针对传统矿用开关电器温升试验设备输出能力的不足,依据矿用组合开关电器产品输出回路数多、各回路间额定电流大小不同等特点,设计了一种适用于矿用组合开关的多回路温升试验系统。给出了系统硬件和软件的设计方案,介绍了回路电流调节装置的设计方案和原理。
Aiming at the shortcomings of the output capacity of the conventional temperature rise test equipment of mining switchgear, based on the characteristics of multi-output circuit number of mine combined switchgear and different current rating of each loop, a multi-circuit Temperature rise test system. The design scheme of system hardware and software is given, and the design scheme and principle of loop current regulator are introduced.
