Description
Technical field
It the utility model is related to high-speed switch type series compensation device field, and in particular to a kind of high-speed switch type series connection is mended
Repay device metal oxide pressure-limiting device component.
Background technology
Metal oxide pressure-limiting device component (MOV) effect of series compensation device in transmission line of electricity primarily to occur
During earth fault, the overvoltage of limiting capacitance device group, the electric current due to flowing through MOV is line fault electric current, the duration is long,
MOV power consumption is very big, separately because the rated voltage of series capacitor compensation group will not be too high, so MOV rated voltage also will not be too
Height, based on above feature, this MOV must use multicolumn parallel form, and MOV line is flowed through in this multicolumn parallel-connection structure requirement
Road fault current is evenly distributed in each unit as far as possible, and this allows for the line fault electric current for flowing through metal oxide valve block
In hundreds of peace left and right.It follows that string mend with MOV have power consumption it is big, using multiple-unit it is in parallel, flow through MOV electric current in hundreds of peaces
The features such as left and right.For the MOV structures of series compensation when parallel units increase, its appearance and size becomes big, but because of series compensation device
Inner structure size limits, and MOV structure also needs to change.、
The content of the invention
In order to solve above-mentioned problems of the prior art, the utility model provides a kind of high-speed switch type series compensation
Device box metal oxide pressure-limiting device component (MOV) double-decker.
Technical scheme is used by the utility model：
A kind of high-speed switch type series compensation device metal oxide pressure-limiting device component, including the first pole plate, the second pole
Plate and multiple metal oxide pressure-limiting devices between the first pole plate and the second pole plate, in addition to tri-electrode, it is described
Tri-electrode is located at the top of the second pole plate, and parallel with the first pole plate, the second pole plate, and tri-electrode passes through a conducting rod
It is connected with the first pole plate；Multiple metal oxide pressure-limiting devices are distributed between second pole plate and the first pole plate.
Further, a circular hole is provided with second pole plate, the conducting rod passes through the second pole plate, institute by circular hole
State a diameter of 90-105mm of circular hole.
Further, the conducting rod is connected by bolt, plain cushion, spring washer respectively with the first pole plate, tri-electrode.
Further, the bottom surface of first pole plate is provided with multiple insulators.
Compared with prior art, the utility model has following technique effect：
The utility model is used to compensate the electric capacity in high-speed switch type series compensation device, if the type series connection of access high-speed switch
When voltage, the electric current of compensation device are excessive, it usually needs more metal oxide pressure-limiting device components come compensating electric capacity, this practicality
The new situation constant in high-speed switch type series compensation device box sizes can install multiunit MOV, and the cost of casing is not
Increase, effectively save financial cost；It is easy to the in-site installation of high-speed switch type series compensation device；It is easy to later stage high-speed switch type
The structure arrangement of series compensation device cabinet.
