General of thermal relay:
Thermal Relay is a kind of automatic switching component with isolation function, which is widely used in
Remote control, remote measuring, telecom, automatic control, integration of machinery and
Electrification, electric and electronic equipments. It's one of the most important controlling
Components.
Generally, thermal relays have the inductive organ (input part) that can reflect the input value (such as
Current, voltage, power, impedance, frequency, temperature, pressure, speed, light etc. ); Have
The executive organ (output part) that has the capability of switching the controlled circuit "on" or
"off"; Between the input and output parts, there is the medium organ (actuator) that can make
Input value coupling-isolation and drive the output part.
As a kind of controlling component, generally, relay mainly has the following functions
1) To enlarge the range of control. E. G., when the controlling signal of a multi-contacts relay
Reaches a certain value, according to the different forms of the contacts, it can synchronously
Change over, close or open several circuits.
2) Enlargement. E. G., sensitive relays and medium relays can control a high-power circuit with
Minute controlling power.
3) To integrate signals. E. G., when several controlling signals are put into a multi-winding relay in
The stated form, the relay can realize the expectant controlling function by analyzing the different
Signals.
4) Automatization, remote control and monitoring. E. G., in automatic equipments, the relays and
Other electronic components can constitute program-controlled circuit, realizing the automatic
Operation
Applications of thermal relay:
Prepayment energy meter
Smart meter
Concentrated meter reading system
Street lamp control system
Compound switch, Combination switch
Automatic control device/ system
AMR system
Elevator control
