In addition, since the tools and accessories used are relatively concentrated, they are not easy to drop after use.

Description

Mobile high voltage test operation platform

technical field

The utility model relates to a device for carrying and transporting test equipment such as instruments and meters in the high-voltage test process of power transformation equipment, which belongs to the testing technical field.

Background technique

During the condition-based maintenance of substation equipment, it is often necessary to conduct routine tests and live tests on multiple high-voltage electrical equipment in different locations. At present, the test equipment, instruments and other tools are generally carried by the test personnel by hand and arranged temporarily. Due to the large number of test sites and scattered electrical equipment, some instruments are relatively heavy, and frequent handling greatly increases the labor intensity of the test personnel. In addition, due to the many test items of electrical equipment, there are many test equipment, instruments, various accessories, tools, and test lines that need to be used, resulting in complicated on-site operations, confusing wiring, long test preparation time, low work efficiency and various Accessories, tools, and test leads are also easy to lose.

Utility model content

The purpose of the utility model is to overcome the deficiencies of the prior art and provide a mobile high-voltage test operation platform to reduce the labor intensity of test personnel and improve test efficiency.

Problem described in the utility model is realized with following technical scheme:

A mobile high-voltage test operation platform, which includes a walking trolley, on which a test power supply box and an instrument box are sequentially placed, the test power supply box is provided with a side cover, and an accessory box, a power supply Spool, power socket and protection device.

In the mobile high-pressure test operation platform, two wheels are respectively arranged at the front and rear of the trolley, the two wheels at the front are universal wheels, and the two wheels at the rear are directional wheels.

In the above-mentioned mobile high-voltage test operation platform, the four corners of the bottom surface of the instrument box are provided with downward docking plugs, and the four corners of the top surface of the power box are provided with docking grooves matching the docking plugs of the test instrument box.

In the above-mentioned mobile high-voltage test operation platform, the instrument box is provided with two layers, and the upper instrument box and the lower instrument box are also connected by a docking plug and a docking groove.

The utility model uses a walking trolley to transport test equipment, instruments, tools and accessories, and places the test equipment and instruments in the instrument box for testing. It is not necessary to move up and down during the test, which greatly reduces the labor intensity of the test personnel. The tools and accessories are placed in the power box, which is very convenient to access and effectively improves the test efficiency. In addition, because the tools and accessories used are relatively concentrated, they are not easy to drop after use.

Detailed ways

Referring to Figures 1 to 3, the utility model includes a walking trolley 1, a test power supply box 2 and an instrument box, wherein the instrument box is divided into a lower instrument box 4 and an upper instrument box 5; the test power supply box 2 is provided with a test accessory box 10. Power spool 2, power socket and protection device 6.

When the utility model is used, according to the operation content at that time, all the test instruments, tools, test leads, etc. required for routine tests such as high-voltage circuit breakers, current transformers, coupling capacitors, and voltage transformers can be placed in the test operation. On the platform, all the test instruments during the test can be placed on the operation platform without having to be moved up and down, which greatly saves the preparation time before on-site work.

There are many accessories, tools and test lines used in the circuit breaker test, which are easy to lose. The utility model specially designs the circuit breaker test accessory box 10, which effectively avoids the loss of accessories.

When the work site is transferred, the greatest advantage of the utility model can be brought into play: only one person is required to push and the transfer of all test instruments, meters and tools can be easily completed.

The mobile operating platform has four wheels, the front two are universal wheels 8, and the rear two are directional wheels 7, which ensure that the walking trolley turns flexibly. For the convenience of on-site use, the loading part of the mobile operating platform is divided into three layers, the lowest layer is the test power supply box 3, which contains the power supply spool 2, power socket and protection device 6 and accessory box 10. The middle layer and the top layer are instrument boxes, and the adjacent two layers of boxes are connected by docking plugs 11 and docking grooves 13, so the disassembly and installation are very flexible. The frame of each part of the mobile operating platform is made of stainless steel with high mechanical strength and good electrical conductivity, and special grounding bolts are installed on the conductive shell. The utility model effectively solves the problem that it is difficult for high-voltage test personnel to carry test instruments on site. The results of several trials show that compared with the previous staff who carried the test equipment by hand, the utility model can save the physical strength of the staff, reduce labor intensity, save time, improve work efficiency, and avoid the loss of test tools and test accessories. It is suitable for the power failure test of the main transformer unit of the substation or the routine test with a relatively large power failure range.
