The difference between air switch and leakage protection switch - Delixi

The type of inverter is selected according to the type of production machinery, speed regulation range, static speed accuracy, and starting torque requirements, and it is most appropriate to decide which inverter is the most suitable to use. The so-called suitability is not only easy to use, but also economical, to meet the basic conditions and requirements of technology and production. ...

Regulator problem 1: The regulator cannot be started Reason: Whether the phase sequence of the input power cord has been changed, and the air switch in the machine is not turned on or broken. Repair methods: 1. Swap the two power supply wires arbitrarily or check whether the power supply line is correct; 2. Close or replace the switch. Voltage Regulator ...

The circuit breaker has arc extinguishing equipment, so the circuit breaker can be operated with load, not only the load current, but also the fault (short circuit) current; The circuit breaker has a good package form, so simply observing the circuit breaker cannot intuitively determine whether it is in the closed or disconnected position. Isolate ...

1. First carry out the no-load test operation of the inverter First of all, check whether all the wiring of the inverter is correct, do not connect the output of the inverter to the motor, and conduct a no-load test on the inverter first. Read the user manual of the inverter carefully before powering on to understand the relevant functions and settings, and operate ...

1. What is a switching regulator? Switching regulator, English (regulatior), some people call it a regulator, a voltage regulator source. To achieve voltage regulation, it is the demand control system (negative feedback), from the automatic control theory, we know that when the voltage rises through negative feedback to reduce it, ...

1. If the two branch lines are connected, the current in the zero line flows to each other, which destroys the working current balance in the zero sequence current transformer and causes the leakage protector to malfunction. If you want to use the neutral line of the power branch line as the neutral line of the lighting branch line nearby, it will cause the leakage of the power branch line.

First of all, when the transformer is faulty, we must cut off the power supply of the transformer through abnormal methods for the first time, and many major electrical fires and electric shocks are caused by the main gate is not closed. Now let's take a look at what to do. ...

1. When the main circuit is equipped with a total leakage maintainer, the main barrier switch, the branch barrier switch, the main circuit breaker, the branch circuit breaker or the main fuse, and the shunt fuse should also be installed. When the total leakage maintainer is a leakage circuit breaker with short-circuit, overload, and leakage maintenance functions, it can not be ...

1.AC/DC the use of power supply Schematic diagram of the use of low-dropout linear regulators in AC/DC power supplies. In this circuit, the alternating current is stepped-down by the power transformer to obtain the AC low voltage, and then through the rectifier filter circuit to obtain the unstable DC voltage, and then through the low dropout linear voltage regulation.

01 "O" ring spell In addition to the oil seal problem of the reducer itself, the robot manufacturer will also have an impact on the planning and installation of the reducer components, due to the sealing of the reducer, in addition to the oil seal, there are also O-rings. O-rings are a very common type of product sealing planning.

First, the process of inverter rehabilitation factory value 1. Study the manual and find the corresponding function number, or key combination. 2. Confirm that the parameters can be corrected (sometimes the inverter will set the parameter to write the protection function in order to prevent the parameters from being changed randomly, and the password must be guaranteed to enter the correction) ...

Delixi regulator output voltmeter keeps swinging back and forth, and sparks occur at the carbon brush, and the problem phenomenon and cause analysis 1. The contact pressure between the carbon brush and the coil plane is too small 2. The carbon brush is severely worn Delixi voltage regulator has ...

AC contactor can sometimes be used for a long time can not be suction situation, although this is not a common problem of AC contactor, but AC contactor can not be suction will affect the efficiency of the operation and even damage the production equipment, with the equipment for too long, together without outstanding maintenance, are ...

Variable-frequency Drive (VFD) is an electric power control equipment that uses frequency conversion skills and microelectronics skills to control and communicate motors by changing the frequency of the working power supply of the motor. The inverter is mainly composed of rectifier (communication to DC), filtering, inverter (DC to ditch) ...

Since its creation in the 1970s, which began as a patent for Zap Trap under the pleasant name, surge maintenance equipment (SPD) has become essential in many lightning protection systems (LPS). Surge maintainers are now used in electrical installations to avoid transient overpower ...

1. Resistance Indicates the magnitude of the conductor's resistance to the current. Conversion between units of resistance: 1KΩ=1000Ω R indicates the resistance, and the unit of resistance is: ohms (Ω) R=U/I U--- voltage (unit: volts V) I--- current (in ...

The traditional textile printing and dyeing industry is a labor-intensive industry, and the degree of automation is not high. Most of the transmissions used are not speed regulation, and most of the occasions that need speed regulation are DC motors, such as warping machines, sizing machines and many printing and dyeing equipment.

1. The quality of the socket is low First of all, we should check whether the socket is a miscellaneous defective product, the copper clamping force in the defective socket is not enough, resulting in a poor connection between the socket and the plug, and the socket and plug will heat up after a long time of electrical use. Therefore, you must not buy cheap miscellaneous electric ...

Delixi circuit breakers and contactors are used to make and break circuits. The rated current of the circuit breaker is generally greater than that of the contactor (the maximum current medium voltage contactor is 630 A); The circuit breaker has excellent short-circuit current breaking capability (now the maximum capacity of the medium voltage system is 80KA), and the contactor needs to cooperate with the fuse...

The high-voltage circuit breaker (or high-voltage switch) is the primary power control equipment of the substation, which has arc extinguishing characteristics. When the system is in normal operation, it can intercept and connect the no-load and load currents of lines and various electrical equipment. When there is a problem in the system, it can quickly block the fault with the cooperation of relay maintenance.
