The choice of Delixi miniature circuit breaker

It shows that the voltage regulator base is not voltage corrected, and the voltage regulator in this situation is like a transformer, the higher the input voltage, the higher the output voltage, the input decreases and the output voltage also decreases. This...

1. Poor device If the terminal posts of the leakage protector are not firmly connected during the installation, it will often lead to the heating and oxidation of the terminal post for a long time, so that the wire insulation layer will be scorched, and accompanied by the smell of ignition and rubber and plastic burning, forming an undervoltage of the line and tripping the leakage protector. ...

According to the controlled target and operating parameters such as voltage, current, power, frequency and operating system, the additional parameters of the contactor are determined. 1) The coil voltage of the contactor should generally be lower, so that the insulation requirements of the contactor can be reduced, and it is safer to use. But for the sake of the party ...

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 / ...

1. The pressure of Delixi inverter system is unstable and simple vibration? Answer: The pressure of the system is unstable, which may be due to the following reasons: A. There is a problem with the orientation of the pressure of the pressure sensor collection system, the pressure collection point is too close to the water pump outlet, and the pipeline pressure is affected by the water outlet ...

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.

In the process of practical speed regulation, an ordinary AC power supply with adjustable frequency can not meet the requirements of speed regulation and control of asynchronous motors, and must also take into account the effective use of the motor magnetic field, the pressing starting current and the desired torque characteristics, such as low-frequency torque characteristics.

(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 ...

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 ...

(1) Ferromagnetic resonant communication regulator: a communication regulator composed of a full choke and a corresponding capacitor, with constant voltage voltammetry characteristics. The full type is a typical structure in the early stage of this type of regulator. It has simple structure, convenient production, wide allowable scale of input voltage, reliable operation, and overload energy.

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...

Contrasting method The specific method is to let the problematic meter and the normal meter operate under the same conditions, and then detect the signals at some points and compare the two sets of signals measured, if there are differences, you can conclude that the fault is here. This method requires maintenance personnel to have considerable knowledge and skills.

1. Overcurrent (short circuit) Overcurrent problems are the most common in the side of various faults in the inverter. The problem is mostly due to the following problems: first, as long as the speed converter is reported when starting, it is clear that the overcurrent is very serious, and most of them are load short circuits, mechanical parts stuck, inverters...

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 ...

Voltage vf and v difference: The two have different meanings, vf on the battery represents the feedback voltage, while v represents the capacity of the battery, which is the unit of measurement of voltage. Lithium battery is a kind of battery with lithium metal or lithium alloy as the positive/negative electrode data and the use of non-aqueous electrolyte solution. ...

Look at the quality of the surge protector, to see whether it can complete his basic specification, relative to the surge protector of the primary specification is whether the surge operating voltage can be constrained below the required value, the surge protector must discharge the lightning current when the mission is completed, this specification must be completely completed.

In the design of Delixi power distribution system, the selective cooperation between the upper and lower levels of the circuit breaker must have "selectivity, rapidity and sensitivity". Selectivity is related to the cooperation of the upper and lower circuit breakers, and the speed and sensitivity are related to the maintenance of the characteristics of the appliance itself and the way the line operates ...

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. Single-phase circuit single-phase power supply - power supply with a single AC electromotive force. The fundamental power supply method for civil electricity. Single-phase load – A load that is powered by a single-phase power supply. Household appliances such as lights, televisions, and electric fans are generally single-phase loads. The accounting method is as follows: a. When negative ...
