Description

Technical field

The invention relates to the technical field of test and detection of electric power safety

tools and instruments, in particular to a folding 110kV hot stick & electroscope combined

test supporting frame and a test box. Background technique

For safety tools such as hot stick and electroscope, power frequency AC voltage

withstand test is required regularly. Container type mobile test platform for safety tools and

instruments is the first choice to deal with multiple tests efficiently at present.

In the container type safety tools and instruments mobile detection platform, the

complete set of safety tools and instruments test equipment are installed and stored in the

test box, which can complete the test in different regions. The container can be carried by

medium-sized trucks, and all equipment shall be reasonably arranged in the container. The

box itself is separated from the driving space and equipment area to fully ensure the safety

of drivers and passengers. Control cabinet and equipment placement cabinet are set inside

the box. The instruments and equipment shall be reasonably arranged, stably fixed, and form

a test system with portable computer mobile station. Some equipment can be disassembled

and moved, and can be separated from the system. It can be used as an independent

instrument for temporary site test. Each instrument can adopt patented technology of

multichannel high-pressure leakage measurement, infrared data communication technology

and computer wireless control technology to realize the purpose of safely measuring high

voltage leakage current. By completely isolating the tester from the high voltage system and

the computer from the test system, it can not only accurately measure the multichannel high

voltage leakage current, but also ensure the personal safety of the tester.

The standard hot stick test supporting frame and electroscope test supporting frame can

electrically adjust the electrode distance both remotely and locally, moreover, a scale to

measure the segment length is provided. However, as the hot stick supporting frame and

electroscope support generally occupy a large volume, it is difficult to be equipped in the

box simultaneously Summary

The technical problem to be solved by this invention is that the existing container type

safety tools and instruments mobile detection platform is difficult to equip them in the box at the same time because the container volume is limited and the occupied volume of hot stick supporting frame and electroscope support is generally large .The purpose of the invention is to provide a folding 110kV hot stick & electroscope combined test supporting frame and test box, and each support is designed into a folding test equipment, which can greatly reduce the floor area, reduce the occupied space of the equipment and meet the requirements of mobile test. The invention is realized through the following technical scheme: The invention relates to a folding 110kV hot stick & electroscope combined test supporting frame, which comprises a hot stick test supporting frame and an electroscope test supporting frame. The invention is characterized in that it also includes a sliding structure, and the hot stick test supporting frame and the electroscope test supporting frame are connected together through their common sliding structure. The sliding structure comprises a first base, a second base and a sliding base. The ball screw between the first base and the second base passes through the sliding base and the sliding base can slide along it. The second base and the sliding base are used to cooperate with the installation of the hot stick test supporting frame. The first base is used for installing the electroscope test supporting frame. The first hot stick supporting frame is vertically installed on the sliding base. And a space for accommodating the height of the first hot stick supporting frame is provided between the first base and the second base. A second hot stick supporting frame is vertically installed on the second base. When the sliding base is at one end of the first base, the first hot stick supporting frame canbe folded along the direction of the ball screw, and the second hot stick supporting frame can also be folded along the direction of the ball screw. The working principle is: the existing standard container type safety tools and equipment mobile detection platform equipment configuration, due to its limited internal space, each test equipment needs to reduce the volume as much as possible to facilitate container loading under the condition of meeting the normal test requirements. Among the pressure test equipment required for the test, the special test equipment for each test object shall be used for the test of different types of safety tools and instruments. For example, when it is necessary to test different types of capacitive type electroscope below 35KV or

63kV ~ 100kV separately, prepare spherical electrodes and ring electrodes of various

specifications respectively, then adjust the spacing between the two poles according to the

length of the electroscope test object, and then install the electrodes on the fixed base to

forma special test equipment. In order to meet the test requirements, additional equipment

stations should be added to deal with it, and considering the experimental safety insulation

distance, the requirements will be extremely harsh for the container platform with limited

volume. The hot stick test needs to ensure the fixed electrodes at both ends with the same

length as the rod body to ensure the measurement length, which also needs a large occupied

space. Although these equipment can complete the normal test, they cannot be folded and

transported, so they are not suitable for container platform. When a number of equipment

need to be moved, the man hours of personnel are increased, and it cannot meet the

requirements of portable assembly on container.

Therefore, the invention provides a folding 110kV hot stick & electroscope combined

test supporting frame. By assembling the hot stick test supporting frame and the

electroscope test supporting frame by sharing a sliding base, the equipment structure can be

adjusted immediately as needed, so as to carry out the power frequency voltage withstand

test for different types of hot sticks and electroscope, so as to achieve multi functionality,

space saving and efficiency. When it needs to be loaded into the box, the whole can be

folded by adjusting the movable hinge on the base, so as to further reduce the floor area,

make the movement easier, and perfectly solve the problem of limited loading space of

container type safety tools and instruments mobile detection platform.

Preferably, the opposite sides of the second base and the sliding base are provided with

movable hinges, through which the first hot stick supporting frame is folded along the

direction of the ball screw, and the second hot stick supporting frame is folded along the

direction of the ball screw. The folding and storage of the first hot stick supporting frame

and the second hot stick supporting frame are realized through the cooperation of two

movable hinges.

