[0002] For insulating operating rods with a withstand voltage rating of 220 kV or above, the whole-rod test method should be used when conducting a withstand voltage test. Usually, the insulating operating rod is subjected to a withstand voltage test by vertical suspension, that is, the operator makes the insulating operating rod vertical and accurately hangs one end of the insulating operating rod on the high-voltage end of the traditional insulating operating rod withstand voltage test platform. However, when the withstand voltage rating of the insulating operating rod reaches 500kV or 1000kV, the axial length of the insulating operating rod will reach more than 6m.

DETAILED DESCRIPTION

[0064] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0065] As described in the background technology, when the withstand voltage level of the insulating operating rod reaches 500kV or 1000kV, the axial length of the insulating operating rod will reach more than 6m. The material of the insulating operating rod is generally a glass fiber reinforced plastic epoxy resin rod, which has a certain toughness. It is difficult to make the insulating operating rod vertical by manpower, and it is difficult to perform a withstand voltage test on the insulating operating rod by vertical suspension. Therefore, how to perform a withstand voltage test on an insulating operating rod with an axial length of more than 6m has become a technical problem that needs to be solved urgently by those skilled in the art.

[0066] To solve the above problems, refer to Figure 1 , Figure 2 , Figure 3 and Figure 4The present invention provides an insulating operating rod withstand voltage test platform, comprising a high-voltage support frame 111, a high-voltage lifting frame 121, a high-voltage clamping assembly 131, a high-voltage introduction assembly 140, a zero-voltage support frame 112, a zero-voltage lifting frame 122, a zero-voltage clamping assembly 132 and a zero-voltage introduction assembly. The axis of the high-voltage support frame 111 is vertically arranged. The high-voltage lifting frame 121 is installed on the high-voltage support frame 111 so as to be movable up and down. The high-voltage clamping assembly 131 is fixedly installed on the high-voltage lifting frame 121 and can move up and down with the high-voltage lifting frame 121. The high-voltage introduction assembly 140 is fixedly installed on the top of the high-voltage support frame 111 and can be connected or disconnected with the high-voltage clamping assembly 131. Installing the high-voltage introduction assembly 140 on the top of the high-voltage support frame 111 can effectively improve the safety of the test. The zero-voltage support frame 112 is arranged in parallel with the high-voltage support frame 111, and the axis is also vertically arranged. The zero-voltage lifting frame 122 is installed on the zero-voltage support frame 112 so as to be movable up and down. The zero-pressure clamping assembly 132 is fixedly mounted on the zero-pressure lifting frame 122 and can move up and down with the zero-pressure lifting frame 122. The zero-pressure introduction assembly is fixedly mounted on the top of the zero-pressure support frame 112 and can be connected or disconnected with the zero-pressure clamping assembly 132. Installing the zero-pressure introduction assembly on the top of the zero-pressure support frame 112 can effectively improve the safety of the test.

[0067] When the insulating operating rod 200 to be tested is subjected to a withstand voltage test, one end of the insulating operating rod 200 to be tested is clamped and fixed by means of the high-voltage clamping assembly 131, and the other end of the insulating operating rod 200 to be tested is clamped and fixed by means of the zero-voltage clamping assembly 132. Afterwards, the high-voltage lifting frame 121 moves upward along the high-voltage support frame 111 to drive the high-voltage clamping assembly 131 to move upward. The zero-voltage lifting frame 122 moves upward along the zero-voltage support frame 112 to drive the zero-voltage clamping assembly 132 to move upward. The high-voltage clamping assembly 131 and the zero-voltage clamping assembly 132 cooperate to drive the insulating operating rod 200 to be tested to move upward. When the high-voltage clamping assembly 131 rises to contact with the high-voltage introduction assembly 140, and the zero-voltage clamping assembly 132 rises to contact with the zero-voltage introduction assembly, the high voltage is input to the high-voltage clamping assembly 131 by the high-voltage introduction assembly 140, so as to input a high voltage to the insulating operating rod 200 to be tested. The zero-voltage clamping assembly 132 is grounded through a cable. Compared with the method of vertical suspension test for withstand voltage, there is no need to use manpower to make the insulating operating rod with an axial length of more than 6m in a vertical state, which reduces the difficulty of the test. At the same time, the operator can install the insulating operating rod 200 to be tested on the insulating operating rod withstand voltage test platform on the ground, and the operator does not need to use a bucket arm truck to lift up to complete the task of hanging and removing the insulating operating rod 200 to be tested, which simplifies the test steps, shortens the test time, saves time and effort, avoids personnel climbing operations, and improves the safety of the test.

