Description

Technical Field

[0001] The utility model relates to the technical field of low-voltage lightning arrester testing, in particular to a low-voltage lightning arrester testing tool. Background Art

[0002] At present, the low-voltage lightning arrester test is only implemented by a test machine. The high-voltage and low-voltage ends of the machine need to be connected to the two test ports of the lightning arrester. The operation process is relatively cumbersome. Using work piles to assist in the test can omit this step and reduce the connection between the high and low voltage ends of the lightning arrester. When the number is large, the test process is too complicated. The existing technology requires manual labor to hold the two ends of the test machine to test the low-voltage lightning arrester. Each test requires the clips to be removed and then connected to the new lightning arrester. In the previous test process, it is necessary to manually take the clips on both sides of the high and low voltage, and the test tooling has obvious discharge during the test. Therefore, there is a risk of electric shock for the tester during the test, which is prone to direct safety hazards. Utility Model Content

[0003] In order to solve the above-mentioned technical defects, the purpose of the utility model is to provide a low-voltage lightning arrester test tool, which can effectively avoid the risk of electric shock for testers during the test process and the direct safety hazard caused by this, thereby solving the problem that during the test process, the test tool has obvious discharge phenomenon during the test, but needs to manually take the clamps on both sides of the high and low voltage.

[0004] To achieve the above-mentioned purpose, the utility model provides a technical solution: a low-voltage lightning arrester testing tool, including a tray body and a bottom plate, a base is installed on the top of the bottom plate, an insulating rod is inserted inside the base, a mounting hole is opened inside the bottom end of the insulating rod, a bayonet is inserted inside the mounting hole, locking nuts are connected on both sides of the bayonet, and a copper sheet connecting plate is installed on the top of the insulating rod.

[0005] Furthermore, two groups of insulating rods are distributed on the left and right sides of the top of the tray body, respectively, and the insulating rods are symmetrically distributed about the central axis of the copper sheet connecting piece.

[0006] The locking nuts are symmetrically distributed about the central axis of the bayonet, and the inner diameter of the mounting hole is larger than the outer diameter of the bayonet.

[0007] A guide rod is installed inside the tray body, a movable block is connected to the outer wall of the guide rod, a guide hole is opened inside the movable block, and a guide groove is opened inside the top end of the tray body.

[0008] The guide rods are distributed in two groups inside the tray body, the guide holes are distributed symmetrically about the central axis of the movable block, and the guide grooves are distributed in two groups inside the top of the tray body.

[0009] A connecting column is installed on the top of the movable block, the top of the connecting column is connected to the top of the bottom plate, and two groups of connecting columns are distributed on the top of the movable block.

[0010] The inside of the bottom plate is equipped with mounting columns all around, and the top of the tray body is equipped with connecting holes at the front and rear positions of the guide groove.

[0011] The mounting posts are symmetrically distributed about the central axis of the bottom plate, and the connecting holes are evenly distributed inside the top end of the tray body.

[0012] When the utility model is in use, the connection support between the bottom plate and the connecting column is completed, and the connection installation of the insulating rod is completed by using the base on the top of the bottom plate. At this time, two insulating rods are respectively distributed on the left and right sides of the top of the tray body, and the two insulating rods on the same side are located at the front and rear positions of the same plane. Then, the copper sheet connecting piece can be installed on the two insulating rods on the same side, and the required test lightning arrester is horizontally placed between the interfaces of the copper sheet connecting piece, and the tooling high-voltage line is fixed to one side of the copper sheet connecting piece. Then, it is only necessary to manually connect the low-voltage side. During the test, the high and low voltages of the machine are connected to the copper sheet connecting piece, and then the lightning arrester is placed. In this way, a test current is applied to the lightning arrester through the copper sheet connecting piece to test the lightning arrester. Based on the conductivity of the copper sheet connecting piece, the copper sheet connecting piece on the high-voltage side is fixedly connected to the clip, and it does not need to be held manually, which improves the overall safety.

[0013] When the utility model is in use, the guide rod is installed inside the tray body, the movable block is connected to the outside of the guide rod, and then the connecting column is installed at the top position of the movable block. Therefore, after the insulating rod is connected and installed, the insulating rod can be slid to adjust the spacing between the insulating rods on the left and right sides. At this time, the guide hole will follow the path of the movable block. After adjusting to a suitable spacing, the installation column and the connecting hole can be used to cooperate to complete the connection and installation. Therefore, the overall spacing adjustment ability is better improved during the working process.

[0014] When the utility model is in use, the insulating rod is installed inside the base, and the base and the bottom plate are fixed to each other. When installing the insulating rod, the insulating rod is inserted into the bottom end inside the base, and then the bayonet pin is passed through the installation hole to complete the connection installation between the insulating rod and the base, and finally the bayonet pin is locked and installed with a locking nut, thereby better improving the overall disassembly and installation capability during the working process.

[0015] The beneficial effects of the utility model are: not only the safety is improved, but also the spacing adjustment capability and the disassembly and installation capability of the low-voltage lightning arrester test tooling are improved. BRIEF DESCRIPTION OF THE DRAWINGS
