Description

A Portable Pole Switch Test Platform

technical field

The utility model belongs to the technical field of high voltage test, in particular to a portable switch test platform on a pole.

Background technique

The operating mechanism of the switch on the column is generally located on the base of three fractures. With the development of miniaturization of the structure design, if the switch on the column is placed on the ground, the size of the mechanism box is not enough to ensure the rotation of the manual operating rod in place, and the secondary circuit of the switch will be aeronautical. The terminal is located at the base of the mechanism box, which is not convenient for test operation and test wiring. The main body of the switch on the pole weighs about 200kg. For the test of uninstalled equipment, the whole process needs to be hoisted, which is inefficient and expensive.

Contents of the invention

The purpose of the utility model is to overcome the deficiencies of the prior art, and provide a portable pole-mounted switch test platform with reasonable design, convenient use, high efficiency and low cost.

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

A portable pole-mounted switch test platform, including a working table, an insulating support plate and platform feet, the middle of the working table is a load-bearing metal plate, and the front and rear are hollow blocks respectively; the insulating support plate can be folded and installed on the working table At both ends, the outer edge of the insulating support plate is a regular curved edge; the platform legs are metal rods and can be folded and installed at the four corners of the bottom of the worktable, and the lower end of each platform leg is provided with pulleys and anti-sliding blocks.

Moreover, the insulating support plate is installed together with the work table through the insulating support plate hinge.

Moreover, the platform support feet are installed together with the work surface through the platform support foot hinges.

Advantage and positive effect of the present utility model are:

1. The test platform can be easily moved through the pulleys at the bottom of the platform feet. After moving to the designated point, press down the anti-sliding block to realize the function of stabilizing the platform; in addition, the platform feet can be folded by hinges to reduce storage and transportation space .

2. The working table of this test platform is made of metal material to ensure the zero potential of grounding, and at the same time it can bear at least 300kg of weight. , to facilitate the connection of the control circuit; the test platform is at a certain height from the ground, which is convenient for the test personnel to test the wiring and manual switch operation.

3. When the insulating support plate of this test platform is erected, the cables at both ends of the switch on the support column are curved, which avoids the sliding of the cable, and does not stretch the bent cable at the same time to avoid damage to the joints. The insulation strength of the insulating support plate It can withstand the AC withstand voltage of the switch on the pole; the insulating support plate can be folded by hinges, reducing storage and transportation space.

Among them, 1—working table, 2—insulating support plate, 2.1—insulating support plate hinge, 3—platform leg, 3.1—pulley, 3.2—slip block, 3.3—platform leg hinge.

Detailed ways

Below in conjunction with accompanying drawing, the utility model embodiment is described in further detail:

A portable pole-mounted switch test platform, as shown in FIG. The working surface is a "mesh"-shaped metal plate, and the middle is a load-bearing metal plate that should be reliably grounded during the test; the two ends are hollowed out blocks, and the wiring and operation can be started from the hollowed out place. The insulating support boards are two foldable insulating support boards, and the two foldable insulating support boards are respectively installed on both ends of the worktable through the insulating support board hinge 2.1. The width of the insulating support boards is consistent with the width of the table top. The length can withstand the voltage of AC52kV. The corresponding wide side of the insulating support board is the same straight line as the table top, and the other side is a regular curved side; when the insulating support board is erected for testing, the curved side supports 6 ends of the switch for about 2 meters The long cable is convenient for the withstand voltage test; when it needs to be transported, the insulating support plate can be folded through the hinge to reduce the storage and transportation space. The platform legs are four foldable metal rods, the upper end of each metal rod is set as a platform leg hinge 3.3, the lower end of the metal rod is provided with a pulley 3.1 and a slip block 3.2, and the upper end of the platform leg is hinged to the work surface through the platform leg hinge. At the same time, the pulley at the lower end of the platform foot is the contact point between the platform foot and the ground, and the pulley is attached with a stop block; the test platform can be easily moved through the pulley, and the test platform can be stably fixed on the ground through the stop block, which can be adjusted conveniently.

It should be emphasized that the embodiments described in the utility model are illustrative rather than restrictive, so the utility model includes but not limited to the embodiments described in the specific implementation, and those skilled in the art according to the utility model Other implementations derived from the new technical solution also belong to the scope of protection of the utility model.
