Description

Technical Field

[0001] This invention relates to the field of relay protection device testing equipment technology, and in particular to a reliability testing platform suitable for relay protection devices. Background Technology

[0002] Relay protection devices typically require reliability testing during production. This involves testing the reliability and strength of the wires after connection, which necessitates the use of a reliability testing platform.

[0003] When using the existing testing platform, the relay protection device is poorly fixed, and it is easy to cause the relay protection device to move along with it. It lacks an auxiliary limiting structure. After the wire detaches during the test, it is easy to cause impact. It also lacks an auxiliary buffer structure. Furthermore, when the wire is pulled, there is no structure that allows for easy switching between manual and electric drive. At the same time, when pulling the wire, it is easy to slip, and there is no structure to improve the fixed connection. Summary of the Invention

[0004] The purpose of this invention is to provide a reliability testing platform suitable for relay protection devices, so as to solve the technical problems of poor fixing effect, lack of buffer structure and lack of electric drive in relay protection devices.

[0005] To achieve the above objectives, the present invention provides a reliability testing platform suitable for relay protection devices, which includes a testing platform body, wherein a fixing component, a guide component, and a moving component are sequentially installed on the upper surface of the testing platform body from front to back;

[0006] The fastener includes a support block and a top piece. The support block has a limiting groove and a positioning groove. The limiting groove is connected to the positioning groove. The limiting groove is located at the rear end of the support block, and the positioning groove is located at the front end of the support block. The top piece is placed on the top of the support block.

[0007] The bottom of the movable component is provided with a sliding groove, and the top of the sliding groove is provided with a sliding rod. An electronic tension gauge is installed on the top of the movable component. A traction plate is provided at the front end of the electronic tension gauge. A pressure block is provided at the top of the traction plate. An arc-shaped groove is provided at the bottom of the pressure block. Several fixing heads are provided on the inner surface of the arc-shaped groove. The fixing heads are used to fix the wires of the relay protection device.

[0008] The front end of the guide is provided with a control groove that is slidably connected to the sliding rod, and the rear end of the guide is provided with an installation component. The installation component is fixedly connected to the test platform body, and a driving component is installed on the installation component. The left and right sides of the installation component are respectively provided with elastic side plates. When the moving component moves towards the front end of the guide, the moving component abuts against the side plates of the guide.

[0009] Preferably, the fastener includes an elastic inner plate disposed inside the positioning groove.

[0010] Preferably, the support block is provided with guide grooves on its left and right sides, and the bottom of the top member is provided with guide members on its left and right sides. The guide members are embedded in the guide grooves and control the movement of the top member.

[0011] Preferably, the support block has circular holes on its left and right sides, the guide member has a guide rod inserted into the circular hole of the support block, and a spring is sleeved on the outer periphery of the guide rod.

[0012] Preferably, the movable component has elastic side members on its left and right sides, and the side plates are provided with contact heads. When the movable component moves toward the front end of the guide, the side members abut against the contact heads.

[0016] This invention provides a reliability testing platform for relay protection devices. Compared with existing technologies, its advantages are as follows: During use, the relay protection device is first manually connected to the wire. Pulling the top component upwards places the relay protection device into the positioning groove, embedding the wire into the limiting groove. Then, the top component is released, preventing the relay protection device from rising and thus improving its fixation. Pulling the pressure block upwards embeds the wire into the arc-shaped groove of the pressure block, fixing the fixing head to the wire and improving the fixation, preventing slippage during pulling. Then, the control switch of the electronic tension gauge is turned on, and the gauge is pulled to stretch the wire until it detaches from the relay protection device. When they detach, the electronic tension gauge automatically records the tension value, quickly testing the fixation reliability of the relay protection device. After the wire displacement, when the moving component moves towards the front end of the guide, it abuts against the side plate of the guide, and the side plate utilizes its elasticity to improve the buffering effect. When the wire cannot be manually pulled off, the driving component is controlled to move the moving component, thereby improving the testing reliability of the device. The testing platform of this invention effectively solves the technical problems of poor fixation, lack of buffer structure, and lack of electric drive in reliability testing of relay protection devices.

[0031] like Figures 1-8As shown, the present invention provides a reliability testing platform suitable for relay protection devices, comprising a test platform body 100. A fixing component 1, a guide component 2, and a moving component 3 are sequentially mounted on the upper surface of the test platform body 100 from front to back. The fixing component 1 includes a support block 101 and a top component 106. The support block 101 has a limiting groove 102 and a positioning groove 103, which communicate with each other. The limiting groove 102 is located at the rear end of the support block 101, and the positioning groove 103 is located at the front end of the support block 101. The top component 106 covers the top of the support block 101. The bottom of the moving component 3 has a sliding groove 301, and a sliding rod 302 is provided at the top of the sliding groove 301. An electronic tensioning device is installed at the top of the moving component 3. The electronic force gauge 300 has a traction plate 306 at its front end, a pressure block 307 at the top of the traction plate 306, an arc-shaped groove at the bottom of the pressure block 307, and a plurality of fixing heads 308 on the inner surface of the arc-shaped groove for fixing the wires of the relay protection device. The guide 2 has a control groove 201 at its front end that is slidably connected to the sliding rod 302, and an installation part 202 at its rear end. The installation part 202 is fixedly connected to the test platform body 100. A driving part 208 is installed on the installation part 202.

Pull the pressure block 307 upward to embed the wire into the arc-shaped groove of the pressure block 307, so that the fixing head 308 is fixedly connected to the wire, improving the fixing effect and preventing slippage when pulling. Then turn on the control switch of the electronic tension gauge 300 to make the electronic tension gauge run, and then pull the electronic tension gauge 300 to make the wire be pulled until the wire is separated from the relay protection device. When the two are separated, the electronic tension gauge 300 automatically records its tension value, thereby quickly testing the fixing reliability of the relay protection device. After the wire is displaced, when the moving part 3 moves towards the front end of the guide 2, the moving part 3 abuts against the side plate 203 of the guide 2, and the side plate 203 utilizes its elasticity to improve the buffering effect. When the wire cannot be pulled off manually, the driving part 208 is controlled to drive the moving part 3 to move, thereby effectively improving the test reliability of this device. In summary, the test platform of this invention effectively solves the technical problems of poor fixing effect, lack of buffering structure, and lack of electric drive in the reliability testing of relay protection devices.
