Current transformer in the join, want to note the polarity www.facebook.com/guohong.trading of the first and second coil, transformer using subtractive polarity three phase induction motor marking method in our country. When installation, it is important to note that connection is correct and reliable, and the secondary side are not allowed to answer the fuse or switch. Even if for some reason to dismantle the secondary side of the instrument or other AC motor devices, also must first to secondary side short circuit, then on again. Low voltage switch is refers to under 1 kv isolating switch, circuit breaker, fuse and so on low voltage ac synchronous generator power distribution equipment controlled by load, must branch out, it is forbidden to more than a brake control and confusion. Low voltage power distribution equipment and interlock of self-provided generator which should be reliable. It is strictly prohibited to bring their own power equipment and power grid parallel operation without permission. Low voltage power distribution equipment around before and after the operation and maintenance of channels small diesel engine should be laid on the insulation pad, piled up other items are diesel generator set strictly prohibited in the channel at the same time.

Welding equipment: equipment first, followed by power supply. Dismantle devices: power supply, before equipment. Zero circuit: the first, followed by the line of fire. Down the diesel generator set line: after the first wire, scattered line. Low voltage fuse cannot as the motor overload protection. Fuse rated voltage must be greater than or equal to the working voltage of power distribution lines. Rated current of the fuse must be greater than or equal to the rated current of the melt. Fuse breaking capacity must be greater than the diesel engine possible maximum short-circuit current distribution circuit. Melt the selection of rated current, must meet the line normal working current and the starting current of the motor. For electric and lighting load short circuit protection, the rated current of the melt is equal to or slightly greater than the rated current of the load. For single motor, melt rated current (1.5 2.5) or the motor rated current melt rated current in the power squirrel cage induction motor distribution system, and at a lower level shall coordinate, in order to realize the selective protection purposes. The next level should be smaller than at the next higher level.
