Abstract
The utility model relates to an overvoltage protector widely used in a set of parallel compensation devices in an electric force transmission and transformation system. The utility model has the first structure that a lightning arrester is arranged on an insulating platform which can be realized by an insulating supporting post; the tail end of the lighting arrester is fixedly connected to the top end of the insulating supporting post, and the bottom end of the insulating supporting post is fixedly connected to an earthing frame. The utility model has another structure that the lightning arrester is fixedly connected to the earthing frame through a clamping hoop, and an umbrella edge structure is added on the tail of the lightning arrester between the outlet terminal of the lightning arrester and the clamping hoop. The utility model has the third structure that the lightning arrester is hung on a high voltage main wire, and the output end of the lightning arrester keeps a distance with the earthing frame. The three structures of the utility model all increase the insulation and the level of the outlet terminal of the lighting arrester to the ground, and thus, the lighting arrester can not discharge electricity to the ground, instruments are always in an optimum working state for monitoring the generation of overvoltage of an electric power system, problems in the prior art are solve smoothly, accident hidden troubles are eliminated, and the running safety of an electric power system is ensured.
Description
Technical field
The utility model relates to the overvoltage protection in the shunt compensation the complete sets of equipment that are widely used in the electric power power transmission and transformation system, the particularly improvement of its structure.
Background technology
Be widely used in the shunt compensation the complete sets of equipment in the electric power power transmission and transformation system, its structure comprises by outlet and the splicing ear between the instrument inlet wire, electric disturbance device and the capacitor of vacuum (few oil) switch, isolating switch, lightning arrester, measuring instrument, lightning arrester and forming.Because the frequent movement of vacuum switch constantly produces overvoltage, the damage capacitor, the existing lightning arrester that generally adopts suppresses the various overvoltage that occur in the electric power system, and the capacitor for voltage protection group exempts from superpotential damage.The overvoltage protection of this shunt compensation the complete sets of equipment is made up of lightning arrester, measuring instrument and splicing ear.The overvoltage protection of this structure, under the overvoltage effect, powerful impulse current goes into ground through instrument after flowing through lightning arrester again.Owing to have internal resistance in the instrument, when electric current through out-of-date, can produce the high pressure of approximately going up kilovolt between splicing ear and the ground energy drives instrumentation is provided, impel the splicing ear above earth potential to raise again simultaneously.Because the insulation level between splicing ear and the ground is very low, the input voltage of instrument is not elevated in the time of can driving the requiring of instrumentation as yet, and splicing ear has just discharged over the ground, thereby makes instrument to work, and does not play supervisory function bit.This situation.Especially serious in the rainy day, lightning arrester often occurs and damage, and measuring instrument is still reactionless, cause and in time to find and change lightning arrester and cause capacitor blast on fire, the serious accident that electrical network disintegrates leads to heavy economic loss, the safety of serious threat electric power system.
Summary of the invention
The utility model has overcome the shortcoming of said structure, and a kind of shunt compensation complete set of equipments overvoltage protection that has improved is provided.
The shunt compensation complete set of equipments can be built an insulated platform with first kind of structure of overvoltage protection, and lightning arrester is installed on the insulated platform.Insulated platform can be realized by an insulation column.Its structure includes measuring instrument 1, lightning arrester 2, insulation column 3, and the lightning arrester tail end is fixedly connected on the insulation column top, and the bottom of insulation column is fixedly connected on the ground connection framework 4.
The shunt compensation complete set of equipments includes measuring instrument 1, lightning arrester 2 with the another kind of structure of overvoltage protection, and lightning arrester is fixedly connected on the ground connection framework 4 by clip 7, and the lightning arrester afterbody between lightning arrester leading-out terminal 5 and the clip 7 increases umbrella rib structure 10.
The utility model shunt compensation complete set of equipments includes measuring instrument 1, lightning arrester 2 with the third structure of overvoltage protection, and lightning arrester is suspended on the high voltage bus 11, keeps at a distance between its output 5 and the ground connection framework 4; The inlet wire section of measuring instrument 1 connects lightning arrester leading-out terminal 5, and the leading-out terminal of measuring instrument connects ground.
Three kinds of structures of the utility model have all improved the leading-out terminal insulation against ground level of lightning arrester, and it can not discharged over the ground.Make instrument be in optimum Working forever,, successfully solved the problem that prior art exists, eliminated accident potential, the security of operation of electric power system is guaranteed to implement that superpotential monitoring is taken place in electric power system.
