Electric power test trolley

Abstract

The invention discloses an electric power test trolley which comprises a first supporting plate, a second supporting plate and a third supporting plate, which are sequentially arranged from bottom totop. Lifting assemblies are arranged between the first supporting plate and the second supporting plate and between the second supporting plate and the third supporting plate; main test equipment, a cable roller and a cable roller driving assembly are fixedly arranged on the first supporting plate, wherein the cable roller and the cable roller driving assembly are detachably arranged on one side of the main test equipment; and a controller is fixedly arranged on the third support plate, wherein the controller is electrically connected with the main test equipment and auxiliary test equipment.The electric power test trolley is compact in structure, is high in practicality, can reduce the early-stage preparation work of an electric power maintainer during the onsite withstand voltage detection, and can effectively improve the efficiency of the electric power test; and the electric power test trolley is suitable for an electric power production field, and is used for the field detectionand testing of electric power safety equipment.

Description

technical field [0001] The invention belongs to the technical field of electric power testing, and relates to a device for testing electric power equipment withstanding voltage, in particular to an electric power testing trolley. Background technique [0002] In order to ensure the safety and reliability of the power production site, the "State Grid Corporation of my country Electricity Safety Work Regulations" document clearly stipulates that the power safety equipment such as main transformers, lightning arresters, circuit breakers, SF6 combined electrical appliances, and transformers must be regularly inspected. Conduct field tests and trials. Nowadays, various test instruments and corresponding auxiliary tools are generally transported to the site by a loading vehicle, and then manually removed and installed before the on-site electrical safety equipment can be tested and tested. However, due to the generally large volume and quality of various test instruments, it is ea...

AI Technical Summary

Problems solved by technology

However, due to the generally large volume and quality of various test instruments, it is easy to damage the instrument due to extrusion or bumping during loading and transportation; and it is extremely inconvenient to carry and install the instrument up and down on site. Reduced work efficiency of electrical maintenance personnel

[0003] Of course, there are also trolleys specially used for electric power tests, but the cable rewinding and unwinding on such trolleys are all fixed settings, and when conducting field tests and experiments on electric safety equipment, a certain length of cable is often required to cooperate. The test instrument completes the test work, and the length of the cable is difficult to determine due to the complexity of the test site

Therefore, when the trolley with this structure is used for withstand voltage detection, once the problem of insufficient cable length occurs, the withstand voltage detection will be difficult, which seriously reduces the efficiency of the electric power test.
