Description

A special test line clamp rod with an early warning device

technical field

The utility model belongs to the technical field of electrical testing equipment, in particular to a special-purpose line clamp rod for testing with an early warning device.

Background technique

Primary equipment is the core equipment in the substation. Since the implementation of condition-based maintenance, routine and diagnostic tests have replaced traditional test methods and become the main means today. In the implementation of equipment survey, there are survey work on high-altitude equipment. During the measurement, it is necessary for the test personnel to climb to the maintenance equipment table to perform the clamping operation, which is time-consuming and labor-intensive, and poses a great safety hazard. When it climbs to a high place, according to the safety belt clearly stipulated in the "Safety Regulations", it needs to be hung high and used low, but this is often not possible on primary equipment. Existing safety barriers only play a warning role visually, and are deficient in other aspects.

Contents of the invention

The purpose of this utility model is to propose a kind of test special line clamp bar with early warning device in view of the deficiencies of the prior art.

The utility model solves its technical problem and realizes by taking the following technical solutions:

A special line clamp rod for testing with an early warning device, including a concave clamp frame with an opening to the left, a tongue plate lower branch pipe is installed in the middle of the lower bottom plate of the concave clamp frame, and a tongue plate is inserted into the upper opening of the tongue plate lower branch pipe On the plate support, the tongue plate for clamping wires is fixed on the top of the tongue plate support, on the outside of the tongue plate lower branch pipe and the tongue plate support, the fastening spring is set and fixed between the tongue plate and the lower bottom plate of the clamp frame, The left end of the tongue plate is integrally made with a downwardly curved tongue plate head, the left end of the upper plate of the concave clamp frame is an upwardly curved lead plate head, and an electrically connected crocodile wire clip is welded on the right side of the concave clamp frame. The lower end of the crocodile clamp is formed with a wire connection seat, the end of the wire drawn from the wire connection seat is formed with a plug, and a downward connecting rod column is integrally formed at the bottom of the concave clamp frame. The near electric early warning device is fixedly installed, and the upper end of the insulating telescopic rod is screwed on the lower end of the connecting rod column, and the upper end of the insulating telescopic rod is plugged into the inside of the hand-held insulating rod and fixed by rotation.

Moreover, teeth are formed on the lower surface of the upper plate of the concave clamp frame and the upper surface of the tongue plate.

Advantage and positive effect of the present utility model are:

1. The practical effect of the utility model is good: the special line clamp rod for the test solves the problem of potential safety hazards in high-altitude operations;

2. The effect of the utility model is convenient and obvious: the test special line clamp rod can be adjusted, detachable and replaceable, which is suitable for the detection of different heights, different equipment, and different test items, reducing the need for carrying ladders and wearing safety belts during operation. Auxiliary tools can improve the overall efficiency of the test work and have a wide range of applications, simple and practical;

3. The safety factor of the utility model is improved: the special line clamp rod for the test is equipped with an alarm, which generates a buzzer sound during the pressurization process, which effectively plays the role of "sound blocking" and warns the surrounding personnel to pay attention to safety during the pressurization process. near;

4. The utility model is convenient to operate: the special line clamp rod for the test is beneficial to the ground operation of the test operator, and the personnel do not need to climb to a high place, and the routine and diagnosis of the main circuit resistance, leakage current detection, dielectric loss, etc. can be realized on the ground The measurement of the item. The strong combination of its built-in sound alarm and the safety barrier on the ground enables the surrounding people to play an effective warning function from both vision and hearing, and improves the safety factor.

Detailed ways

The implementation of the utility model will be described in further detail below in conjunction with the accompanying drawings. The following examples are only descriptive, not restrictive, and cannot limit the protection scope of the utility model.

A kind of special line clamp rod for testing with early warning device, as shown in Figure 1, includes a concave clamp frame 4 with the opening facing to the left, a tongue plate lower branch pipe 11 is installed in the middle of the bottom plate of the concave clamp frame, and a tongue plate lower branch pipe 11 is installed under the tongue plate. The tongue plate pillar 9 is inserted into the upper opening of the branch pipe, and the tongue plate 8 for clamping wires is fixed on the top of the tongue plate pillar, and the sleeve is fixed on the tongue plate and the clip on the outside of the tongue plate lower branch pipe and the tongue plate pillar. The fastening spring 10 between the lower bottom plates of the frame, the left end of the tongue plate is integrally made with a downwardly curved tongue plate head 5, and the left end of the upper plate of the concave clamp frame is an upwardly curved lead plate head 6, and the tongue plate head Align with the left side of the lead plate head and open outwards to form a lead-in opening for clamping wires in. On the right side of the concave clip frame, there is an electrically connected crocodile clip 12 for connecting equipment experiment wires. At the lower end of the crocodile clip Be shaped on lead connecting seat 13, the end of the lead wire 15 that lead connecting seat draws is shaped on plug 16, is integrally formed with downward connecting rod column 14 at the bottom end of concave-shaped clamping frame, through the insulation on the side of connecting rod column The post is equipped with a near electric early warning device 3, and the lower end of the connecting rod column is screwed with an upper insulating telescopic rod 2, and the upper insulating telescopic rod is plugged into the inside of the hand-held insulating rod 1 and fixed by rotation.

In the specific implementation of the utility model, teeth 7 are formed on the lower surface of the upper plate of the concave clamp frame and the upper surface of the tongue plate, and the teeth are used to grasp the wires and maintain a good electrical connection.

working principle
