specific Embodiment approach 1

[0024] Specific implementation mode one: the following combination figure 1 and figure 2 Describe this embodiment, the heating method for the distribution automation terminal in the alpine region described in this embodiment, the heating method is realized based on the heating device for the distribution automation terminal in the alpine region, and the heating device for the distribution automation terminal in the alpine region includes AT89C51 single-chip microcomputer 1, DS18B20 temperature Sensor 2, heater 3, keyboard 4, display 5, sound and light alarm 6 and regulated power supply 7,

[0025] DS18B20 temperature sensor 2 collects the temperature inside the box of the power distribution automation terminal, the temperature signal output end of DS18B20 temperature sensor 2 is connected to the temperature signal input end of AT89C51 single-chip microcomputer 1, and the heating signal output end of AT89C51 single-chip microcomputer 1 is connected to the heating signal input ...

specific Embodiment approach 2

[0042] Specific implementation mode two: this implementation mode further explains implementation mode one, and the ambient low temperature alarm reference value is -10 degrees Celsius.

[0043] The ambient low temperature alarm reference value can be adjusted according to the safe operation of the equipment.

specific Embodiment approach 3

[0044] Embodiment 3: This embodiment further describes Embodiment 1 or 2, and the upper limit of the normal operating temperature is 5 degrees Celsius.

[0045] The upper limit of the normal operating temperature can be set to the general temperature value required for safe operation of the equipment, so as to ensure that the heater 3 will not be in an overheated state.

Abstract

The invention discloses an arctic-alpine area power distribution automated terminal heating method, belongs to the technical field of power distribution safety and aims at solving the problem of proneness to equipment failure due to low environment temperature when a power transmission automated terminal is used in arctic-alpine areas. The method includes that an environment low-temperature alarming reference value and a normal running temperature upper limit value are input to an AT89C51 single chip microcomputer through a keyboard; the AT89C51 single chip microcomputer compares a current temperature signal value collected and acquired by a DS18B20 temperature sensor with the environment low temperature alarming reference value and the normal running temperature upper limit value; if the current temperature signal value is lower than the environment low temperature alarming reference value, a heater is started for starting; if the current temperature signal value is within a range of the environment low temperature alarming reference value and the normal running temperature upper limit value, a current state is maintained; if the current temperature signal value is higher than the normal running temperature upper limit value, the heater is enabled to stop heating. The arctic-alpine area power distribution automated terminal heating method is used for power transmission automated terminal heating.

Description

technical field [0001] The invention relates to a heating method for a power distribution automation terminal in an alpine region, and belongs to the technical field of power distribution safety. Background technique [0002] When existing distribution automation terminals are used in alpine regions, terminal equipment failures often occur due to low ambient temperature, which seriously affects the controllability and online level of distribution automation terminals. Especially in the environment of sudden drop in temperature, the failure rate of distribution automation terminals has increased significantly, resulting in a large number of terminal equipment being unable to display the operating status of distribution network equipment online in real time, which has brought great security risks to the safe and stable operation of the distribution network. At the same time, repairing faults in severe winter will cause a lot of manpower, material and financial losses. Conten...
