核电站桥式起重机卷绕系统的设计

Polar crane for nuclear power plant moves on the circular orbit that laying the upper of the reactor plant. It is one of the important hoisting equipments in nuclear power plant.

核电站环行起重机沿着位于反应堆厂房上部的环形轨道行驶，它是核电站中的重要起重设备之一。

The invention discloses a transporting system, which comprises a base, a crane, a withdrawing device of power leads, and power leads.

本发明公开了一种适用于无尘环境中的搬运系统，此搬运系统包括基座、吊车、电源线收纳装置以及电源线。

The polar crane for nuclear power plant runs on a circular orbit on the top of the reactor plant, lifts the pressure vessel cover and components for reactor, and the positioning accuracy of polar crane must be strictly controlled.

核电站环行起重机运行于核反应堆厂房上方的环形轨道上，用于吊运反应堆压力容器顶盖和堆内构件，对其吊装定位精度要求极高。

If contacts of some contactor to start a motor are soldered fusing in a crane, the crane will suddenly be started at time of closing the main power switch.

如果一台起重机中的接触器触头发生熔焊，在总电源开关合闸时，这台起重机的电动机就会突然起动，就可能发生意外碰撞事故。
