1.Product Name: Combined Electrical Fire Monitoring Detector.
2.Executive standard: GB142872-2014
gb14287.3-2014
3.Key components: temperature sensor, current sensor.
4.Product features:
By monitoring and managing the fire hazard parameters such as residual current, wire temperature, overcurrent, and overvoltage of the distribution circuit, the occurrence of electrical fires can be prevented, and the real-time monitoring of a variety of power parameters is realized, providing data for energy consumption management.
5.Place of use:
This system is suitable for large shopping malls, high-end living quarters, production bases, office buildings, shopping malls, hotels, densely populated public places, etc., for monitoring the insulation state of low-voltage distribution lines and electrical equipment, and is installed in the distribution box cabinet of distribution line hierarchical protection.
6.Certification mode: type test + initial factory inspection + post-certification supervision (voluntary certification).
7.Principles of unit division:
1) The main circuit design is different, and it cannot be used as a unit;
2) The temperature sensor is different and cannot be used as a unit;
3) The current sensor category is different and cannot be used as a unit.
8.Inspection cycle: 90 days for type test, 60 days for typing test, 30 days for supervision and inspection.
9.Number of inspection samples: 5 type tests, 2 typing tests, 2 supervision and inspection.
