Abstract

The invention discloses an adjustable support of an electric energy quality evaluation device for electrical specialty, which relates to the technical field of electric energy quality evaluation and comprises a fixing plate, a base, a connecting cylinder and a telescopic rod. According to the structure, the upper portion of a fixing plate is fixedly connected with a base, a connecting cylinder is fixedly installed at the bottom of the fixing plate, a circular cavity is formed in the upper portion of the connecting cylinder, and a circular hole A is formed in one side of the connecting cylinder and is directly communicated with the interior of the cavity; a groove A is formed below the circular hole A, a pin extends into the cavity from the circular hole A, a spring set A is wedged into the groove A until a sliding block A on the spring set A abuts against a limiting block A below the pin, and the spring set A is fixedly connected with the outer wall of the connecting cylinder; and the telescopic rod extends into the cavity from a circular hole B below the connecting cylinder. The support is simple in structure and convenient to use, and detection equipment can be conveniently stored and fixed.

Description

technical field [0001] The invention relates to the technical field of power quality assessment, in particular to an adjustable support for a power quality assessment device for electrical professionals. Background technique [0002] In recent years, the insulation monitoring of the DC power system has been highly valued by the power field, and the importance of the power supply quality of the DC system has gradually been paid attention to, because its power quality will directly affect the safety of the entire system, such as the deterioration of power quality It will lead to a series of production liability accidents. Therefore, it is clearly stipulated in the State Grid Corporation of China Enterprise Standard (Q / GDW1969-2013) "Technical Specifications for Insulation Monitoring Devices for DC System of Substations" that the power quality of the DC power system of substations needs to be tested; Theoretical analysis and engineering summary. [0003] Existing detection equ...