[0068] Preferably, the high-voltage support frame 111, the high-voltage lifting frame 121, the zero-voltage support frame 112 and the zero-voltage lifting frame 122 are all square structures, made of insulating materials, specifically glass fiber reinforced plastic epoxy resin. The high-voltage clamping assembly 131, the high-voltage introduction assembly 140, the zero-voltage clamping assembly 132 and the zero-voltage introduction assembly are made of conductive materials, specifically aluminum, iron or steel.

[0069] Specifically, in the example, Figure 1 , Figure 2 and Figure 3 , the high-voltage clamping assembly 131 includes a first high-voltage equalizing ring 1311 and a plurality of high-voltage clamping seats 1312. The first high-voltage equalizing ring 1311 is fixedly mounted on one side of the high-voltage lifting frame 121 close to the zero-voltage lifting frame 122. A plurality of high-voltage clamping seats 1312 are evenly fixed on the first high-voltage equalizing ring 1311 along the circumference of the first high-voltage equalizing ring 1311. Each high-voltage clamping seat 1312 can clamp and fix one end of an insulating operating rod 200 to be tested. It should be noted that when a high voltage is input to the high-voltage clamping assembly 131, the potentials of various parts of the first high-voltage equalizing ring 1311 are equal, so that the potentials of each high-voltage clamping seat 1312 are equal, thereby ensuring that the test conditions of each insulating operating rod 200 to be tested are the same. The zero-voltage clamping assembly 132 includes a zero-voltage equalizing ring 1321 and a plurality of zero-voltage clamping seats 1322. The zero-pressure equalizing ring 1321 is fixedly installed on one side of the zero-pressure lifting frame 122 close to the high-pressure lifting frame 121. A plurality of zero-pressure clamping seats 1322 are evenly fixed on the zero-pressure equalizing ring 1321 along the circumference of the zero-pressure equalizing ring 1321. Each zero-pressure clamping seat 1322 can clamp and fix the other end of an insulating operating rod 200 to be tested. It should be noted that when the zero-pressure clamping assembly 132 is grounded, the electric potentials of various parts of the zero-pressure equalizing ring 1321 are equal, all to 0, so that the electric potentials of each zero-pressure clamping seat 1322 are equal, thereby ensuring that the test conditions of each insulating operating rod 200 to be tested are the same. On the whole, a plurality of insulating operating rods 200 to be tested can be subjected to a withstand voltage test at a single time.

[0070] Preferably, each high-voltage clamping seat 1312 and each zero-voltage clamping seat 1322 is a clamp to facilitate the disassembly and assembly of the insulating operating rod 200 to be tested.

