Embodiment Construction

[0015] The following examples are further explanations and illustrations of the present invention, and do not constitute any limitation to the present invention.

[0016] refer to figure 1 , the load thermal protection module with adjustable multi-point temperature control of the present invention includes a temperature sensor 10, a current transformer 20, a relay 30, a button 40, a microprocessor 50, a power interface 60, a load interface 70, a sampling circuit 80 and a signal input circuit 90.

[0017] Such as figure 1 , figure 2 As shown, the temperature sensor 10 ( RT1 ) is a non-contact temperature sensor, which is used to detect the temperature of the load. The temperature sensor can be a thermistor, or a resistance temperature detector (RTD) or an IC temperature sensor. In this embodiment, the temperature sensor is a resistance temperature detector, which is connected to the microprocessor 50 through a signal input circuit 90 , and send the measured load temperatur...

Abstract

The invention provides a load thermal protection module with adjustable multi-point temperature control. The load thermal protection module comprises a temperature sensor, a current transformer, a relay, a button, a microprocessor, a power supply interface and a load interface. The current transformer is connected with the load interface and is connected with the microprocessor through a sampling circuit. The relay is connected between the power supply interface and the load interface and is connected with the microprocessor. The temperature sensor is connected with the microprocessor through a signal input circuit. The button is connected with the microprocessor. According to the load thermal protection module, different working temperature and current values can be set and stored, when the current transformer detects that load current reaches a set value or the temperature sensor detects that load temperature reaches a set value, the microprocessor controls the relay to cut off a load circuit, and the overcurrent and overtemperature protection of the load is realized. According to the load thermal protection module, the temperature and current of the load can be accurately measured, large power output can be controlled, the double protection of overcurrent and overtemperature of the load can be carried out at the same time, and the application range is wide.

Description

【Technical field】 [0001] The invention relates to an over-temperature and over-heat protection device for an electrothermal load, in particular to an adjustable multi-point temperature-controlled load thermal protection module that can set temperature and current according to different loads or different temperature protection requirements. 【Background technique】 [0002] Various electrical equipment are used in industrial production and people's life. The performance of electrical equipment is not only reflected in its function, but more importantly in its safety. When the electrical load fails, it will cause the load to overheat and overheat. When the temperature exceeds the normal value, the load will be short-circuited, burned, etc., which will affect the normal use of the load. For this reason, the general load is equipped with a temperature switch or a thermostat, so that when the load temperature exceeds the set value, the power supply is cut off to protect the safe...
