Problems solved by technology
[0005] However, the above-mentioned system can only provide high-temperature early warning for power equipment, and does not have a structural design to quickly respond to abnormal temperature rises. Often, it can only notify the abnormal situation, and it is too late to prevent the occurrence of disasters; at the same time, the above-mentioned system is the same as the existing temperature detection equipment. Similarly, only the current temperature can be detected, and the alarm will be notified when the current temperature exceeds the set value. The predictability of this early warning method is actually insufficient.

The invention relates to the technical field of power equipment temperature monitoring, and provides a high-temperature early warning system of power equipment, which comprises an acquisition module, a control transmission module, an early warning module and an emergency structure, and is characterized in that the emergency module comprises a dry ice steel cylinder arranged on the right side of the top of an inner cavity of a power equipment cabinet; the upper right wall of the inner cavity of the power equipment cabinet is vertically provided with a steel cylinder support plate, according to the system, a temperature rising rate calculation and comparison unit is additionally arranged, whether the temperature rising process of the equipment is normal or not is judged by calculating the temperature rising rate of the equipment and comparing the temperature rising rate with the rising rate under the conventional condition, and therefore the pre-judgment capacity of high-temperature early warning of the electrical equipment is improved; more operation time is increased for subsequent disaster elimination; and through the designed emergency structure, different working conditions can be coped, and the safe use of the power equipment is protected.
Description
technical field [0001] The invention relates to the technical field of temperature monitoring of electric power equipment, in particular to a high temperature early warning system of electric power equipment. Background technique [0002] Power equipment is a power production and consumption system composed of power generation, power transmission, power transformation, power distribution and power consumption. Electricity is supplied to each user. It mainly includes two categories of power generation equipment and power supply equipment. Power generation equipment is mainly power plant boilers, steam turbines, gas turbines, water turbines, generators, point motors, transformers, etc. Power supply equipment is mainly transmission lines and transformers of various voltage levels. , contactor, etc. [0003] When the power equipment is in a high-temperature working state, it will affect its own working life and accuracy, thereby affecting the normal use of the power grid. In t...