[0071] Specifically, in the example, Figure 1 and Figure 2As shown, the high-voltage introduction component 140 includes a first fixed rod 141, a second high-voltage equalizing ring 142, a high-voltage connection terminal 143 and a high-voltage introduction wire clamp 144. The axis of the first fixed rod 141 is vertically arranged, and the bottom end is fixed to the top of the high-voltage support frame 111. The second high-voltage equalizing ring 142 is installed on the top of the first fixed rod 141. The electric potential of each part of the second high-voltage equalizing ring 142 is equal. The high-voltage connection terminal 143 is installed on the second high-voltage equalizing ring 142 and is suitable for connection with the industrial frequency high-voltage device. The industrial frequency high-voltage device can input high voltage to the high-voltage introduction component 140. The high-voltage introduction wire clamp 144 is fixed to the bottom end of the first fixed rod 141 and is provided with a first accommodating groove with an opening facing downward. A first connecting rod is provided at the top of the first high-voltage equalizing ring 1311 on one side close to the high-voltage lifting frame 121. The first connecting rod is adapted to the first accommodating groove. When the high-voltage clamping assembly 131 moves upward with the high-voltage lifting frame 121, the side wall of the first connecting rod can abut against the first accommodating groove, so that the high-voltage introduction assembly 140 is in contact with the high-voltage clamping assembly 131. When the high-voltage clamping assembly 131 moves downward with the high-voltage lifting frame 121, the side wall of the first connecting rod is separated from the first accommodating groove, so that the high-voltage introduction assembly 140 is disconnected from the high-voltage clamping assembly 131. The zero-voltage introduction assembly includes a second fixed rod, a zero-voltage connection terminal and a zero-voltage introduction wire clamp. The axis of the second fixed rod is vertically arranged, and the bottom end is fixed to the top of the zero-voltage support frame 112. The zero-voltage connection terminal is installed at the top of the second fixed rod and is suitable for grounding. The zero-voltage introduction wire clamp is fixed to the bottom end of the second fixed rod and is provided with a second accommodating groove with an opening facing downward. A second connecting rod is provided at the top of the zero-voltage equalizing ring 1321 close to the zero-voltage lifting frame 122. The second connecting rod is adapted to the second accommodating groove. When the zero-pressure clamping assembly 132 moves upward with the zero-pressure lifting frame 122, the side wall of the second connecting rod can abut against the second containing groove, so that the zero-pressure introduction assembly is in contact with the zero-pressure clamping assembly 132. When the zero-pressure clamping assembly 132 moves downward with the zero-pressure lifting frame 122, the side wall of the second connecting rod is separated from the second containing groove, so that the zero-pressure introduction assembly is disconnected from the high zero-pressure clamping assembly 132.

[0072] Specifically, in the example, Figure 1 , Figure 2 and Figure 3As shown, the insulating operating rod withstand voltage test platform also includes a first lifting mechanism 151 and a second lifting mechanism 152. The first lifting mechanism 151 is installed on the high-voltage support frame 111, connected to the top of the high-voltage lifting frame 121, and used to drive the high-voltage lifting frame 121 to move up and down. The second lifting mechanism 152 is installed on the zero-pressure support frame 112, connected to the top of the zero-pressure lifting frame 122, and used to drive the zero-pressure lifting frame 122 to move up and down. The first lifting mechanism 151 includes two first fixed pulleys 1511, two first lifting belts 1512 and a first rotary driver. The two first fixed pulleys 1511 are rotatably installed on opposite sides of the top of the high-voltage support frame 111. The two first lifting belts 1512 are both vertically arranged. The tops of the two first lifting belts 1512 are connected to the tops of the corresponding sides of the high-voltage lifting frame 121 after passing through the first fixed pulleys 1511 on the corresponding sides. The first rotary driver is arranged below the high-voltage support frame 111, and the output shaft is respectively connected to the bottom end of each first lifting belt 1512, and can reel in and release the two first lifting belts 1512 to drive the high-voltage lifting frame 121 to move up and down. Compared with the form of using a single first lifting belt 1512, the stability of the lifting and lowering of the high-voltage lifting frame 121 is guaranteed. The second lifting mechanism 152 includes two second fixed pulleys 1521, two second lifting belts 1522 and a second rotary driver. The two second fixed pulleys 1521 are rotatably mounted on opposite sides of the top of the zero-pressure support frame 112. The two second lifting belts 1522 are both arranged vertically. The top ends of the two second lifting belts 1522 are connected to the top ends of the corresponding sides of the zero-pressure lifting frame 122 after passing through the second fixed pulleys 1521 on the corresponding sides. The second rotary driver is disposed below the zero-pressure support frame 112, and the output shaft is respectively connected to the bottom end of each second lifting belt 1522, and can reel in and release the two second lifting belts 1522 to drive the zero-pressure lifting frame 122 to move up and down. Compared with the form of using a single second lifting belt 1522, the stability of the lifting of the zero-pressure lifting frame 122 is guaranteed. Overall, the lifting process is smoother, with higher error tolerance, better environmental adaptability, and stronger safety and dexterity.

[0073] Preferably, the first rotary driver and the second rotary driver may be servo motors with higher control accuracy, or may be stepper motors with lower cost.

[0074] Preferably, each first lifting belt 1512 and each second lifting belt 1522 is a nylon rope having high strength and toughness.
