Baijian Testing is mainly engaged in textile, insulation, cosmetics, food, hardware industry related product testing, as well as providing product certification services, but also in the broadening of the scope of the testing industry, the laboratory issued a report can be stamped CNAS/CMA/CAL qualification seal, the report is true and effective.
Report qualification: CNAS, CMA, CAL, etc.
Testing costs: Quotation sample size according to customer needs and experimental
complexity: Choose to send samples or come to the door according to the sample size
The damage of an electric motor is mainly caused by overheating or reduced insulation performance of the winding, while overheating of the winding is often caused by excessive current flowing through the winding. There are two main types of protection for electric motors: current and temperature detection. The current detection type protection device thermal relay utilizes the load current to flow through the calibrated resistance element, causing the bimetallic thermal element to bend after heating, thereby causing the relay contacts to act before the motor winding burns out. Its operating characteristics are similar to the allowable overload characteristics of the motor winding. Although the accuracy of the action time of the thermal relay is average, it can achieve effective overload protection for the motor. With the continuous improvement and improvement of structural design, in addition to temperature compensation, it also has functions such as phase failure protection and load imbalance protection. The temperature detection type protection device is a bimetallic temperature relay that is directly embedded in the motor winding. When the motor overload causes the winding temperature to rise to near the limit value, the bimetallic sheet with one contact is heated and bent, causing the contact to open and cut off the circuit
