Description

Electrostatic grounding base plate convenient to install

Technical Field

The utility model relates to a LNG technical field, in particular to static ground connection backing plate convenient to installation.

Background

Grounding is the simplest and most common method for preventing electrostatic disasters, and the types of grounding comprise direct grounding, indirect grounding and bridging grounding, wherein the direct grounding is a grounding type for conductively connecting a metal conductor with the ground so as to enable the potential of the metal conductor to be close to the ground potential; the indirect grounding is a grounding type in which an electrostatic conductor and an electrostatic voltage conductor outside a metal conductor are grounded electrostatically, and the entire or a part of the surface of the conductor is closely connected to the grounded metal conductor, and the metal is used as a grounding electrode; cross-over grounding is a type of grounding in which two or more metal conductors insulated from each other are conductively connected by mechanically and chemically fixing the metal objects to each other to establish a low impedance path for current flow, and then grounded.

Liquefied Natural Gas (LNG), which has methane as a main component and a small amount of ethane and propane, is used as a fuel for power plants, factories, and home users, and also as a raw material for manufacturing chemical industry.
