Abstract

The utility model relates to a novel transformer lead clamping element, and belongs to the technical field of transformer equipment. According to the technical scheme, the novel transformer lead clamping element comprises a first clamping element body (1), a second clamping element body (2), an upright rod (3) and a cable (4), wherein one end of the first clamping element body (1) is fixedly connected with the upright rod (2) through a bolt, the other end of the first clamping element body (1) is connected with the second clamping element body (2), the thickness of the end, connected with the upright rod (3), of the first clamping element body (1) is larger than that of other portions of the first clamping element body, other portions of the first clamping element body are of a linear structure, the bending arc of the second clamping element body is matched with the diameter of the cable (4), and the cable is arranged between the first clamping element body and the second clamping element body. The novel transformer lead clamping element has the advantages that due to improvement of the structure of the clamping element, the thickness of the clamping element is reduced, slotting is eliminated, mechanical strength of the lead clamping element is effectively improved, the mechanical distance between the clamping element and an oil tank is correspondingly shortened, the number of the clamping element bodies is reduced, production cost is reduced, and good economic benefits and social benefits are achieved.

Description

A kind of novel transformer cable guide gripping member

Technical field

The utility model relates to a kind of novel transformer cable guide gripping member, belongs to the transformer equipment technical field.

Background technology

After completing, the transformer manufacture needs through long-distance transport to infield, transformer in service can bear the percussion of various overvoltage and power grid accident short circuit current, therefore to guarantee that lead-in wire has enough mechanical strengths, also should meet the needs of electrical distance and anti-short circuit capability.

For high voltage, products with larger capacity, because the diameter of lead-in wire is larger, have or even several cables are combined use, according to traditional clamp method, need on holder, slot with the positioning cable line, because the cable diameter is large, the holder fluting is larger, and then increase the thickness of holder, and consider the nargin of mechanical distance and corresponding installation, oil tank of transformer also increases accordingly.

In addition, traditional structure clamps cable, considers the requirement of mechanical strength of holder, also needs additionally to increase a transition clamp gripping member, corresponding increase securing member.

From economic angle, traditional approach can increase the manufacturing cost of transformer undoubtedly, causes unnecessary waste.

The utility model content

The utility model purpose is to provide a kind of novel transformer cable guide gripping member, reduce by holder thickness, cancel fluting, effectively increased the mechanical strength of cable guide gripping member, the corresponding mechanical distance of holder to fuel tank of dwindling, solve the problems referred to above that exist in background technology.

The technical solution of the utility model is: a kind of novel transformer cable guide gripping member, comprise holder one, holder two, vertical rod and cable, one end and the vertical rod of described holder one are bolted to connection, the other end and holder two are connected to each other, holder one is greater than the thickness of other parts at the end thickness be connected with vertical rod, other parts are rectilinear structure, and the crooked radian of holder two and the diameter of cable are complementary, and cable is arranged between holder one and holder two.

Drawing materials as the paperboard pieces material of described holder two.

The beneficial effects of the utility model are: by the transformation of holder structure, holder thickness is reduced, cancel fluting, effectively increased the mechanical strength of cable guide gripping member, the corresponding mechanical distance of holder to fuel tank of dwindling, reduce the quantity of holder, reduced manufacturing cost, there is good economic benefit and social benefit.
