How the time relay works
Time relay refers to a relay whose output circuit needs to change significantly (or contact action) after adding (or removing) the input action signal within the specified accurate time. It is an electrical component used in lower voltage or lower current circuits to turn on or off higher voltage and higher current circuits. With the […]
This is the right way to use the travel switch!
In engineering applications, there are many devices used as circuit on-off control, such as buttons, relays, sensors, etc., and the travel switch is one of them. The working principle of the travel switch is similar to that of the button, the difference is that the button is on and off by pressing, while the on […]
The reason for the total burnout of the inverter with the motor
1. When the motor current in the inverter is set too large, the motor protection parameter is set too large, and the inverter cannot protect the motor according to the actual current of the motor when the motor is overloaded, which will cause the motor to overload, heat, or burn. 2. When the motor speed […]
What occasions are the travel switches mainly used for?
The travel switch is suitable for control circuits with AC voltage to 500 volts or DC voltage of 440 volts and current below 5A, converting mechanical signals into electrical signals. To control the stroke of moving parts or realize program control. Limit switches with contacts work similarly to pushbuttons. Essentially the same as a button, […]
Can a high-power soft starter bring a small motor?
What if there is no suitable soft starter, can a high-power soft starter bring a small motor? Generally, the specifications of low-voltage motor soft start are 5.5-600KW, which are mainly used for starting and running protection of different power motors. Power cabinets using soft starters do not need to add other motor protection products, and […]
Self-resetting switch principle
The automatic reset switch is simply a switch that can reset automatically. The reset switch can be cylindrical or square, etc. It is no different from an ordinary switch in appearance, but it is different in function. The difference between the reset switch and the self-locking switch: after the reset switch is pressed, the hand […]
What is the principle of three-phase inverter
1. The main circuit is the power conversion part that provides voltage regulation and frequency regulation power supply for the asynchronous motor. The main circuit of the inverter can be roughly divided into two categories: the voltage type is the inverter that converts the DC of the voltage source into alternating current, and the filter […]
Travel switch kw6 product description
The soot blower stroke (limit) switch KW6 controls the reciprocating motion and purging rotation of the helical pipe or pipe. The soot blowing process is controlled by the KW6 travel switch of the electrical box at the rear end. After the predetermined number of soot blowing cycles, the control system reverses the motor, the nozzle, […]
What are the reasons for the soft start of the motor to burn out?
With the development of modern science and technology to today’s level, soft starters, as one of the most common products in the electronics industry, also encounter some faults that should not occur, such as motor soft start burnout. This kind of failure is often related to the assembly level of the soft-start manufacturer and the […]
How to choose a travel switch
There are many types of travel switches, but the basic structure is the same, mainly composed of three parts: the contact part, the operating part and the reaction force system. According to the different movement characteristics of the operating part, the travel switch can be divided into direct-acting type, roller type, micro-moving type, and automatic […]
