Abstract
The utility model discloses a voltage-regulation type automatic special voltage regulator for reactive power compensation, comprising an oil tank, an oil conservator installed at the upper part of the oil tank, as well as a transformer body and an on-load tap switch which are arranged in the oil tank, wherein the oil tank is composed of a tank bottom, a tank wall and a tank cover; the tank cover is provided with a cavity for holding one part of the on-load tap switch higher than the tank cover, the upper end of the cavity is of a sealed structure, while the lower end is communicated with the oil tank, and an insulating clearance is reserved between the inner wall and the on-load tap switch. The cavity is composed of a rising base fixedly connected on the tank cover as well as a top cover connected on the upper port of the rising base by threads; and the cavity is cylindrical or ellipsoidal-cylindrical. Compared with the prior art, the technical scheme not only solves the problem for holding the super-high on-load tap switch, but also lowers the whole height of the oil tank, greatly saves expensive special transformer oil and steel plate materials, and reduces production cost.
Description
Technical field
The utility model relates to the voltage regulator that power industry is used, especially the special-purpose voltage regulator of voltage regulation type auto-reactive compensation.
Background technology
The special-purpose voltage regulator of voltage regulation type auto-reactive compensation is the autotransformer structure.Because the autotransformer electromagnetic capacity is little, save material, thereby volume is less.When the special-purpose voltage regulator of described voltage regulation type auto-reactive compensation is selected on load tap changer for use, usually can have the situation of the setting height(from bottom) size of on-load shunting switch greater than fuel tank clear height size, therefore need increase the fuel tank overall height dimension.Increase the fuel tank overall height dimension because of the local height size surpasses fuel tank clear height size, increased the idle space in the fuel tank.We know, must be full of dedicated transformer oil in the fuel tank of oil-filled transformer, and the increase of idle space is not only wasted the tank wall steel plate of fuel tank, and wasted the valuable dedicated transformer oil that is filled in this idle space, has increased production cost greatly.
The utility model content
The purpose of this utility model is: a kind of compact conformation is provided, saves and produce the special-purpose voltage regulator of raw-material voltage regulation type auto-reactive compensation.
For achieving the above object, the utility model can be taked following technical proposals:
The special-purpose voltage regulator of the utility model voltage regulation type auto-reactive compensation, comprise fuel tank, be arranged on the conservator on described fuel tank top, be installed in transformer body and on load tap changer in the described fuel tank, described fuel tank by case at the bottom of, tank wall and case lid constitute, be provided with the chamber that ccontaining described on load tap changer exceeds the case lid part on described case lid, the upper end of this chamber is to leave clearance for insulation between hermetically-sealed construction, lower end and fuel tank perforation, inwall and the described on load tap changer.
Described chamber constitutes the cylindrical or elliptical cylinder-shape of this chamber by the rising seat that is fixed on the described case lid with the top cover that is screwed onto this rising seat upper port.
The seat wall steel plate thickness of the described seat that raises is the 4-6 millimeter, and the height of the seat that raises is the 80-250 millimeter.
The technical solution of the utility model, owing to adopt and the rising cavity be set at fuel tank top and part, on load tap changer corresponding position, compared with prior art, both solved the problem of the on load tap changer of ccontaining superelevation, reduced the whole height of fuel tank again, save steel plate materials and expensive dedicated transformer oil greatly, reduced production cost.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is that the A of Fig. 1 is to local schematic top plan view.
Embodiment
As illustrated in figs. 1 and 2, the special-purpose voltage regulator of the utility model voltage regulation type auto-reactive compensation, comprise by at the bottom of the case 4, the fuel tank that constitutes of tank wall 5 and case lid 6, be arranged on the conservator 1 on described fuel tank top, be installed in transformer body 2 and on load tap changer 3 in the described fuel tank, on described case lid 6, be provided with the chamber that ccontaining described on load tap changer 3 exceeds case lid 6 parts.Described chamber is cylindrical, constitutes by being welded on the rising seat 7 on the described case lid 6 and sealing the top cover 8 that is screwed onto these rising seat 7 upper port, and its lower end and fuel tank connect, and leave clearance for insulation between its inwall and the described on load tap changer 3.Skull 9 sealings of described on load tap changer 3 are screwed onto on the described top cover 8.The seat wall of the described seat 7 that raises is selected the steel plate of 4 millimeters thick for use, and the height of the seat 7 that raises is 200 millimeters, normally moves with the skull 9 lower gear transmission mechanisms that guarantee on load tap changer 3.
