Description
Technical Field
The utility model particularly relates to an energy-saving self-holding low-voltage relay.
Background
A relay is an electric control device that generates a predetermined step change in a controlled amount in an electric output circuit when a change in an input amount (excitation amount) meets a predetermined requirement. It has an interactive relationship between a control system (also called an input loop) and a controlled system (also called an output loop). It is commonly used in automated control circuits, which are actually a "recloser" that uses low current to control high current operation. Therefore, the circuit plays the roles of automatic regulation, safety protection, circuit conversion and the like. Compared with the traditional alternating current contactor, the energy-saving self-holding low-voltage relay saves more than 95% of electricity, and has very obvious energy-saving effect.
The traditional low-voltage relay is based on the working principle of 'power-on suction, charged keeping and power-off release', more than 90% of energy consumption is concentrated on magnetic hysteresis loss, eddy current loss and short circuit ring loss of an iron core in the running process, the power factor is low, the coil temperature is increased, and the service life of a relay coil is shortened. In the relay control circuit, when the power is switched on, all relays in the circuit are in a restrained state, namely, the attracted relays are attracted at the same time, the relays which are not attracted can not be attracted due to the limitation of a certain condition, and the working mode becomes a parallel working mode.
