Description

Concrete single-rod drop-out fuse cross arm of double-loop current collection circuit

Technical Field

The utility model relates to a fuse cross arm, specifically speaking are concrete single pole drop out fuse cross arm of two return circuits collection circuit belongs to fuse cross arm field.

Background

Along with the continuous improvement of socioeconomic development level, the development of electric power system has been enlarged rapidly, and overhead line often can select cable terminal access transformer substation because of the corridor is not enough when arriving at a station, in order to create a safe operational environment for later stage maintenance section circuit and equipment, just at this moment need install subsidiary facility on the terminal pole, if: a drop-out fuse. The facility is usually installed after a concrete pole is erected, how to install two groups of drop-out fuses on a concrete single pole simultaneously and ensure that the two groups of drop-out fuses and the concrete single pole can be firm and attractive, and no solution exists.

In a conventional installation method, two sets of single-circuit drop-out fuse cross arms are installed on a concrete pole after the concrete pole is erected. Because two sets of single-loop drop-out fuse cross arms are installed, the length of a drainage wire is increased under the limitation of operating conditions and equipment distance, and a post insulator and the cross arms thereof are required to be added for preventing the wire from galloping, so that the appearance is influenced, the weight of a concrete pole is increased, and some equipment is required to be matched therewith, so that the construction cost is increased.

Disclosure of Invention

In order to solve the problem, the utility model discloses a two return circuits collection circuit concrete single pole drop out fuse cross arm can realize being connected reliably with the concrete single pole simultaneously two sets of drop out fuses, reduces the weight on the concrete pole, reduces construction cost to reach firm, pleasing to the eye purpose.

The technical scheme of the utility model is that: the utility model provides a two return circuit current collection circuit concrete single pole drop out fuse cross arm, includes U type staple bolt, cross arm angle steel, band iron, fixed band iron, props indisputable angle steel, props indisputable staple bolt and bolt, the bolt includes first bolt, second bolt, third bolt, fourth bolt and fifth bolt, band iron and fixed band iron are fixed on the cross arm angle steel with the welded mode, the cross arm angle steel is fixed on the concrete pole by U type staple bolt, the cross arm angle steel still is connected with propping indisputable angle steel through first bolt and second bolt, the third bolt is fixed on propping indisputable staple bolt with the welded mode, prop indisputable angle steel and pass through the third bolt and be connected with propping the indisputable staple bolt, prop the indisputable staple bolt and pass through fourth bolt and fifth bolt fastening on the concrete pole.

Preferably, the cross arm angle steel is provided with four screw holes.

Preferably, the flat iron is provided with two screw holes.

Preferably, the angle iron of the supporting iron is provided with two screw holes.

After the technical scheme is adopted, the beneficial effects of the utility model are that:

1. two sets of single-loop drop-out fuse cross arms are not required to be arranged on the concrete single rod, so that the two sets of drop-out fuses can be reliably connected with the concrete single rod;

2. simple structure, the installation is succinct, and operation and maintenance are convenient, have reduced weight and construction cost on the concrete pole simultaneously.
