The invention has the beneficial effects that: the utility model is convenient to install and firm in fixation, is not limited by the size of the bolt, improves the safe and stable operation of the power system, can firmly buckle the whole jointing clamp on the flange of the mutual inductor, and avoids the conditions of looseness and poor contact; the wiring clamp has the characteristics of simplicity in operation, high clamping force, good contact, high practicability and the like, is particularly suitable for testing various mutual inductor devices, and has the service life of more than 5 years.
Description
Technical Field
The invention relates to the field of transformer equipment maintenance, in particular to a portable electrical test flange wiring clamp.
Background
The experimental wiring of mutual-inductor uses in present transformer substation mostly with experimental clamp, and this experimental clamp volume is less, breakable, yielding, and uses for a long time and can cause the condition of pressing from both sides insecure, and differs because of the size to the mutual-inductor of different grade type, need prepare the unequal multiple test of size and press from both sides, and preparation work also can add work load, and the maintenance cost also can increase thereupon. Because the size of the connecting bolt can be directly influenced by the diameter of the flange, the bolt can not be firmly clamped by the test clamp in daily tests, slight shaking can cause the clamp to be disengaged, and unqualified contact test results can be caused.
SUMMERY OF THE UTILITY MODEL
Aiming at the defects of the prior art, the invention provides a portable electrical test flange wiring clamp which is characterized in that: the two semicircular buckles and the movable pliers are integrally formed, the two semicircular buckles are arranged at two ends of the movable pliers respectively, a spring is arranged between two ends of the movable pliers, two ends of the spring are buckled at the inner sides of two arms of the movable pliers, the bottom of the movable pliers is connected with a wiring pliers buckle in a welding mode, and a wing-shaped nut is arranged at the movable end of the wiring pliers buckle.
And the upper side and the lower side in the semicircular buckle are respectively provided with an anti-skidding tooth trace, and the anti-skidding tooth trace and the semicircular buckle are integrally formed.
The width of the semicircular arc buckle is 50mm-60mm, and the width of the movable clamp is 110mm-120 mm.
The semicircular buckle, the anti-skid tooth trace, the movable clamp and the wiring clamp buckle are all made of stainless steel.
The principle and the using method of the invention are as follows: a telescopic insulating rod is additionally arranged in the wiring clamp buckle, and the semicircular buckle is buckled on a flange between the two transformers for testing.
The invention has the beneficial effects that: the utility model is convenient to install and firm in fixation, is not limited by the size of the bolt, improves the safe and stable operation of the power system, can firmly buckle the whole jointing clamp on the flange of the mutual inductor, and avoids the conditions of looseness and poor contact; the wiring clamp has the characteristics of simplicity in operation, high clamping force, good contact, high practicability and the like, is particularly suitable for testing various mutual inductor devices, and has the service life of more than 5 years.
