Accurately three-phase relay measure the ground impedance, ground resistance, and ground reactance of a large grounding network Potential; measure the on-resistance of the down conductor; measure the soil resistivity. The most important thing is to measure whether the resistance of the ground pole t... read more
Car relays get hot. From the perspective of physics, it is a process in which heat is generated by mechanical motion, and mechanical energy is converted into heat. This is a normal phenomenon. This is why a radiator is installed in many machines. A lot of heat is generated during the movement of the... read more
Micro Switch The switch panel and the raised button connected with the switch panel are characterized in that the button is connected to the panel through arc-shaped connecting strips on both sides thereof; the button, the connecting strip, and the panel are preferably integrated injection molding, ... read more
What is the relay used for? Relay is a kind of protection element, an automatic switching element with isolation function. The relay can be used for switching, breaking, and connecting multiple circuits, which can expand the control range. With sensitive relays and intermediate relays, high-power ci... read more
The structure and working principle of an electromagnetic relay are similar to that of a contactor, mainly composed of an electromagnetic mechanism and contacts. Electromagnetic relays are also available in DC and AC. The suction value and release value of the relay can be adjusted within a certain ... read more
