Xiamen Qihe Electric Co., Ltd. on the national network blacklist due to quality issues

In order to promote the integrity of Xiamen Qihe Electric Co., Ltd., to ensure product quality, to ensure the smooth construction of the power grid and safe and reliable power supply, in accordance with the relevant provisions of the "State Grid Corporation Supplier Bad Behavior Management Regulations", the issue of Xiamen Qihe Electric The company has handled it. The specific processing situation is as follows:


Full name of the supplier: Xiamen Qihe Electric Co., Ltd.

Description of bad behavior: 1. The value of the FTU dial does not match the mark. When the dial code is 88, 89, 98, 99, the zero sequence current and the delay setting check are unqualified. 2. The on-column circuit breaker delivery inspection model does not match the in-plant sampling inspection model. The specific situation of the China Electric Power Research Institute High Voltage Research Institute is as follows: “In the process of performing the -0.3s combined operation sequence, in the first 20ms after 20kA disconnection, three-phase heavy breakdown occurred, three-phase power frequency current appeared, and the test failed. 3. The partial discharge of the voltage transformer exceeded the standard and the appearance was damaged.

Treatment measures: Suspended the bidding qualification in the FTU and the on-column circuit breaker package for 2 months.

Processing range: FTU, on-column circuit breaker

SMD Transformer

SMD transformer Description: small size, high working frequency, high adhesion performance, small distribution inductance;It is mainly used for module power supply, laptop, mobile phone and ultra-thin electric appliance.

The transformer consists of an iron core (or magnetic core) and a coil. The coil has two or more windings, of which the winding connected to the power supply is called the primary winding and the rest is called the secondary winding.It can change ac voltage, current and impedance.The simplest core transformer consists of an iron core made of a soft magnetic material and two coils with different turns on the core.
