The present invention can be realized the independently installed of board-like current potential resistance, reduce the height of loaded switch, and the height of oil tank of transformer also becomes smaller therewith, the dosage of steel plate and transformer oil be reduced, to substantially reduce the manufacturing cost of transformer.
Description
Technical field
The present invention relates to a kind of support constructions of the board-like current potential resistance of oil-immersed transformer loaded switch, belong to power equipment
Technical field.
Background technique
For on-load regulator transformer, is realized in the case where not cutting off load and adjust voltage function.In positive and negative tune
In pressure and thick, fine tuning pressure mode, because tap-changing windings are temporarily separated with winding during the operation of tap switch change over selector, tap
Winding electric potential floating.If floating potential will discharge greatly very much, decomposes transformer oil and generates gas, endanger product insulation performance,
It is just needed by the way of accessing current potential resistance to solve above-mentioned harm.Traditional current potential resistance is mounted in the bottom of loaded switch
Portion and height it is very big, virtually just increased the height of loaded switch, the height of oil tank of transformer forced also to increase therewith
Height, to increase the manufacturing cost of transformer.
Summary of the invention
Problem to be solved by this invention is existing current potential resistance height large increase transformer cost.
To solve the above-mentioned problems, technical solution of the present invention provides a kind of fixed structure of board-like current potential resistance, packet
The current potential resistance being located at below loaded switch is included, current potential resistance is fixed on fuel tank bottom, and the two sides of current potential resistance are symmetrically arranged with height
Depress folder, low pressure lower clamping piece, which is characterized in that it is respectively equipped with fixed plate on the high pressure lower clamping piece, low pressure lower clamping piece, it is fixed
Electrical laminated wooden piece one is equipped on plate, current potential resistance is fixedly connected with this two electrical laminated wooden piece one.
Preferably, it is connected between the electrical laminated wooden piece one and fuel tank bottom by electrical laminated wooden piece two.
Preferably, the current potential resistance is connected and fixed on high pressure lower clamping piece, low pressure lower clamping piece upside.
Preferably, the electrical laminated wooden piece one is L-type structure.
The beneficial effects of the present invention are: it can be realized the independently installed of board-like current potential resistance, reduce the height of loaded switch
Degree, the height of oil tank of transformer also become smaller therewith, the dosage of steel plate and transformer oil are reduced, to substantially reduce the system of transformer
Cause this.
Detailed description of the invention
Fig. 1 is the main view of the fixed structure of board-like current potential resistance provided by the invention;
Fig. 2 is the top view of Fig. 1.
Specific embodiment
In order to make the present invention more obvious and understandable, hereby with preferred embodiment, and attached drawing is cooperated to be described in detail below.
Embodiment
It is a kind of fixed structure of board-like current potential resistance provided by the invention as shown in claim 1, current potential resistance 2 is pacified
In fuel tank bottom 5, under the top installation loaded switch 1 of fuel tank inner potential resistance 2, the two sides of current potential resistance 2 are symmetrically arranged with
Lower clamping piece 7, respectively high pressure lower clamping piece, low pressure lower clamping piece, it is symmetrical with the center line of the two on high pressure lower clamping piece, low pressure lower clamping piece
Weld one piece of fixed plate 6;The electrical laminated wooden piece 1 an of L-type structure is symmetrically installed in fixed plate 6 again, with the bolt of nigrescence
Nut and gasket fastening;Current potential resistance 2 is placed in this two electrical laminated wooden piece 1, with insulation blanket stud and nut fastening (electricity
It is provided with and the matched mounting hole of current potential resistance 2 in work lamination wooden piece 1);It is used between electrical laminated wooden piece 1 and fuel tank bottom 5
Electrical laminated wooden piece 4 supports reality, in this way, current potential resistance 2 is secured firmly to the lower section of loaded switch 1 immediately.
