Description
Technical field
The invention belongs to electrical measuring device technical fields, and in particular to a kind of lightning arrester live-line test multi-function rotating tipping
It sets.
Background technique
Arrester is restriction effect in the important equipment of overvoltage on power grid, according to " the power transmission and transforming equipment shape of national grid
State tests testing regulations ", " 18 great anti-accident measures of State Grid Corporation of China " and five requirements such as logical, lightning arrester live-line test
It is tested before and after annual thunderstorm season, 1 year twice.Lightning arrester live-line test data can provide effectively for equipment state assessment
Support, and data variation rule over the years can provide foundation for prediction equipment operation condition, the precise and high efficiency of the data is obtained to institute
In safe and stable operation of power system important in inhibiting.
Several substations are administered by one test teams and groups, and situation difference of respectively standing, and have conventional open style substation and GIS power transformation
It stands.The lightning arrester with electrical testing meter that scene uses at present is to design for open type arrester, when testing, is kept away with subject
There are two contact points for thunder device, i.e., are clamped with the clip that two diameters are about 9cm to lightning stroke counter top and bottom and be grounded respectively
At band iron.
Currently, field application is the live testing instrument suitable for traditional open arrester, it is generally existing following
Technical disadvantages: GIS combines the electrical equipments such as bus, breaker, current transformer, voltage transformer, arrester, disconnecting switch
Together, have many advantages, such as that small occupied area, high reliablity, high safety, maintenance workload are small, traditional substation equipment is gradually
Updating is GIS type, and newly-built station is also mostly the station GIS.GIS arrester is very different with open type arrester appearance,
Have protective housing closing with testing instrument for electrified contact site, only in protective housing lower end there are osculum, inside without illumination component, to seeing
It examines contact situation and brings difficulty, therefore have particular/special requirement to test splice.
The connector for the design of open type arrester that scene uses at present, it is difficult to protrude into protective housing and reserve in bore, often
Appearance is not suitable for GIS arrester, clamping, and to being tested, position is difficult, is easy situations such as loosening, in some instances it may even be possible to occur testing electric current
Unstable damage instrument.Working efficiency is greatly reduced in the process for adjusting instrument connector repeatedly, and easily causes GIS arrester meter
The damage of a number lead-out wire insulated porcelain sleeve of device, even brings security risk when contacting unstable.
If opening protective housing to be tested, because of long-play, there is corrosion situation in chamber door with part GIS arrester, open
Difficulty, when test, tear lid open and restore that time-consuming, corrode serious or even can not restore to original state.Aperture is tested in protective housing
Underface, pore size is different, and the presence of these objective factors is brought a lot of trouble to test job.In order to effectively change this
It is imperative to develop GIS tank-type lightning arrester live testing multifunctional switching device for status.
The patent document of Publication No. CN206002568U discloses a kind of lightning arrester live-line test connecting rod, including conduction
Connector, Universal pipe, insulating bar and test connecting line, the conductive connection head with the tail end of arrester for contacting, and described ten thousand
It is connect to the first end of pipe with the conductive connection head, the second end of the Universal pipe is connect with one end of the insulating bar, institute
The one end for stating test connecting line is connect with the conductive connection head, and the other end of the test connecting line is used to connect with test equipment
It connects.The lightning arrester live-line test connecting rod, testing crew can hold insulating bar and be tested, and can facilitate completion on the ground
Corresponding wiring is not needed using ladder, can be reduced workload, be improved working efficiency, reduce operating risk.In addition, by leading
Universal pipe is set between electrical connector and insulating bar, facilitates the company of control conductive connection head and arrester tail end convenient for testing crew
It connects, and angular adjustment is convenient, can further improve working efficiency.The utility model is conductively connected header structure cannot be according to arrester
The size at tested position is changed.
The patent document of Publication No. CN208207012U provides a kind of Special-purpose test tool for electrified lightning arrester, including stretches
Contracting insulating bar, be arranged in telescopic insulating bar one end conductive structure test clip and the behaviour of the telescopic insulating bar other end is set
Make handle；The test clip and the telescopic insulating bar are rotatablely connected；It is provided on the operating handle for controlling the survey
Examination folder opens and the connection structure of closure；Described connection structure one end is connected with operating handle, the connection structure other end
It is connected with test clip；The p-wire of connecting test instrument is additionally provided on the test clip.The utility model test clip is clip shape
Structure is not suitable for the live testing of GIS arrester suitable for the live testing of traditional open arrester.
