The anti-fall clamping device of device lead, belongs to large-scale power transformer equipment technical field.
Background technology
In the structure of large-scale power transformer, high-tension coil head end is connect by lead and casing from inside transformer extraction
Line is to power distribution equipment.The 500kV leads of 500kV single-phase transformers are since voltage class is high, electric field strength is big, from high-tension coil
After portion is drawn, balance pipe protection need to be applied mechanically, with balanced voltage, improves lead field strength distribution, until lead enters casing and presses
In ball.Since balance pipe is since winding protruding head root, there are multi-layer forming square ring and insulating paper cylinder package protection in outside, makes outside it
Footpath and weight are larger, such as it is fixed it is improper it is easy leads to the problem of tenesmus, and then cause balance pipe goal insufficient and square ring, insulating paper
Cylinder damages or even stretches terminal plate under pipe of helping pull a cart, and the electrical strength and mechanical connection to 500kV leads bring hidden danger, thus cause
Transformer fault precedent it is commonplace.
Referring to the drawings 1, traditional 500kV large-scale power transformer lead method of clamping is：Using standing in bottom feet
Insulating supporting structure support voltage equalizing ball, voltage equalizing ball and balance pipe be an integral molding structure, and it is loudspeaker to enter above voltage equalizing ball at casing
Mouth shape insulating cylinder, electrion caused by climbing electricity to protection tube end electrical body and insulator, whole is in goblet shape,
Pressure ball body is clamped by the conductor grip and cardboard drawstring being fixed on device body screen.With the continuous renewal of transformer technology and drop originally
The drawbacks of pressure of synergy continues to increase, this structure gradually shows and increasing：1）500kV leads and voltage equalizing ball are whole outer
The molded insulator of purchase, purchase cost are growing；2）The voltage equalizing ball that 500kV casings carry cannot use, and be put in storage after removing not busy
It puts and causes cost and waste spatially；3）Voltage equalizing ball and conductor grip assembling are complicated, and stent is bulky, and installation and adjustment operation is numerous
It is trivial, time-consuming and laborious.
Utility model content
The utility model aim is to provide a kind of anti-fall clamping device of large-scale power transformer lead, and lead can be avoided equal
The tenesmus of pressure pipe and topple over problem, can reliably be installed in place, improve insulation mechanical strength, solve to exist in background technology
The problem of.
The technical solution of the utility model is：
A kind of anti-fall clamping device of large-scale power transformer lead comprising voltage equalizing ball, drawstring, conductor grip, lead, is pressed
Pipe, insulation board and device body screen, lead are located in balance pipe, and the balance pipe includes vertical section and horizontal segment, vertical section and water
Flat section is integrally formed L-shaped, and one end of the vertical section of balance pipe is stretched into voltage equalizing ball, and one end of drawstring is fixed on the perpendicular of balance pipe
On straight section, the other end of drawstring is fixed on device body screen, and insulation board is fixed on the horizontal segment of balance pipe, one end of conductor grip
It is rotatablely connected with device body screen, the other end of conductor grip is fixedly connected with insulation board.
The drawstring is fixed on by shrinkage band on device body screen.
The balance pipe is aluminum L-type pipe.
Using the utility model, eliminate and stood in traditional anti-fall clamping device of high-power transformer lead in bottom feet
Insulating supporting structure, lead balance pipe is gripped using the drawstring and conductor grip that are fixed on device body screen, can
Fully extend vertically into inside voltage equalizing ball, and can be abundant in the certain assembling of lead left and right directions offer by the rotation of conductor grip
Degree, avoids the tenesmus of lead balance pipe and topples over problem.
The beneficial effects of the utility model are：It efficiently solves the tenesmus of large-scale power transformer lead balance pipe and inclines
Inverse problem, can reliably be installed in place, and both ensure that the electrical strength between balance pipe and lead and voltage equalizing ball and insulation
Distance in turn simplifies structure, improves insulation mechanical strength, while facilitates installation operation, saves material, material and people
Power.
