Delixi leakage circuit breaker identification method

Currently, there are many different switching regulator topologies. Some topologies are widely used, such as the classic buck converter, also known as the buck converter. However, there are also some lesser-known switch-mode DC-DC converters that include Zeta topologies. These topologies are divided into fundamental topologies ...

There are two speeds of Delixi inverter, one is the target speed, and the other is the speed of practice. The target speed requires the value of the detailed parameters to be adjusted, such as the *** high frequency/*** high frequency in the inverter parameters; Regarding the practical output speed, the frequency needs to be checked in the inverter parameters ...

When the VFD is viewed regularly, the power supply should be blocked, the operation of the VFD should be stopped, and the cover of the VFD should be removed. The first thing is to check the places that cannot be seen without downtime, or the places where it is difficult to find problems on a daily basis, as well as the inspection and adjustment of electrical characteristics. After blocking the VFD power supply, the main power ...

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.

1. The difference between power distribution appliances and control appliances Power distribution appliances: As the name suggests, it is a device that distributes electricity. Electricity, after coming out of the generator, is output by the bus, and can not be directly connected to the power equipment, and the demand is first output into the power station, which is the power distribution equipment, which is ...

The role of a voltage regulator is to convert an unstable DC voltage into a stable DC voltage. However, the integrated voltage regulator has a wider and wider range of applications due to its advantages such as small size, good voltage regulation performance and perfect maintenance function. There are two types of integrated voltage regulators: linear power supply regulators and switching power supply regulators.

The so-called "left zero and right fire of the circuit breaker" is nothing more than the order of the sockets - when facing the socket, the socket on the left is the neutral line, the socket on the right is the front, and that's it. Delixi socket wiring may not be "left zero right fire". ...

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.

There are many types of three-phase communication regulators in Delixi, the most commonly used ones are SJW and SBW, etc., so we need to pay attention to the process of application: First of all, it must be operated correctly according to the instructions of the voltage regulator.

Delixi solid state relay and Delixi communication touch device are more used products, so what are the advantages of solid state relay compared to communication touch device, how should we choose when we can choose? 1. First of all, solid...

Thermal accounting requires information such as power loss, thermal resistance of the package, and ambient temperature. The power loss is calculated in the same way as the efficiency accounting, which is simply the value of the difference between the output input voltage and the input current. Thermal resistance should have a technical standard documented, and if it is not available, it is necessary to consult the manufacturer. Basically...

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...

Although this is not a common problem of AC contactors, the inability of AC contactors to engage will affect the efficiency of the operation and even damage the production equipment.

1. There is no output, no voltage indication or no start when the machine is turned on. Overvoltage or undervoltage maintenance 1. Adjust the internal output voltage adjustable potentiometer 2. The wrong phase and the lack of phase are maintained, and the two phases are arbitrarily replaced by three phases 3. The main control circuit board is broken 3. Replace 4. The output AC has been ...

The circuit breaker insulation incident can be divided into the internal insulation terminal and the external insulation incident. The hazards caused by internal insulation incidents are generally greater than those of external insulation. (1) Internal insulation incidents The internal insulation end is mainly a bushing and a current transformer ...

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. If the two branch lines are connected, the current in the zero line flows to each other, which destroys the operating current balance in the zero sequence current transformer and causes the leakage maintainer 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.

1. The use environment of regulated power supply requires good ventilation, no moisture, no corrosive gas, explosive substances, conductive dust Egypt steam, etc., and it is required to be installed in places without intense oscillation. ​ 2. The voltage regulator is used according to the function of the electrical equipment.

Delixi general switching power supply can provide stable DC output products, widely used in communications, LED displays, industrial control, radio and television, computer networks, medical equipment, intelligent monitoring and other fields. Delixi universal switching power supply SA, DA, TA, QA Type 85 - 132 / ...

Three-phase communication servo motors are widely used, but after long-term operation, various problems will occur. Timely identification of the cause of the fault and corresponding treatment is an important task to prevent the spread of the fault and ensure the normal operation of the equipment. One...
