Abstract

The utility model relates to a special insulating bolt wrench for assembly of a transformer and belongs to the technical field of manufacturing of transformers. The technical scheme is as follows: the special insulating bolt wrench comprises a wrench head (1) and a wrench handle (2); the wrench head and the wrench handle are made of wood material and are integrated; the included angle between the wrench head and the wrench handle is 100 to 175 degrees; the special insulating bolt wrench is suitable for being used for assembling a transformer in a narrow space. The special insulating bolt wrench has the positive results that the weight of the bolt wrench is about one tenth of a common wrench same as the bolt wrench in size, so that the operation is more convenient; an included angle is formed between the wrench head and the wrench handle, so that the bolt wrench is more suitable for assembly in a narrow space, and then convenience is provided for operators; the bolt wrench adopting a wood structure can avoid the problem that metal pieces or metal chips are left on devices and does not threaten the devices, so that quality problems can be avoided.

Description

A kind of transformer assembling special isolation track wrench

Technical field

The utility model relates to a kind of transformer assembling special isolation track wrench, belongs to technical field of transformer manufacturing.

Background technology

At present, in the transformer assembling process, limited by assembly space, the insulated bolt at a lot of positions can't assemble with the common metal spanner, and there is Heavy Weight in the metal spanner, be awkward, can cause metalwork to leave over the problem of device body, when assembling is inconvenient, the quality of transformer is also produced to threat.

The utility model content

The purpose of this utility model is to provide a kind of transformer assembling special isolation track wrench, for the assembling of transformer narrow space insulated bolt, when improving efficiency of assembling, has eliminated hidden danger of quality, solves the problems referred to above that background technology exists.

The technical solution of the utility model is:

A kind of transformer assembling special isolation track wrench, comprise spanner and trigger piece, and the spanner and the trigger piece that are wood materials are as a whole, and the angle between spanner and trigger piece is the 100-175 degree, is adapted at the assembling of transformer narrow space and uses.

Described spanner and trigger piece are spanner and the trigger piece of electrical laminated wood.Maximum innovative point of the present utility model is spanner and the parallel design that trigger piece breaks traditions, and a 100-175 degree angle is arranged between spanner and trigger piece, can farthest adapt at the transformer narrow space and carry out assembly manipulation.

The spanner of electrical laminated wood and trigger piece, hardness is relatively large, can meet insulated bolt assembling requirement of strength; The density of electrical laminated wood is 0.8g/cm3, and the density of iron is 7.8g/ cm3.

Good effect of the present utility model: weight of the present utility model is approximately 1/10th of equal-volume common wrench, operates lighter; An angle is arranged between the utility model spanner and trigger piece, be more suitable for, at the narrow space assembly manipulation, offering convenience to the operator; Wooden structures does not exist metalwork or metal fillings to leave over the problem of device body, and insulation does not constitute threat to the device body, can avoid the generation of quality problems.

The accompanying drawing explanation

Fig. 1 is the utility model embodiment schematic diagram;

In figure: spanner 1, trigger piece 2, angle 3.

The specific embodiment

Below in conjunction with accompanying drawing, by embodiment, the utility model is described further.

A kind of transformer assembling special isolation track wrench, comprise spanner 1 and trigger piece 2, and the spanner and the trigger piece that are wood materials are as a whole, and the angle between spanner and trigger piece is the 100-175 degree.

Through the actual use of operator, the utility model is more suitable for using when the transformer narrow space assembles than common metal spanner, because its material is wooden, the light characteristics of operation is arranged, simultaneously can not cause metalwork or metal fillings to leave over the problem of device body, be adapted at transformer manufacture technology and promote the use of.

Claims

1. a transformer assembles the special isolation track wrench, and it is characterized in that: comprise spanner (1) and trigger piece (2), the spanner and the trigger piece that are wood materials are as a whole, and the angle between spanner and trigger piece is the 100-175 degree.

2. a kind of transformer according to claim 1 assembles the special isolation track wrench, and it is characterized in that: described spanner and trigger piece are spanner and the trigger piece of electrical laminated wood.
