1. Factors of geographical location and climate
It mainly refers to factors such as altitude, ambient temperature, humidity, and electromagnetic interference. Considering the universal applicability of the control system, it must be taken into account for many years
Due to the particularity of reliable operation for many months, the key parts of the device must be selected with high insulation and strong electrical resistance of the fully sealed type (metal cover sealed or plastic sealed type, metal cover sealing products are better than plastic sealing products) intermediate relay products. This is because only hermetically sealed relays have excellent long-term resistance to harsh environments, good electrical contact stability, reliability and switching load capacity (independent of external climatic conditions).
2. Mechanical action elements
It mainly refers to stress-acting factors such as vibration, shock, and collision. For the control system, the ability to resist seismic stress and mechanical stress is mainly considered, and it is advisable to choose a small intermediate relay with a balanced armature mechanism.
3. The input parameter element of the excitation coil
It mainly refers to the parameters such as over-excitation, under-excitation, isolation of low-voltage excitation and high-voltage (220 V) output, influence of temperature change, long-distance wired excitation, electromagnetic interference excitation, etc., which are all factors that must be carefully considered to ensure the reliable operation of power system automation devices. Excitation according to the excitation amount specified by the small intermediate relay is a necessary condition to ensure its reliable and stable operation.
4. Contact output (interchange circuit) parameter elements
It mainly refers to the nature of contact load, such as lamp load, capacitive load, motor load, inductor, contactor (relay) coil load, resistive load, etc.; Contact load value (open circuit voltage value, closed circuit current value), such as low level load, dry circuit load, small current load, high current load, etc.
Any automation equipment must really determine the actual required load nature and the size of the load value, and it is particularly important to select the appropriate relay products. The failure or reliability of the relay mainly refers to whether the contact can complete the specified switching circuit function. If the actual load of the switch is not the same as the switching load specified by the selected relay, reliability will not be possible.
