Shanghai is even more to stand in the breach as the engine of Chinese Economy Development.So the construction quantity of transformer station is just in geometry level in recent years
Several increases.Nearly 1 year, only by taking the Pudong New District in Shanghai as an example, capital construction was put into operation 4,110kV transformer stations totally, and 10kV switchyards are total to
More than 30, transform totally 3, the 110kV transformer stations that put into operation, totally 5,35kV transformer stations.
But a large amount of newly-built transformer station Xin Cang put into operation, or the transformer station of transformation needs to install longitudinal difference protection additional, is required to
Relay protection personnel's convection current Variable Polarity is determined, that is, is needed to carry out poor pole mutually to test and tested, to verify that the phase sequence of A, B, C phase is accurate
Property.In the prior art, carry out poor pole and mutually test to test to need relay protection personnel to open transformer station position in storehouse back shroud, above and below rheology
Wiring is distinguished in termination, is passed through electric current, rheology polarity is determined by inductive current direction in secondary side.But due to Hou Cang spaces
Narrow and small, position is relatively low, and relay protection personnel generally require to lie on the floor, on the basis of sight can not be removed and see bus bar clearly,
With hand gropingly could accurate clamp, cause operation to be wasted time and energy, a bin level generally requires several minutes could be good by wire clamp；Together
When be easy to touch rheology non-insulated portion, potential safety hazard be present.
Based on a kind of above-mentioned, visual extension fixture for relay protection verification of present invention proposition, to solve to deposit in the prior art
The shortcomings that and limitation.
The content of the invention
It is an object of the invention to provide a kind of visual extension fixture of relay protection verification, operating personnel and bus bar are effectively avoided
The direct contact of non-insulated portion, prevents electric shock risk；The blind area of naked eyes can be seen clearly in real time simultaneously, improve processing safety
And convenience, and improve the efficiency of accurate wiring.
To achieve the above object, the present invention provides a kind of visual extension fixture of relay protection verification, comprising：Metal clip, it is used for
The cable clamped on bus bar carries out relay protection verification, and the metal clip is internally provided with the checkout line being connected with clip tooth；It is miniature to take the photograph
Picture head, it is fixedly installed on the top of metal clip, the video of shooting operation personnel blind area in relay protection checking procedure；It is hollow to prolong
Long tube, it is connected with the tail end of metal clip, its inner containment checkout line；Hollow operations handle, it is connected with hollow extension tube, inside it
Checkout line is accommodated, checkout line is extended export after sequentially passing through hollow extension tube and hollow operations handle.
Described metal clip is made of stainless steel material.
Lighting unit is provided with described minisize pick-up head.
Connected between described metal clip and hollow extension tube using Hooks coupling universal coupling.
Further, described Hooks coupling universal coupling uses cross axle type coupling.
Described hollow operations handle, which is adopted, to be made from an insulative material.
Data-interface is provided between described hollow extension tube and hollow operations handle, passes through data wire and miniature video camera
Head connection, the image that the data-interface shoots satellite camera export in real time.
Described data wire is passed through by the inside of hollow extension tube and is connected to data-interface.
In summary, the visual extension fixture of relay protection verification provided by the invention, when relay protection verification operation personnel are in position in storehouse
When carrying out relay protection verifying work, clamp operation can be carried out by the hollow operations handle extended by hollow extension tube, effectively avoided
Operating personnel directly contact with bus bar metal part, prevent electric shock risk；Simultaneously by scheming in real time derived from minisize pick-up head
Blind area as seeing the naked eyes such as the rheology back side, bus bar top clearly, effectively improves processing safety and convenience.
