Abstract
The utility model provides an outdoor SF 6 circuit breaker divide -shut brake time measurement termination, include scalable insulator spindle (1), connect through screw thread (2) install magnet under the rectangle on insulator spindle top (3), be located down the magnet top and can with the rectangle of magnet actuation down on magnet (4), install crotch (5) in the middle of last magnet top surface, install in terminal (6) at last magnet one side edge. The utility model discloses do not need high altitude construction, safe and reliable, convenient operation.
Description
Technical field
This utility model is related to technical field of electrical measurement, particularly circuit-breaker switching on-off measure of time termination technology
Field.
Background technology
Chopper is divided into interior and outdoor two kinds, and outdoor sulfur hexafluoride breaker is that in transformer station, requisite electric power sets
Standby, the quantity of use is also very big, carries the zero load switching on and off high-tension circuit under normal circumstances and load current,
Can match with protection device and automaton during system jam, rapid disengagement failure electric current, Accident prevention expand it is ensured that
The important process such as electric power netting safe running.
Breaker closing time anomaly can cause three-phase current to differ greatly, and may cause protection overcurrent tripping；During separating brake
Between abnormal can lead to cut long voltage levels nonloaded line or Large Copacity no-load transformer causes switching overvoltage, be likely to result in and be
Unite apparatus insulated damage.Accordingly, it would be desirable to periodically chopper is carried out with branch wire time test.Due to 110kv and above outdoor six
Sulfur fluoride chopper is highly very high, and existing operation is required for realizing test using Insulation ladder or high-altitude operation vehicle connecing
Line, the high pendant of the personnel that increased and touch by mistake and close on powered risk, meanwhile, also have that operating platform truck is improper to cause electrical equipment to touch
The bad possibility of damage.
Content of the invention
The purpose of this utility model is to overcome the shortcomings of the existing mode of connection, provides one kind not need work high above the ground, safety
Reliability, easy to operate 110kv and above open air sulfur hexafluoride breaker branch wire time measurement termination.
The purpose of this utility model is achieved through the following technical solutions:
A kind of open air sulfur hexafluoride breaker branch wire time measurement termination, including telescopic insulation rod, passes through spiral shell
Stricture of vagina be connected and installed in insulating bar top rectangle lower magnet, be located at lower magnet above and can be with magnetic on the rectangle of lower magnet adhesive
Ferrum, the binding post being installed on the middle crotch of upper magnet top surface, being installed on upper magnet one lateral edges.
Described telescopic insulation rod is made up of the above insulated sleeve socket of two sections.
This utility model provide a kind of scalable, with crotch, magnetic-type insulating bar top detachable exempt to ascend a height connect
Line apparatus.Compared with existing termination, the beneficial effects of the utility model are: tester may stand in ground and passes through to stretch
Contracting bar completes test connection, without stair climbing or high-altitude operation vehicle, it is to avoid personnel's height falls and touches by mistake and closes on powered risk.Insulation
Masthead end is threaded connection rectangle lower magnet, lower magnet adhesive upper magnet again, facilitates insulating bar to separate with upper magnet p-wire,
Insulating bar is avoided to cause error to measurement.Testing crew quantity and setting up time can be reduced using this utility model, improve test
Efficiency.
Brief description
Fig. 1 is structural representation of the present utility model.
Specific embodiment
Outdoor sulfur hexafluoride breaker branch wire time as shown in Figure 1 measures termination, be mainly used in 110kv and with
The branch wire time measurement of upper open air sulfur hexafluoride breaker, is connected and installed in absolutely including telescopic insulation rod 1, by screw thread 2
The rectangle lower magnet 3 at edge masthead end, be located at lower magnet above and can with the rectangle upper magnet 4 of lower magnet adhesive, be installed on upper magnetic
Crotch 5 in the middle of ferrum top surface, it is installed on the binding post 6 of upper magnet one lateral edges.Telescopic insulation rod 1 is by the two above insulation sleeves of section
Pipe socket composition.
The method and step that this utility model uses at the scene is as follows:
The first step: will p-wire insertion binding post 6 fixed:
Second step: whether adhesive reliability is it is ensured that upper and lower Magnet reliably separates for detection upper magnet 4 and lower magnet 3；
3rd step: adjust the collapsing length of insulating bar according to the height of tested chopper cable；
4th step: whole termination is slowly raised, crotch 5 is reliably suspended on chopper cable, gently firmly
So that lower magnet is separated with upper magnet, p-wire is correctly connected with the binding post of circuit breaker characteristic tester simultaneously, you can start
Test job.
Telescopic insulation rod of the present utility model is made up of the insulating bar of more piece, regulation can be needed suitably high according to scene
Degree.Insulating bar top is threaded connection rectangular lower magnet, lower magnet adhesive upper magnet again, facilitates insulating bar and upper magnet
Separate.Equipped with binding post in upper magnet, conveniently connect measurement line.Top crotch can be fixed firmly on cable conductor.