Preferably, it also includes a scale slide rail, which is arranged between the first base

and the second base and is arranged in parallel with the ball screw. The scale slide rail

penetrates the sliding base.

The scale slide rail is uniformly provided with a scale for adjusting the spacing offixed

electrodes to achieve accurate adjustment.

second support column. The first support column comprises two vertical and parallel support

rods, and the first support column is provided with a second support column through a

connector. It is considered that the top of the second support column is used to install the

electroscope test object to prevent it from being broken down by electric shock in the

process of electrical inspection. The second support column is a support column made of

insulating material.

Preferably, it also includes two stay wires. One end of the two stay wires is arranged on

the connecting piece, and the other end is respectively arranged on both sides of the

electroscope base to maintain stability.

Preferably, the ring electrode to be tested is installed on the first base through the

support frame, and the first hot stick supporting frame is installed with the ball electrode to

be tested through the support rod. The ring electrode to be tested and the ball electrode to be

electrode and ring electrode of different specifications.

Preferably, the ring electrode to be tested and the ball electrode to be tested cooperate to

measure the capacitive type electroscope between 35kV and below and 63kV-100kV.

Preferably, an insulator is arranged on the second hot stick supporting frame.

On the other hand, the invention also provides a test box, which is provided with a

supporting frame for test, and the supporting frame for test is a folding 110kV hot stick &

electroscope combined test supporting frame. When the combined supporting frame for test

needs to be loaded into the test box, it can be folded for storage, so as to reduce the floor

area and make the movement easier. When the combined supporting frame for test is used,

the hot stick test supporting frame and the electroscope test supporting frame share a sliding

base, which can be assembled and used conveniently and quickly.

Detailed description

In order to make the purpose, technical scheme and advantages of the invention clearer,

the invention is further described in detail below in combination with the embodiments and

attached drawings. The schematic embodiment and description of the invention are only

used to explain the invention and are not used as alimitation of the invention.

Example 1

As shown in Figures 1 to 5, the invention relates to a folding 110kV hot stick

& electroscope combined test supporting frame, which comprises a hot stick test supporting

frame and an electroscope test supporting frame. The invention is characterized in that it

also includes a sliding structure, and the hot stick test supporting frame and the electroscope

test supporting frame are connected together through their common sliding structure. The

sliding structure comprises a first base 1, a second base 2 and a sliding base 3. The ball

screw 12 between the first base 1 and the second base 2. The ball screw 12 passes through

the sliding base 3 and the sliding base 3 can slide along it. The second base 2 and the sliding

base 3 are used to cooperate with the installation of the hot stick test supporting frame, and

the first base 1 is used to install the electroscope test supporting frame.

A first hot stick supporting frame 5 is vertically installed on the sliding base 3, a space

for accommodating the height of the first hot stick supporting frame 5 is provided between

the first base 1 and the second base 2, and a second hot stick supporting frame 6 is vertically

installed on the second base 2.When the sliding base 3 is at one end of the first base 1, the

first hot stick supporting frame 5 can be folded along the direction of the ball screw 12, and

the second hot stick supporting frame 6 can also be folded along the direction of the ball

screw 12.

In this embodiment, due to the limited loading space inside the container, it will be

difficult to load the electroscope supporting frame for test and hot stick test supporting frame

at the same time during transportation. For the designed hot stick electroscope combined test

folding support, a movable hinge 7 is arranged on the opposite sides of the second base 2

and the sliding base 3. Through the inward folding movable hinge, the first hot stick supporting frame 5 and the second hot stick supporting frame 6 can be changed from a vertical state to a parallel state with the sliding rail, so as to liberate the upper space. The electroscope support part can also be separated from the upper and lower support columns at the same time and stored separately. Universal pulleys are respectively installed at the four comers of the base to make the movement more convenient and fast. After the test platform is deployed, the placement position can be adjusted at any time according to the test requirements.

The invention provides a folding 110kV hot stick & electroscope combined test

supporting frame, which can be assembled by sharing a sliding base between the hot stick

test supporting frame and the electroscope test supporting frame, and the equipment

structure can be adjusted immediately as needed, so as to carry out the power frequency

voltage withstand test of different types and models of hot sticks and electroscope, so as to

multi functionality, space saving and efficiency. When it needs to be loaded into the box, the

whole can be folded by adjusting the movable hinge on the base, so as to further reduce the

floor area, make the movement easier, and perfectly solve the problem of limited loading

space of container type safety tools and instruments mobile detection platform.

Example 2

As shown in Figures 1 to 5, the difference between this embodiment and embodiment 1

is that this embodiment also includes a scale slide 4, which is arranged between the first base

1 and the second base 2 and is arranged parallel to the ball screw 12. The scale slide rail 4

penetrates the sliding base 3.

The scale slide rail 4 is uniformly provided with a scale for adjusting the spacing of

fixed electrodes to achieve accurate adjustment.

In this embodiment, the electroscope test supporting frame comprises an electroscope

base 8, and the electroscope test article 13 is installed on the electroscope base 8 through an

electroscope support column.

