变压器用绕组温控器校验问题分析

Problems analysis of the temperature controls verification for transformer windings

变压器绕组温度控制器的校验,主要目的是判断示值误差、回程误差、设定点误差、切换差等技术指标是否合格。本文针对变压器配套仪表绕组温度控制器校验中出现的问题,进行理论分析,并通过试验论证,得出正确的校验方法。

The aim of the verifying of temperature controls for transformer windings is to judge the technical index whether eligibility such as the indication error, the return error, the contact error and switch error. Aiming at the problems appearing in the verification of temperature controls for transformer windings, makes theoretical analysis, and through test verification, obtains correct verifying methods.
