The relay that controls the original is to control the closing action by generating the minimum current for the pull-in action. Generally, in use, the given current needs to be slightly larger than th...
With the rapid development of the industry, with the development of new electric energy meters, magnetic latching relays have also ushered in rapid development. Relays have become an indispensable and...
From the perspective of structure and working principle, the magnetic latching relay is an automatic switch, and it is also a new type of relay developed in recent years. The magnetic latching relay h...
In the operation of power transformation and distribution, transformers are indispensable. It is very necessary to be familiar with and master the basic knowledge of transformers. The basic knowledge ...
A transformer is a device that transforms AC voltage, current, and impedance. When an AC current is passed through the primary coil, an AC magnetic flux is generated in the iron core (or magnetic core...
What is the difference between Hall current sensor, transformer, and shuntHall current sensor: It is a sensor that uses the Hall effect to convert a large current into a secondary tiny voltage signal....
Magnetic latching relay is a new type of relay developed in recent years, and it is also an automatic switch. Like other electromagnetic relays, it automatically turns on and off the circuit. The diff...
The electromagnetic relay is a relay that drives the movable part of the magnetic circuit by the electromagnetic attraction generated by the control current through the coil to realize the contact ope...
The electricity consumption is more than before, and there may be several factors as follows:(1) With the continuous acceleration of urban and rural power grid transformation in recent years, the qual...
When the electric meter has an alarm failure, the smart electric meter will remind the user with a liquid crystal display and an alarm light. When the electric meter is in an alarm state, it needs to ...
Precautions for the use of DC ammeter1. The ammeter should be connected in series in the circuit.2. Choose the appropriate range according to the measured current. For an ammeter with two ranges, it h...
1. There are certain differences in the structure between them. The current transformer is generally made of thick wire. It should be used in series with the load that measures the current, and the v...
