Problems solved by technology

In order to prevent the electromagnetic waves generated by strong electricity from affecting weak electricity, the distance between weak electricity cassettes and strong electricity cassettes is often required to be more than 20cm, which will also reduce the life of AC relays and AC contactors in the grid-connected inverter.
In addition, the self-generated power of the grid-connected inverter has a great influence on the weak grid, which may easily cause the voltage of the grid to rise

Abstract

The invention relates to a use method of a weak-current grounding device. Multiple weak-current contact pins which are arranged in parallel are configured to perform complete electric contact and communication by automatically adjusting contact positions of the weak-current contact pins when a weak-current contact member is crimped to a corresponding weak-current part of electricity measuring equipment; and a first enclosing part and a second enclosing part moving relative to the first enclosing part are provided, and when the first enclosing part completely covers the weak-current part of the electricity measuring equipment, the second enclosing part is rotated along an axial direction to fix and enclose a shell onto the weak-current part.

Description

technical field [0001] The invention belongs to the technical field of weak current engineering, and in particular relates to a method for using a weak current grounding device. Background technique [0002] In the prior art, the light-current cassette and the strong-current cassette used in integrated wiring engineering both adopt the same plastic structure. In order to prevent the electromagnetic waves generated by strong electricity from affecting weak electricity, the distance between weak electricity cassettes and strong electricity cassettes is often required to be more than 20cm, which will also reduce the life of AC relays and AC contactors in the grid-connected inverter. In addition, the self-generated power of the grid-connected inverter has a great influence on the weak grid, which may easily cause the voltage of the grid to rise. Contents of the invention [0003] In order to solve the above technical problems, the technical solution adopted by the present inv...
