ZJSHUYI Can the DC-AC base of the intermediate relay be universal?www.sh...

Whether the intermediate relay is DC or AC, the working principle is the same, the only difference is the voltage level. The working principle of the intermediate relay is the same as that of the relay and the AC contactor. When the contactor coil is energized, the coil current will generate a magnetic field, and the generated magnetic field will cause the static iron core to generate electromagnetic attraction to attract the moving iron core and drive the AC contactor point action, normally closed contact is disconnected, normally open contact is closed, the two are linked. When the coil is powered off, the electromagnetic attraction disappears, and the armature is released under the action of the release spring, so that the contacts are restored, the normally open contacts are disconnected, and the normally closed contacts are closed.

ZJSHUYI How to choose the inverter.www.shuyitop.com; #frequencyinverter ...

First of all, when selecting an inverter, the power of the motor should be the basic principle. The rated capacity of the inverter is generally marked with KW and current. Under normal circumstances, when selecting an inverter, the corresponding three-phase general-purpose inverter is selected based on the rated KW of the motor. For example: fans, pumps and other equipment. Generally, when selecting a motor of grade 6 or above, it needs to be properly enlarged. The load needs to be controlled by a motor with a reducer, and the power of the inverter needs to be appropriately amplified. For example: cranes, coal mine winches and other equipment. The selection of the inverter should also be based on the load characteristics. If it is applied to frequent startup, the instantaneous current fluctuates greatly, or the load is heavy, the inverter with one or two gears larger can be selected. For example: sand making machine, ball mill and other equipment. When the occasion used for control is

(1) If the two power sources are installed in the same place and share the same low-voltage power distribution cabinet, a four-pole switch shall be used for the incoming circuit or the switching circuit of the dual power sources. (2) The dual-circuit distribution transformers serve as backup power sources for each other, or the transformers and diesel generators serve as backup power sources for each other, and the neutral points of the transformers and generators are directly grounded nearby. If two sets of power supplies share a low-voltage power distribution cabinet, the incoming circuit should use a four-pole switch (3) If the two sets of power supplies are in the same room (common ground), but do not share low-voltage power distribution cabinets, the power transfer switch in the secondary power distribution equipment can be a three-pole switch Web: www.shuyitop.com; Tel/Fax: 0086-577-62840011 Wechat/WhatsApp: 008613355775769 #ZJSHUYI #Chinashuyi #shuyitop #swtiches #Dualpower

ZJSHUYI Do you know what is a fire control cabinet? www.shuyitop.com; #S...

Fire control cabinet (automatic control cabinet) is a kind of industrial control equipment that is more common in our lives, such as corridors, underground parking lots, gas stations and other public places. However, many friends do not know what it is called or what it is used for. The following ZJSHUI editor will explain what is a fire control cabinet. The fire control cabinet is a safe fire fighting tool provided by the pump factory. Its main purpose is to protect the pump motor from overvoltage, short circuit and overload. And also has a sound and light alarm function. It plays an important role in extinguishing fire and is also a fire safety device that can help control the fire after a fire occurs. There are many ways to start the control cabinet, including direct start, soft start, star-delta start, auto-coupling start, etc. www.shuyitop.com; Tel/Fax: 0086-577-62840011 WhatsApp: 008613355775769 #softstarter #motorsoftstar #softstarters #ZJSHUYI #Softstartcabinet
