Power equipment and high-temperature self-protection method thereof

Abstract

The invention provides power equipment and a high-temperature self-protection method thereof. The power equipment comprises a completely-sealed housing, a plurality of functional modules arranged in a cavity enclosed by the housing and a main chip for controlling the all functional modules to operate. The main chip has a function of automatically regulating the working frequency per se and coordinating the work of the functional modules. Each functional module comprises a temperature control module and a plurality of communication modules, such as a WiFi (Wireless Fidelity), an LAN (Local Area Network), a GSM/GPRS (Global System For Mobile Communications/General Packet Radio Service), a PLC (Programmable Logic Controller), an RS485 (Radio Station), and the like. The temperature control module is in charge of detecting the temperature in the cavity of the equipment, comparing the temperature with the threshold preset inside the temperature and informing the compared result to the main chip in an electric signal manner; and the main chip regulates the working frequency per se and the working mode of each functional module according to the received signal and further regulates the internal power consumption and the heating quantity of the equipment. The service life of the power equipment can be greatly prolonged without an air window and a fan.

Description

technical field [0001] The invention relates to electric equipment, in particular to the automatic adjustment of the internal working temperature environment of the electric equipment. Background technique [0002] Since power equipment works in an unattended outdoor space for a long time, it faces harsh environments such as high temperature, severe cold, rain, and dust. At the same time, as power electronic equipment, it must require stable performance and low cost. Therefore, electrical equipment must have a complete automatic adjustment mechanism for the internal working temperature environment. [0003] Generally, all kinds of electrical equipment use fans, louvers and heat conduction channels to deal with heat generation. Due to the existence of air windows, water vapor and dust are more likely to enter the interior of the power equipment, which will affect the performance of the electronic components inside the power equipment, and then affect the performance of the e...
