Some protection of dry type transformer:
1. Gas protection.
Gas protection is a kind of protection that directly trips the protected transformer when the short-circuit current cannot reach the setting value of current protection when the internal short-circuit (including inter turn short-circuit) occurs in dry-type transformer. It belongs to the main protection of dry-type transformer and cannot be removed in normal operation. According to the action pressure of gas relay, the transformer is divided into two situations: heavy gas acts on tripping, light gas acts on tripping and light gas acts on signal.
2. Temperature protection.
Dry type transformer is generally set with two levels of temperature protection: low temperature alarm and high temperature trip. The specific temperature value can be set according to the instructions of the transformer manufacturer
Extension of knowledge points:
Dry type transformer refers to the transformer whose core and winding are not immersed in insulating oil. Dry type transformer is widely used in local lighting, high-rise buildings, airports, docks, CNC machinery equipment and other places. The company produces S11, S13 series oil immersed transformer, scb10, scb11, scb12 series dry-type transformer, sbh15 amorphous alloy transformer, ks11 / ks13 mining transformer, kbsgzy mining flameproof transformer, oil field transformer, plateau transformer, coal mine transformer, furnace transformer, and on load voltage regulating power transformer and other low loss power transformers The company strictly implements the technical standards such as GB 1094.1, 2-2013 and GB / t6451-2015, and takes the lead in obtaining ISO9001 quality management system certification certificate and PCCC energy-saving product certification certificate among peers, and the leading products reach the leading level in the same industry.
