Description

A high-voltage switch cabinet circuit breaker plum-blossom contact disassembly and installation tool

technical field

The utility model relates to the technical field of high-voltage electrical auxiliary equipment, in particular to a disassembly and installation tool for a plum-blossom contact of a circuit breaker in a high-voltage switch cabinet.

Background technique

In the prior art, during the operation of the high-voltage switchgear, due to the size of the load, the current flowing through the circuit breaker of the switchgear varies. When the load is larger, the operating current is larger. The contact parts of the cabinet’s dynamic and static contacts bite will cause heat due to poor contact. In severe cases, the circuit breaker contacts may be burned, which may cause arc grounding short-circuit or phase-to-phase short-circuit faults in the switch cabinet, resulting in serious consequences. Inspection, maintenance, overhaul. Most of the time, the maintenance personnel use a cross or flat-blade screwdriver with needle-nose pliers to disassemble and install the plum-blossom contact of the circuit breaker of the high-voltage switchgear, and two people are required to cooperate. , which is time-consuming, labor-intensive and unsafe.

Utility model content

The purpose of the utility model is to overcome the deficiencies of the prior art, and to provide a safe, time-saving and labor-saving device that does not use a cross or flat-blade screwdriver with needle-nose pliers to dismantle, when inspecting, maintaining, and repairing the plum-blossom contact. Removal and installation tool for plum-blossom contacts of high-voltage switchgear circuit breakers with plum-blossom contacts installed.

The technical solution provided by the utility model to solve the above problems is to provide a high-voltage switchgear circuit breaker plum-blossom contact disassembly and installation tool, which is characterized in that it includes a positioning disc, a pliers hook, a handle, a rotating handle, and a fixed pliers hook. Connecting rod, rotating screw, round cover; clamp hook, fixed clamp hook connecting rod, fixed connection of handle; integral connection of rotating handle and rotating screw; threaded connection between rotating screw and fixed clamp hook connecting rod; round cover and positioning The disc and the rotating handle are movably connected; the positioning disc is fixedly connected with the rotating screw rod and the rotating handle. The utility model is further characterized in that: the pliers-shaped hook, the connecting rod of the fixed pliers-shaped hook, and the handle are connected by threads. The dome cover is movably connected with the positioning disc and the rotating handle through the screw thread.

The beneficial effect of the utility model is that the plum-blossom contact can be disassembled and installed by a single person, and the tool is simple and safe to use.

Description of drawings

Fig. 1 is the longitudinal sectional structure diagram of the embodiment of the present utility model;

FIG. 2 is a top view of an embodiment of the present invention.

In the accompanying drawings: 1. Positioning disc; 2. Clamp-shaped hook; 3. Handle; 4. Rotating handle; 5. Fixed clamp-shaped hook connecting rod; 6. Rotating screw rod; 7. Round cover.

Detailed ways

The present utility model will be described in further detail below in conjunction with the accompanying drawings and embodiments. A tool for disassembling and installing the plum-blossom contact of a circuit breaker in a high-voltage switchgear; as shown in Figure 1 and Figure 2: including a positioning disc 1, a clamp hook 2, a handle 3, a rotating handle 4, a fixed clamp hook connecting rod 5, a rotating Screw 6, round cover 7; clamp hook 2, fixed clamp hook connecting rod 5, handle 3 threaded connection; rotating handle 4, rotating screw 6 fixed connection; rotating screw 6 and fixed clamp hook connecting rod 5 threaded connection; The screw 6 can advance clockwise and exit counterclockwise; the round cover 7 is movably connected between the lower part of the positioning disc 1 and the rotating handle 4 . The dome 7 is movably connected with the positioning disc 1 and the rotating handle 4 through the rotating screw 6 . The working principle of the utility model is as follows: when disassembling the plum-blossom contact, a plier-shaped hook 2 is used to hook the plum-blossom contact spring pressing piece to connect the ring, the maintenance personnel hold the handle 3 with one hand, and rotate the rotary handle 3 clockwise with the other hand. The rotating screw 6 moves forward, so that the positioning disc 1 bears against the conductive arm of the circuit breaker fixing the plum-blossom contact, while the dome covers the plum-blossom contact conductive sheet by about 20mm, so that the plum-blossom contact pressure spring opens out 5 -6mm, so as to remove the plum blossom contact; when installing, on the contrary, first make the pliers hook hook the plum blossom contact spring pressing piece to connect the ring, turn the handle screw clockwise to move forward, when the dome cover 7 covers When the conductive piece of the plum-blossom contact is about 20mm, the compression spring of the plum-blossom contact opens outward by 5-6mm, then install the contact on the conductive arm, and rotate the handle 3 and the rotating screw 6 counterclockwise to move backward until the tool clamp hook 2 Naturally disengage the plum blossom contacts.
