The development of intelligence, for the field of family life is the whole house intelligence, the whole house intelligence originated in the smart home. Based on the Internet of Things technology, the home ecosystem composed of hardware, software systems, and cloud computing platforms is based on residential buildings. It can realize the functions of remote control of equipment, interconnection between equipment, and self-learning of equipment. User behavior data provides users with personalized life services, making home life safer and more comfortable, but from another perspective, digital and intelligent, at the same time, taking into account the requirements of energy saving, then a new product application scenario will come out, that is, the building intelligent controller, which can dynamically subdivide the power consumption of the whole family in real time, so as to optimize and achieve the purpose of energy saving. So the building intelligent controller to do UL certification, how to do it?
UL 60730, mainly to evaluate the electrical safety of building intelligent controller, to avoid the occurrence of fire and electric shock problems. For the calculation of electricity, there is no evaluation. This part belongs to the UL certification field of smart meters, and there are other UL standards to evaluate.
Building intelligent controller to do UL certification, in the structure of the note:
1. Unlike UL 1472 and other standards, UL 60730 does not require Air Gap Switch;
2. The plastic flame retardant grade of the shell is still relatively high, because it is a strong electric part, and the plastic grade of the shell needs to reach 5VA, which is one of the more demanding parts of UL 60730;
3. Like other UL certification standards, relays still require load types and parameters to be matched. If they do not match, they can be evaluated by adding tests;
4, the electrical clearance needs to meet the UL 60730 standard requirements.
Building intelligent controller to do UL certification, in the test aspects of the note:
the evaluation method is basically the same as that of the traditional UL standard. It still evaluates whether the building intelligent controller has the risk of leakage or fire in actual use from the aspects of temperature test, insulation test, short circuit test, overload test, etc. Since the building intelligent controller is located at the front end of the power system, the current is relatively large. In the process of UL certification, temperature test and overload test are two tests with relatively high risks, special care and attention is required.
