Delixi CDHR16 series strip fuse disconnector

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 ...

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.

Inverter selection is a skill, if the selection is not appropriate, it may damage the inverter explosion, and seriously affect the normal production of the factory, so it is very important to select the inverter scientifically and reasonably. The following are the principles of inverter selection: ...

1. When the stabilized power supply is powered on, please do not disassemble the stabilized power supply or pull the input and output cables of the stabilized power supply at will to prevent electric shock or other electrical safety accidents. 2. The input and output connections of the regulated power supply must be reasonably arranged, ...

1. There is a problem with a frequency converter, it cannot operate and the LED shows "UV" (abbreviation of under voltage), which clarifies that the alarm in the book is DC bus undervoltage. Since the control loop power supply of this type of inverter is not taken from the DC bus, but from the communication input through the transformer alone...

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) ...

The electrical control system is generally called the secondary control loop of electrical equipment, different equipment has different control loops, and the control methods of high-voltage electrical equipment and low-voltage electrical equipment are also different. Specifically, an electrical control system refers to a combination of several electrical components that are used to complete the operation of a certain ...

What is a Circuit Breaker? What is the function of a circuit breaker? How to choose the right circuit breaker in the work? The circuit breaker is what we often call an air switch. Just like a dam that controls the release of water, when the sluice gate is opened, the flow of water is continuous, and when the sluice gate is lowered, it blocks the flow of water. ...

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 first method is that you can analyze what the cause is according to the condition displayed on the inverter, such as whether the faulty code appears normal, whether there is still running code or not, and still nothing appears (in the case of input power), which means that there is a rectification problem. If you're on standby...

1. Extra limit short-circuit breaking can be used for Icu There are two types of breaking capacity targets for circuit breakers: additional limit short-circuit breaking capacity of 4U and additional operating short-circuit breaking capacity Ics. As a characteristic parameter, ICS is not only a brief consideration of the breaking ability of the circuit breaker, but also a breaking purpose.

What is a Solid State Relay Solid State Relay (SSR) is a pointless switch composed of microelectronic circuits, discrete electronic devices, and power electronic power devices. The barrier between the control end and the load is completed by a barrier device. The input of the solid state relay is micro...

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. ...

1. Failure analysis. 1) Closing fuse, control fuse blowing or poor contact. 2) Poor contact of DC contactor or poor contact of control switch contact and auxiliary contact of circuit breaker. 3) The DC voltage is too low. 4) Closing and locking action. ...

Delixi high-precision fully active AC voltage regulator uses linear integrated circuits to form a control system, controls the servo motor, drives the contact voltage regulator to actively regulate the voltage, and is equipped with delay, overvoltage, undervoltage and overcurrent maintenance functions. The product has high efficiency, the same input and output voltage waveforms, and the output ...

(1) Gain Parameter: The share gain of the speed manipulator. If the gain is too large, it may cause the speed to fluctuate. (2) Integration time parameter: the integration time of the velocity manipulator, that is, the deviation step signal ...

Operation failure is manifested by the dragging or misoperation of the circuit breaker. Because the most basic and important function of the high-voltage circuit breaker is to operate correctly and remove the fault of the power grid quickly. If the circuit breaker drags or malfunctions, it will pose a serious threat to the power grid, first of all: (1)) expand the scale of the incident, which may make the original ...

1. A variety of starting methods Current limiting soft start, voltage ramp soft start, ramp plus current limiting soft start. 2. High reliability Signals in the control system are digitized by high-performance microprocessors. ...

1. The instantaneous high temperature in the grinding process will make the surface of the workpiece reach a molten state, and the steel surface will react with the oxygen in the air chemically, which will form a very thin (20-30nm) iron oxide film.

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 ...
