Movable multifunctional comprehensive testing platform

Abstract

The invention discloses a movable multifunctional comprehensive testing platform, and relates to the technical field of power detection equipment. The platform includes a hand-pushed four-wheel trolley and an insulation testing platform. The hand-pushed four-wheel trolley includes a vehicle body, a wheel, a handle, an auxiliary tool placement box, a safety warning belt hook, a handle and a grounding bobbin. Lightning arrester placement slots, working-purpose terminals, protection-purpose terminals, discharging bars and discharging bar insulation hooks are disposed on the insulation testing platform. The lightning arrester placement slots include fixing slots, conducting slots and conducting plates. The conducting slots electrically communicate with the outside through the fixing slots. Theconducting plates are disposed at bottoms of the conducting slots. The discharging bars are in clamping connection with the discharging bar insulation hooks. According to the comprehensive testing platform, support for handover testing of three types of equipment of current transformers at and below 35kV, voltage transformers and lightning arresters is realized through technology of the hand-pushed four-wheel trolley, the insulation testing platform, the fixing slots, the conducting slots, the conducting plates and the like, and handover testing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of electric power detection equipment, in particular to a movable multifunctional comprehensive test platform. Background technique [0002] At present, after all kinds of power equipment leave the factory and before they are put into operation, equipment operation and maintenance management units such as power supply companies in various cities are required to conduct corresponding handover tests according to national and industry standards and regulations. After all the test items are passed, they can be installed and delivered for use. At the present stage of my country's rapid industrial and economic development, we are facing severe environmental protection pressure. On the one hand, electricity supports the development of the national economy, and on the other hand, it is necessary to use electricity to achieve sustainable development and alleviate environmental pressure. Replace fuel vehicles with elec...

Problems solved by technology

[0005] Second, there is a lack of an insulating platform for convenient placement of the tested products

The staff usually use "local materials", and sometimes use the tested equipment to pack wooden boxes, non-metallic tables, chairs, benches or discarded equipment, etc. First of all, these materials are not insulating materials in the traditional sense, and their insulating properties have not been professionally tested. The test verification occasionally encounters the phenomenon of ignition and ignition. In addition, the shape of these materials is irregular, and the equipment under test placed on it is not reliable. happens from time to time

[0006] Third, the test of a single test product takes a long time

On the one hand, it takes a certain amount of time to fix the tested product on the insulating material found at hand; on the other hand, it takes a long time to test the wiring. The principle and industry regulations need to short-circuit the two terminals on the primary side of the CT for pressurization, and short-circuit the six terminals 1a-1n, 2a-2n, and da-dn on the secondary side of the CT to ground

The secondary terminals of CT are usually concentrated in a terminal box at the lower part of the equipment. It is very difficult to short-circuit the secondary terminals with a thicker grounding copper wire in the narrow space inside the box, requiring testers to squat or kneel on the ground to operate. It takes as short as three to five minutes and as long as seven or eight minutes to complete the short circuit

Another example is the excitation characteristic test of the voltage transformer hereinafter referred to as "PT". It is necessary to short-circuit three terminals 1n, 2n, and dn in the secondary terminal box to ground, and it is more difficult to short-circuit the ground wire without touching it. For other terminals 1a, 2a, and da that do not need to be grounded, it is time-consuming and laborious to use the thicker grounding copper wire mentioned above to short-circuit not all terminals in a secondary junction box with a small space
