1·Every machine is equipped with protect travel switch in order to increase safety coefficient for repairing and maintenance. It also has thermal overload relays to protect the motor.

每台机器均配有保护行程开关，为维修、保养增加一份安全系数。且装有热过载继电器，保护电机。

2·So the overload control of MGW in Soft-Switch researched in this paper is a kind of feedback model for service traffic control mechanism which is composed by MGW and MGC together.

因此本文研究的软交换体系下媒体网关过载控制是一种由媒体网关和媒体网关控制器共同作用构成的反馈型业务流量控制机制。

3·And installed the overload protection, namely to ensure that motor and pump load pressure switch.

并安装了超载保护，即保证电机及油泵负荷的压力开关。

4·Comfortable and convenient operation, assembly thermal overload protection device and multi-file electronic speed constant power switch ensure high motor efficiency and durability.

操作舒适方便，装配过载过热保护装置，多档电子调速恒功开关，保证马达的高效率和耐用性。

5·Motor with overload protection switch, easy, safe and reliable feed set or sealed to prevent the bulk material outside the very mechanical;

电机设有过载保护开关，操作简单，安全可靠，进料部位采用密封设置，防止散料非常机械外；

6·High-power static bypass switch, overload automatically switch to bypass when the power supply, zero switching time;

大功率静态旁路开关，过载时可自动转旁路供电，零切换时间；
