Embodiment Construction

[0045] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0046] In one embodiment, such as figure 1 As shown, a voltage sag immune time detection method is provided, comprising the following steps:

[0047] Step 110, analyze the circuit, and acquire sensitive equipment in the circuit.

[0048] Specifically, a sensitive device is a device that produces a withstand characteristic when a voltage sag occurs. That is, sensitive equipment will have tolerance characteristics when the voltage sags. This sensitive device has a certain tolerance. Different sensitive devices have different tolerances.

[0049] In this step, the circui...

Abstract

The present application relates to a method for detecting immunity time of voltage sag, including: analyzing the circuit, obtaining sensitive equipment in the circuit; acquiring the immunity time of each sensitive equipment; acquiring the immunity time of each sensitive equipment according to the immunity time of each sensitive equipment. Immunity time of the circuit. In this application, the immune time of the sensitive process of the circuit is obtained based on the immune time of the sensitive equipment, so as to effectively detect the power supply reliability of the circuit.

Description

technical field [0001] The present application relates to the technical field of power supply testing, in particular to a voltage sag immune time detection method. Background technique [0002] With the overall improvement of social productivity, basic issues such as power supply reliability have reached a higher level, and the increasing demand for power supply quality in the highly automated production process that ensures efficient production has become a major contradiction that power companies need to deal with in the new era. The voltage sag is the biggest contributor to all kinds of power quality problems that cause economic losses to users. The first step to improve voltage quality is to know the voltage sag withstand capability of typical sensitive equipment or processes through testing and certain evaluation methods. [0003] At this stage, there have been certain research results in the testing of sensitive equipment. The Ouyang Sen team of South China Universit...
