The fastening buckle is firmly connected with the equipment through two clips, and the elastic clamp mouth supports and fixes the multimeter. The operator only needs to rotate the elastic universal rod according to the space and angle to play a good supporting role, fully liberating The hands of the personnel are free, and the stability of the support is strong; the disadvantages of the traditional multi-person coordinated operation are changed, and the work efficiency is qualitatively improved.

Description

Substation secondary circuit fault multimeter auxiliary inspection tool

technical field

The utility model belongs to the technical field of secondary circuit fault inspection auxiliary tools for substations, and in particular relates to an auxiliary inspection tool for multimeters for substation secondary circuit faults.

Background technique

In the prior art, the substation secondary circuit system has a lot of equipment, cables, terminals, protective pressure plates, etc., the fault location is varied, and the fault phenomenon is strange. The secondary circuit is an important part of the electrical system. Failure of the secondary circuit will directly affect the safe operation of electrical equipment and power systems, and even cause extremely serious consequences. A clear understanding of the site situation, familiarity with the professional knowledge of electrical equipment, and proficiency in the testing skills of using multimeters can be handy in the work.

Using a multimeter can accurately and quickly find faults. There are mainly three inspection methods: the method of measuring continuity, the method of measuring voltage drop, and the method of measuring ground potential; This method can be used for live measurement, but regardless of the inspection method, it is necessary to manually hold the multimeter for operation. Since there is no professional tool to fix the multimeter, it is very inconvenient for a single person to hold the inspection equipment, and it is generally coordinated by multiple people; moreover, hand-held inspection equipment The personnel need to hold it stably, and the operation process is even more inconvenient in places with limited space, which restricts work efficiency; therefore, it is imperative to develop a supporting auxiliary tool to facilitate the fault inspection process.

Contents of the invention

The purpose of the utility model is to solve the above-mentioned technical problems of inconvenient operation by a single person and low work efficiency, and provide an auxiliary inspection tool for a multimeter for substation secondary circuit faults, so as to overcome the deficiencies in the prior art.

In order to achieve the above purpose, the utility model is an auxiliary inspection tool for a substation secondary circuit fault multimeter, which includes an elastic clip and a fastening buckle; the two clips provided on the fastening buckle are mutually connected by fastening bolts Fastened by wire connection; the rear end of the fastening bolt is fixedly connected to one end of the elastic universal rod; the other end of the elastic universal rod is provided with a steering knuckle ball, and the steering knuckle ball and the bottom of the elastic clip The steering bases are snapped together with each other.

Further, an elastic rubber pad is provided on the inner side of the elastic clamp mouth corresponding to the clamping position.

The utility model has reasonable structural design and is easy to use. The fastening buckle is fastened and connected with the equipment through two clips. It can play a good supporting role, fully liberate the hands of personnel, and has strong support stability; it has changed the disadvantages of traditional multi-person coordinated operation, and the work efficiency has been qualitatively improved. The utility model solves the technical problems of inconvenient single-person operation and low work efficiency in the prior art.

detailed description

Referring to Fig. 1 and Fig. 2, the utility model includes an elastic clamp mouth 1 and a fastening buckle 6; the two clips provided on the fastening buckle 6 are fastened with each other by fastening bolts 5; The rear end of the fastening bolt 5 is fixedly connected to one end of the elastic universal rod 4; The steering base 2 is engaged with each other in a movable manner.

Further, an elastic rubber pad is provided on the inner side of the elastic clamp mouth 1 corresponding to the clamping position.

Working principle: The elastic clamp mouth 1 is used to support and fix the multimeter, the fastening buckle 6 is used to clamp and connect with the equipment, the elastic universal rod 4 plays the role of support and can be adjusted at any angle, the operator only needs to hold the multimeter with elastic It only needs to be held by the clamp, the hands are freed, and the stability is strong, which ensures the accuracy of the inspection process data and improves the work efficiency.

The utility model has a reasonable design, realizes the expanded use of the multimeter, solves the technical problems of time-consuming and labor-intensive field search for secondary circuit faults, and low work efficiency, and is suitable for equipment such as substation terminal boxes or switch cabinets.
