JB/T 11155-2011 in English

本标准规定了电动机的型号、基本参数、技术要求、试验方法、检验规则、标志、包装、运输和贮存的要求。
本标准适用于低压及中、高压断路器专用的HDZ系列交流、直流和交直流两用电动机，该电动机带有减速机构，可直接驱动断路器操作机构或弹簧操作机构的储能装置，供远距离控制之用。考虑到有一部分断路器采用永磁直流电动机作为驱动源，其原理与交直流两用电动机在直流使用时相同，可参照执行本标准。

Scope

This standard specifies the model, basic parameters and dimensions, technical requirements, test methods, inspection rules, marking, packaging, transportation and storage requirements of special AC and DC motors for circuit breakers. This standard applies to HDZ series AC, DC and AC-DC dual-purpose motors (hereinafter referred to as motors) dedicated to low-voltage, medium- and high-voltage circuit breakers. The motors are equipped with a reduction mechanism and can directly drive the circuit breaker operating (moving) mechanism or spring operation. The energy storage device of the (moving) mechanism is used for remote control. Considering that some circuit breakers use permanent magnet DC motors as the driving source, the principle of which is the same as that of AC and DC dual-purpose motors when used in DC, this standard can be implemented with reference.
