The AC contactor uses the main contact to open and close the circuit, and uses the auxiliary contact to execute the control command, so as to complete the power switch and control circuit. Normally, the main contact generally has only normally open contacts, and the auxiliary contact often has two pairs of normally open and normally closed functions of the contact. Next, it is described in detail through its composition, classification, basic parameters, selection parameters, operation and maintenance. It is mainly composed of four parts :(1) electromagnetic system (2) contact system (3) arc extinguishing device (4) insulation shell and accessories The selection parameters of AC contactor include: rated voltage; Rated current; Rated voltage of the coil; Frequency of operation; Working current of auxiliary contacts. Here is also an introduction to the points of attention in the selection of rated current: continuous operation of contactor, according to the selection of 67-75%, for exam...

The phenomenon of inverter overcurrent (1) When restarting, it trips as soon as the speed increases, which is a very serious phenomenon of overcurrent. The main reasons are: the load is short-circuited, the mechanical parts are stuck; the inverter module is damaged; the torque of the motor is too small, etc. (2) It jumps when it is powered on. This phenomenon generally cannot be reset. The main reasons are: the module is broken, the drive circuit is broken, and the current detection circuit is broken. (3) When restarting, it does not trip immediately but during acceleration. The main reasons are: the acceleration time setting is too short, the current upper limit setting is too small, and the torque compensation (V/F) setting is high. www.shuyitop.com; Tel/Fax: 0086-577-62840011 WhatsApp: 008613355775769 #VFD #INVERTER #frequencyinverter #frequencyconverter

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
