Abstract
The utility model discloses a totally-enclosed oil-immersed high-voltage metering box. The high-voltage metering box comprises a box body, as well as an upper cover and porcelain bushings, which are arranged on the box body, wherein the upper cover and the box body adopt an integral structure and together form a cavity; the bottom ends of the porcelain bushings are arranged in the cavity; two epoxy resin wiring seats are respectively sleeved at the top ends of the porcelain bushings; wiring copper bars are arranged on the epoxy resin wiring seats; and each epoxy resin wiring seat comprises a wiring seat body, a joint is arranged on the wiring seat body, and the wiring copper bar is mounted on the joint. In the utility model, the new epoxy resin wiring seats are mounted at the terminal ends of the porcelain bushings, so the sealing performance of the terminals are greatly improved; the wiring copper bars are arranged on the wiring seats to replace the conventional line-to-line manner with a line-to-surface manner, so that the electric conductivity is increased, meanwhile, the electric-field balancing performance is improved; and the totally-enclosed oil-immersed high-voltage metering box has a favorable application prospect.
Description
Technical field
The utility model relates to technical field of power systems, particularly relates to a kind of totally-enclosed oil-immersed and high-voltage batch meter.
Background technology
High-voltage measuring box is a kind of device that is mainly used in high voltage electric energy, voltage and electric current metering, along with the development of electric power system towards directions such as high voltage, big capacity, guarantees that the power system security operation reliably and the problem of accurate measurement just seem particularly important.
Divide according to insulation mode, High-voltage measuring box mainly can be divided into dry type, casting type, oil immersed type and gas-filled type at present, the oil-immersed and high-voltage batch meter is because its insulation property are better, be mainly used in the above outdoor type power distribution equipment of 10KV, as shown in Figure 6, be present traditional oil-immersed and high-voltage batch meter, mainly there is the weak point of the following aspects in present oil-immersed and high-voltage batch meter: the terminals on (1) insulator adopt the design of line line contact, electric conductivity is good inadequately, and the ability of balanced electric field is strong inadequately; (2) adopt securing members such as screw, bolt fastening between casing and the loam cake, sealing property is relatively poor; (3) transformer oil is often filled casing, does not have the design pressure buffering area, and external environment condition can exert an influence to the oil plant district of inside, causes pressure beyond thought variation to occur; (4) casing is generally the iron case, and it is damp proof, moistureproof, corrosion resistant indifferent, just can go wrong after use a period of time.
Because the above defective is necessary the design of oil-immersed and high-voltage batch meter is proposed new requirement.
The utility model content
At the problems referred to above, the utility model provides a kind of totally-enclosed oil-immersed and high-voltage batch meter.
The utility model is that the technical scheme that its technical problem of solution is adopted is:
A kind of totally-enclosed oil-immersed and high-voltage batch meter, comprise casing, be located at loam cake and insulator on the casing, it is characterized in that: the integrated molding structure of described loam cake and casing, both common formation one cavitys, described insulator bottom is located in this cavity, be with an epoxy resin junction block on its top, described epoxy resin junction block is provided with copper busbar.
As further improvement of these options, described epoxy resin junction block comprises the junction block body, and described junction block body is provided with joint, and described copper busbar is installed on the joint.
Further, in the described casing transformer oil is housed, the common positive/negative pressure buffering area that forms of described transformer oil and casing and loam cake.
Further, cover on described and be provided with pressure relief valve, pressure relief valve is connected with described positive/negative pressure buffering area.
In addition, described casing is a stainless steel.
The beneficial effects of the utility model are: (1) the utility model has been installed the neo-epoxy resin junction block at the terminal stud of insulator, make the sealing property of terminals improve greatly, junction block is provided with copper busbar, replace traditional line line formula with line face formula, increase its electric conductivity, improved the performance of balanced electric field simultaneously; (2) transformer oil and casing and loam cake form a positive/negative pressure buffering area jointly, can effectively mate the variation of external environment, will drop to minimum to the influence in the casing; (3) casing and loam cake adopt incorporate design, make the sealing property of High-voltage measuring box integral body improve; (4) casing adopts stainless steel, and is withstand voltage corrosion-resistant; That the utility model has reached is totally-enclosed, conduct electricity very well, corrosion-resistant resistant to pollution premium quality product, possesses good prospects for application.
