Delixi time control switch adjustment

1. Is it possible to put the motor directly into a fixed frequency inverter without using soft start? It is possible at very low frequencies, but if the given frequency is high, the conditions for direct starting of the power supply are similar. A large starting current (6-7 times the rated current) will flow too much, due to ...

1. Trial delivery and commissioning method The first thing to find is the fault of the remaining current action maintainer itself. The detailed operation method is: first block the power supply, and then remove all the zero-sequence transformer load side leads of the remaining current action maintainer (the second and third level remaining current action maintainers will directly remove the outgoing ...

1. Before the inverter device is in place and debugged, please tighten the components, especially the connecting bolts of the wire part, if not tightened, the connection will be heated and cause fire. 2. The on-site planning of the installation should be reasonable, and the excellent ventilation environment should be maintained. 3. The incoming and outgoing power lines of the inverter are not ...

1. Avoid water and air entering the transformer (1) The transformer should be protected from water ingress and moisture during operation, and it is necessary to seal well the cap of the casing item, the top of the storage phase, the bushing pipe and its connecting pipes. If necessary, a leak detection test should be carried out, and if the insulation has been found to be damp, it should be adopted in time.

First, the iron core may not be able to suction power Causes: The power supply voltage is too low or fluctuates too much, the power supply capacity of the operating circuit is lacking or the wire is broken and the control contact is poor, the technical parameters of the coil are inconsistent with the application conditions, and the product itself is damaged. Solution: Turn up the power ...

Delixi leakage maintainer, as a common anti-shock equipment, can quickly disconnect the circuit in the face of leakage, overload, short circuit and other problems in the electrical circuit, useful maintenance personnel safety, to prevent damage to electrical equipment. Volume...

We are able to compare the values of resistance and hose diameter (conductance vs. practical diameter). When it comes to metal wires, this analogy works well. Small-diameter wires have a higher resistance than large-diameter wires made of the same metal. The standard unit of resistance is ohms, there are ...

The operation of differential thermal analysis is simple, but in practical work, it is often found that the same sample is measured on different instruments, or different samples are measured on the same instrument, and the results of the differential thermal curve of industrial electrical appliances are different. The high temperature, shape, area, and size of the peaks will all change. ...

　　Seriously affect the normal operation of the inverter. The core components of the inverter are IGBT power semiconductor switching components. When they are working properly, they generate a lot of heat. If there is no fan forced cooling, the sensing head will immediately detect (IGBT) overheating (IGBT) and send it ...

Circuit breakers account for a very large proportion of electrical sales and have a wide range of applications, but there are different standards for circuit breakers. For example, 1P, 1P+N, 2P, etc., there are also differences between them. 1. 1P circuit breaker, it is a single-stage ...

In the use of soft starters, some users often have some faulty concepts such as: 1. It is thought that whether the motor can start successfully is related to the function of the soft starter, and a good brand or even a foreign brand should be selected under heavy load. 2. When the motor is not ...

Quickness: It means that the maintenance device should be able to remove the short-circuit fault as soon as possible, and its purpose is to improve the stability of the system, reduce the damage to the faulty equipment and lines, reduce the scale of the fault, and improve the effect of active reclosing and active investment of standby power supply or standby equipment. Reliability: Refers to ...

Delixi's communication contactor is widely used in industrial electrical, contactor as a kind of electromagnetic switch, its interior is mainly composed of the main and auxiliary contacts and electromagnetic coils, static cores and other parts of the control line connection and breaking. ​ ...

The low-voltage air circuit breaker is the primary equipment for low-voltage power distribution, and it should be able to operate reliably when the electrical equipment is no-load, load-loaded or short-circuited. Its primary function is to maintain the line and equipment, can turn on, carry and break the current under normal circuit conditions, and can also be used in the specified non-...

Delixi's three-phase circuit breaker is generally divided into three types, namely 3P, 3P+N and 4P. (1) Differences: 3P: Only three wirings are used for pure three-phase electrical equipment, which trips when there is no single-phase load to the ground or when there is a short circuit between phases; Otherwise, when a one-phase N-line load occurs, the N-line is disconnected ...

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) ...

Many people don't know what a surge is, surge is also known as a surge or lightning protection maintainer, the first is to maintain the household electrical equipment when it rains and thunders to avoid being damaged by lightning, and when the lightning strikes high-voltage electricity is drained to the ground through the surge maintainer, it will not directly hit the electrical equipment ...

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...

1. Although the air switch is a type of circuit breaker, it is a switch that will automatically disconnect as long as the current in the circuit exceeds the rated current. However, air switches are used in low-voltage distribution networks and electric traction systems, mostly on the low-voltage side. Widely used in the home, such as general household switches ...

Grounding current, also become quiescent current, load regulation (the smaller this value, the stronger the LDO can press the load) linear regulation (the smaller, the less influence of the input voltage on the output voltage, the better the LDO function) power supply ratio (PSSR), reflecting the Delixi LDO to the interference signal ...
