Embodiment Construction

[0066] The present invention as figure 1 As shown, it is a working method of the grounding pile detector for the lightning protection device of the automobile charging pile, and it works according to the following steps:

[0067] 1) The main power supply module supplies power to generate V2. When the AC input switch is turned on, the DC power supply works and outputs two DC power supplies. One DC output 13.8V / 30A supplies power to electrical equipment. When the power switch K2 is turned on, the DC power supply The output DC voltage V2 starts to supply power to the working power supply module and simultaneously supplies power to the detection module.

[0068] 2) The working power supply module transforms and filters V2 to generate +5V and +3.3V power supplies. After V2 is stepped down by a 7805 three-terminal voltage regulator, it generates +5V power supply. On the one hand, the power supply is used as a DC current sensor module ACS712ELECTR-30A On the other hand, at the same...

Abstract

The present invention relates to the automobile charging field, in particular relates to an working method of an automobile charging pile lightning arrester grounding pile detector which can measure the resistance value change during the whole thunder and lightning occurrence period and is accurate in measurement result. The automobile charging pile lightning arrester grounding pile detector comprises a main power supply module, a working power supply module and a detection module which are connected orderly, the detection module is connected with a lightning protection grounding device, the main power supply module is also connected with the detection module, and the main power supply module and the working power supply module separately supply power to the detection module. The working method of the automobile charging pile lightning arrester grounding pile detector of the present invention can more accurately determine whether the performance of the lightning protection grounding device satisfies the lightning protection requirements of the charging facilities.

Description

technical field [0001] The invention relates to the field of automobile charging, in particular to a working method of a grounding pile detector of a lightning protection device for automobile charging piles. Background technique [0002] With the gradual popularization of new energy vehicles, charging facilities (including charging stations or isolated charging piles) are also spread all over urban communities and parking lots. Although the country or the industry has promulgated relevant technical standards for lightning protection of electrical equipment, such as "GB50057-2016 Design Code for Lightning Protection of Buildings", "GB50303-2015 Code for Acceptance of Construction Quality of Building Electrical Engineering", etc. However, due to cost and other reasons, the safety design of many charging facilities has not reached the standard. In some places with poor conditions, the charging piles are only covered by canopies, and some are even directly exposed. In some plac...