In this embodiment, the electroscope support column includes a first support column 9

and a second support column 10, the first support column 9 includes two vertical and

parallel support rods, and the first support column 9 is provided with a second support

column 10 through a connector. It is considered that the top of the second support column 10 is used to install the electroscope test object 13 to prevent it from being broken down by electric shock in the process of electrical inspection. The second support column 10 is a support column made of insulating material. In this embodiment, it also includes two stay wires 11. One end ofthe two stay wires 11 is arranged onthe connecting piece, and the other end is respectively arranged on both sides of the electroscope base 8 to maintain stability. In this embodiment, the ring electrode 14 to be tested is installed on the first base 1 through the support frame, and the first hot stick supporting frame 5 is installed with the ball electrode 15 to be tested through the support rod. The ring electrode 14 to be tested and the ball electrode 15 to be tested can be disassembled and replaced freely, which is convenient to replace spherical electrodes and ring electrodes of different specifications. In this embodiment, the ring electrode 14 to be tested and the ball electrode 15 to be tested cooperate to measure the capacitive type electroscope of 35kV and below and the capacitive type electroscope of 63kv-I00kv. In this embodiment, an insulator is arranged on the second hot stick supporting frame 6.

The container type safety tools and instruments mobile detection platform of the invention is a new type of mobile detection equipment. The device needs to detect all common safety tools and instruments, so it needs to be equipped with a variety of detection equipment. Due to the limited volume of containers and large space occupied by various independent equipment, it is difficult to provide complete test equipment. Therefore, it is

necessary to develop multifunctional folding test equipment to reduce the occupied space of equipment and meet the requirements of mobile test. Considering that the 110kV voltage level usually includes an hot stick test supporting frame, a 10-35kV electroscope supporting frame for test and a 63-110kv electroscope supporting frame for test, the multi equipment integrated structural design of the invention extends the electric hot stick test supporting

frame and the electroscope supporting frame for test upward based on the same sliding base. The ring electrode 14 of the invention can be disassembled and replaced freely. The electrode ends of different voltage levels can be selected according to the test situation, so that the electroscope test part can meet the electroscope test requirements of various specifications. The rotatable ball electrode 15 support can also meet the electroscope test of two different voltage levels. The sliding base can freely adjust the spacing between the ball electrode 15 and the electroscope test object 13. It is matched with the electroscope fixed base which can be disassembled and assembled freely to form a complete set of electroscopes supporting frame for test.

When carrying out the withstand voltage test of the hot stick, the invention takes the

electrode end supported and fixed by the insulator as the base point, and can adjust and slide

the fixed end of the other electrode according to the scale on the slide rail, so as to ensure

the distance between the two electric poles and meet the erection and test of hot sticks with

different lengths of each voltage grade.

(1) When the 10-35kV electroscope supporting frame for test is used for testing, the

grounding electrode is a ring electrode structure. Remove the removable grading ring and

replace it with a small grading ring consistent with its test voltage level. The high voltage

electrode is a spherical electrode. Rotate the support rod of the spherical electrode 15 by 180

degrees, and use the small spherical electrode 15 as the high voltage end. The bottom sliding

base can adopt two control modes of key and wireless remote control to ensure that the

voltage equalizing ring surrounds the ball electrode 15 to form a uniform electric field, fix

the electroscope to be tested on the top of the electroscope support, and align the measuring

point of electroscope test article 13 with the ball electrode 15.

(2) During the 63-110kV electroscope test, also remove the small grading ring and

replace the large grading ring, rotate the support of the ball electrode 15 for 180 degrees, use

the large ball electrode with higher voltage level at the other end to form a grading field with

the ring electrode 14, fix the electroscope test article 13 and align it with the high voltage

ball electrode.

(3) During the withstand voltage test of the hot stick, the fixed electrode spacing can be

adjusted according to the length of the hot stick of the test object and the scale on the slide

rail. The motor adopts two control modes: key press or wireless remote control. At the same

time, adjust the telescopic support height to make the fixed electrodes at both ends parallel,

and then set up the hot stick to start the test.

Example 3

As shown in Figures 1 to 5, the difference between this embodiment and embodiment 1 is that this embodiment also provides a test box, which is provided with a supporting frame for test, and the supporting frame for test is a folding 110kV hot stick & electroscope combined test supporting frame. When the combined supporting frame for test needs to be loaded into the test box, it can be folded for storage, so as to reduce the floor area and make the movement easier. When the combined supporting frame for test is used, the hot stick test supporting frame and the electroscope test supporting frame share a sliding base, which can be assembled and used conveniently and quickly. In this invention, a test box is designed to meet the increasing test demand of safety tools. In order to realize the batch inspection test, the inspection platform led by the movable container test platform is more and more widely used. However, due to the limitation of the box loading capacity, many test equipment are too large to be equipped for the test vehicle at the same time. This test box has a new integrated design for the hot stick test and electroscope supporting frame for test, which accounts for the largest proportion in the test. It integrates the functions of the three equipment, which greatly solves the problem of limited storage space of the container test platform.
