Ceramic plug fuse should be installed vertically, qualified fuse, must be used in other water pump price copper wire, etc. Replace the fuse. Spiral can fuse power into the line on the center of the base terminal, they can pick up the load for the shell of the screw terminals. Replacing the melt, must first disconnect the electric equipment, in order to prevent the cause arc. Fuse line should be installed in each phase. In two phase line diesel generator three and three phase four wire circuits of the neutral line fuse is strictly prohibited. Fuse is used primarily as a short circuit protection fuse for quarantine purposes, the fuse must be installed in the line head end. Fuse is AC motor short circuit protection. Isolated power supply, safety maintenance. Knife switch function is to isolate the power and safety maintenance. Rubber cover porcelain bottom knife switch as general electric lighting, electric circuit control switch, also can be used for distribution of branch circuit switch. Three pole rubber cover auto spare parts knife switch when appropriate to reduce capacity can be used to frequent starting motor control switch operation, not three pole rubber cover knife switch power supply into line should press into the line on the static contact end seat, electric equipment below the outlet of a fuse. Knife switch when cutting condition, the handle should be down, turned on, the handle should be upward, cannot flip or diesel engine paperback, three pole rubber cover knife switch is short circuit protection. Isolated power supply, safety maintenance. 


3 Phase induction Electrical Motor MS Series for winding machine

Specifications
ambient temperature:-15 -40 
above sea level : not exceed 1000m 

rated voltage:+-5% 
Low voltage load switch shell should be reliable grounding. When choosing automatic air switch as main switch, the switch into the line side must have a clear disconnect point, apparent disconnect point can use isolating switch, knife switch and fuse, etc. The main purpose of the fuse is overload or short circuit protection. single phase induction motor Parallel capacitor compensation is directly with the capacitor compensation device and received the same circuit, in order to improve the power factor. There are many measures to improve the power factor, parallel compensation capacitor is the most convenient way. www.facebook.com/guohong.trading The wall switch off the ground should be 1.3 meters 1.3 meters, the wall socket. Pull switch should be 2 -3 meters off the ground. Electricity meter from the ground should be 1.4 1.8 m. Into the door line should be 2.7 meters off the ground. Lane road, a, secondary roads, electricity, major rivers, the low voltage circuit, special cableway, etc, should not have joint. Ming with plastic sheath line is mainly used for indoor installation, may not be directly into the plaster layer in the dark with laying. Wire wear tube general requirements tube total cross-sectional area of the wire (including insulation) is not diesel engine more than 40% of line pipe inner sectional area. Wire tube shall have joint, joint should be within the junction box; Different ac motor power supply circuit and voltage loop, as spare circuit, line work lighting and emergency lighting shall be installed in the same tube.
