Main circuit terminal wiring 1. The three-phase input power is connected to the R, S, and T input terminals of the motor soft starter after passing through the circuit breaker. There is no phase sequence requirement for the three-phase power supply. 2. To control the running and stopping of the motor soft starter, the run and stop keys on the operation panel or an external control loop should be used. 3. The motor soft starter is connected to the bypass electromagnetic contactor, and the phase sequence of the bypass connection is consistent and corresponding. 4. Capacitors and surge absorbers shall not be installed between the output terminals of the soft starter and the motor. 5. The grounding terminal of the motor soft starter must be well grounded. Test run confirmation and parameter setting 1. Confirm that the use environment and input power meet the requirements of product technical performance and design. 2. Confirm that the wiring is correct, especially the input wiring of the power supply. 3. Confirm that there is no short circuit or short circuit to ground between terminals and live parts. 4. Confirm that all terminals, connectors, and connecting bolts are fastened and there is no looseness. 5. After the test run is checked and confirmed, according to the technical requirements of the electrical equipment, set and debug the function operation parameters and fault protection parameters according to the user manual. www.shuyitop.com; Tel/Fax: 0086-577-62840011 WhatsApp: 008613355775769 #softstarter #motorsoftstar #softstarters #softstartechnology #softstartermarket #softstarterprice #ac powersoftstarterwithbuilt-inbypass #builtinbypasssoftstarter #singlephasemotorsoftstarter #ZJSHUYI #Chinashuyi #shuyitop

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
