Microprocessor Silicon Steel Transformer Core Cold Rolled

Microprocessor silicon steel transformer lamination cores core Made In China Low Price

The iron core multi-point ground fault judgment method is usually detected from two aspects:
(1) Perform gas chromatography analysis. In the chromatographic analysis, if the content of methane and olefin components in the gas is high, and the content of carbon monoxide and carbon dioxide gas does not change much from the past, or the content is normal, it means that the core is overheated. To.
When acetylene gas appears in the chromatographic analysis, it indicates that the iron core has intermittent multi-point grounding.
(2) Measure the current of the ground wire. You can use a clamp meter to measure whether there is current on the ground lead of the grounding sleeve outside the transformer core. When the transformer core is normally grounded, it is formed due to no current loop. The current on the ground wire is very small, which is milliampere level (generally less than 0.3A). When there are multiple points of grounding, there is a short circuit turn around the core's main magnetic flux, and the circulating current flows through the turn. Its value depends on the relative position of the fault point and the normal ground point, that is, how much magnetic flux is surrounded by the short circuit turns. Generally up to tens of amps. By measuring the presence or absence of current in the ground lead, it can be accurately judged whether the iron core has a multi-point ground fault.

Jiangyin hengtong was found in 1989.it is a large scale , standardization, consideration, and information all constitute important factors in the development of steel managing enterprises. The company located in jiangyin city-the NO.1 of the TOP 100 cities in China ,faces the shanghai on the east and near the changjiang river on the north ,with the ascendant geographical location and convenient transportation makes goods reach to destination very quickly.
