Baoding dry type transformer is widely used in local lighting, high-rise buildings, airports, ports, CNC mechanical equipment and other places. Simply put, baoding dry type transformer refers to the transformer whose iron core and winding are not impregnated in insulation oil. In the power system, the general steam transformer, boiler transformer, dust removal transformer, dust removal transformer, desulfurization transformer are baoding dry transformer, the ratio of 6000V/400V and 10KV/400V, used with rated voltage 380V load. Simply said baoding dry type transformer refers to the core and winding are not impregnated in the insulation oil of the transformer. Large capacity: from 50 ~ 2500 kva distribution transformer baoding dry type transformer, to expand of 10000 ~ 20000 kva / 35 kv power transformer, as the city power load increasing, the city of substation network area is more and more into the city, residential quarters, large load centers such as factories and mines, 35 kv large area power supply power transformer center will receive a wide range of applications.

Then, baoding dry transformer protection system has the following:

1. Gas protection.
Gas protection refers to the internal short-circuit (including turn-to-turn short-circuit) of baoding dry transformer, but when the short-circuit current cannot reach the fixed value of current protection, the protected transformer will trip directly. It belongs to the main protection of baoding dry type transformer, which cannot be removed in normal operation. According to the operating pressure of gas relay, the transformer can be divided into two kinds of conditions: the heavy gas can be operated at tripping, the light gas can be operated at tripping, and the light gas can be operated at signal.

2. Temperature protection.
Baoding dry transformer is generally set with two levels of temperature protection: low temperature alarm, high temperature tripping, the specific temperature value can be set according to the transformer manufacturer's instructions.
