Description

Technical Field

[0001] The utility model belongs to the technical field of power facility testing, and in particular relates to an adjustable power facility testing workbench. Background Art

[0002] The power facility test bench is a professional equipment or platform designed for various tests, verifications and calibrations of power facilities such as high and low voltage switchgear, transformers, circuit breakers, relays, etc. It provides a workplace that simulates the actual power system environment so that comprehensive performance evaluation and fault detection can be carried out before the equipment is officially put into operation. The power facility test bench plays an important role in the construction, maintenance, upgrade and transformation of the power system. Through testing, it can be ensured that the power facilities meet the design requirements before being put into operation, and have good performance and reliability, thereby reducing the failure rate and improving the overall operation efficiency of the power system. At the same time, the test bench can also be used for fault diagnosis and maintenance of power facilities, helping technicians to quickly locate problems and improve maintenance efficiency.

[0003] Publication No. "CN218776545U" discloses a workbench. The workbench includes a bearing platform and a bearing frame, the bearing frame includes a placement piece, the placement piece is used to place a light source to be tested, the placement piece is slidably connected to the bearing platform to drive the light source to be tested to move along a first direction, and the placement piece and the integrating sphere are arranged along the first direction. According to the workbench of the present application, in the cold light source performance test, the operation steps are simplified, and the test is more convenient.

[0004] Although the above-mentioned utility model simplifies the operating steps and makes testing more convenient in the cold light source performance test, the casters at the bottom of the workbench cannot be retracted and extended. When testing power facilities, the stability of the workbench is maintained solely by the friction between the casters and the ground. When facing external force impact or vibration, the workbench is prone to sliding or displacement, resulting in reduced test accuracy or equipment damage. In addition, changes in ground conditions such as humidity and unevenness will also affect the stability of the friction, further reducing the stability of the workbench. Different ground conditions such as material, flatness, cleanliness, etc. will affect the friction between the casters and the ground, thereby affecting the stability of the workbench.
