Method for preventing over-heat inside electric appliance by controlling electric consumption and its equipment

Abstract

A method for preventing over-heat inside electric appliance by controlling electric consumption is disclosed. Its device is composed of setting-up unit, sensing unit, CPU, controller unit, alarm unit and power-fail protector unit. The temp. at different points in electric appliance are sensed by the sensing unit and then compared with the set-up values. According to comparison result, a control signal is sent to the controller unit for decreasing or increasing the load of electric appliance.

Description

technical field [0001] The invention relates to a control method and a device for preventing electric equipment from overheating by controlling power consumption. Background technique [0002] General electrical equipment is damaged by overheating, and even disasters occur one after another. In fact, the overheating or overload protection of electrical equipment in the past has continued to use the traditional protection concept. Before the electrical equipment exceeds its tolerable limit value, mandatory isolation is adopted. The method is separated from the power supply system to achieve the protection function. In fact, in this overheating process, the internal material of the electrical equipment has been damaged by overheating and high temperature. After many years, the aging of the material is likely to lose the proper protection function, resulting in It has become the cause of serious disasters, such as fires in building wires... etc. It is often heard that overheati...

[0002] General electrical equipment is damaged by overheating, and even disasters occur one after another. In fact, the overheating or overload protection of electrical equipment in the past has continued to use the traditional protection concept. Before the electrical equipment exceeds its tolerable limit value, mandatory isolation is adopted. The method is separated from the power supply system to achieve the protection function. In fact, in this overheating process, the internal material of the electrical equipment has been damaged by overheating and high temperature. After many years, the aging of the material is likely to lose the proper protection function, resulting in It has become the cause of serious disasters, such as fires in buildings and wires... etc. It is often heard that overheating and aging of electrical equipment is one of the main reasons

[0003] The person shown in Fig. 1 is the circuit 3 of common electrical equipment, is connected several shunt circuits 31, 32, 33, 34 by the main circuit 30... On the circuit, a main switch 301 and shunt switches 311, 321, 331, 311, 321, 331, 341, 332, 342... and other circuit components, and each shunt circuit is connected with loads 312, 322, 333, 343..., etc., as mentioned in the previous paragraph, overheating, aging or even disasters in electrical equipment The reason, the cause is not limited to the overheating or aging of the loads 312, 322, 333, 343...etc. The aging or overheating of other electrical components or accessories such as switches, wires, plugs, etc. is also the culprit of the unfortunate event. However, for The aging and overheating of various components in electrical equipment has always been the most neglected link in protection and monitoring
