Delixi leakage protector tripping causes and solutions

Delixi control transformer use of the most types is BK, JBK, BKC and other types, these transformers use some precautions as follows: 1. Before purchasing, please estimate the total capacity of the electrical appliances you use.

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 ...

Delixi 3P air switch, rated current 630A, rated voltage 380V. The Icu=Ics=70kA of this circuit breaker. When the short-circuit current reaches 70kA, can the circuit breaker still be used? If it works, the ICU is already at its limit, which is a contradiction. If it can't be used, ICS is 70KA, which means ...

1. Cooling fan (2-3 years) As long as the inverter is in use, the cooling fan has always been running, so the cooling fan is generally a short-service life accessory, generally after the use of the cooling fan for 2-3 years, the bearings, balls, motors, etc. of the fan are seriously worn, and they need to be replaced.

In the project, because of the 630 A circuit breaker wiring bar in the 500 kVA box-type transformer, see the second circuit breaker and circuit breaker on the left in the figure. The temperature of this corresponding region is significantly higher than that of the other two corresponding regions, and the other two phases are also hot, and the copper bars of this phase have turned white. There is no induction Deli ...

Delixi Electric KGL1 latitude and longitude time control switch is suitable for communication 50Hz operating voltage 380V and the following control circuits, Delixi time control switch, according to the local latitude and longitude, according to the season to change the automatic adjustment control time, as the timing of the implementation of components. Plugging in or out of all sorts of ...

The advantages of linear DC regulator are high stability, small ripple, high reliability, and easy to make a multi-output connected adjustable power supply. The disadvantages are large size, bulkiness, and relatively low power. There are many kinds of this kind of regulated power supply, which can be divided into regulated power supply, stabilized current power supply and ...

The general leakage circuit breaker is wired using the principle of outgoing wire under the progressive line, only need to distinguish the phase line and the zero line, between, the zero line is marked with N on the right, and the incoming and outgoing lines are the same. Delixi DZ47LE C40 ...

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 ...

Read this statement carefully before installing, operating, maintaining, and viewing the EM60 series drives. In order to ensure the safety of your person, equipment and property, please be sure to read carefully before using our EM60 series inverter.

First, the principle of energy saving The die-casting machine is a typical periodic variable load equipment, and a complete production cycle includes the stages of mold clamping, injection, cooling, and mold opening and ejection. Usually the power of hydraulic equipment is supplied by a quantitative oil pump, and the motor that drives the oil pump to work has always been rated for its ...

Press the revoke function key first, then press and hold the school time function key, then adjust the time and date to the current moment, press the punctual function key again, adjust the time when the demand is closed and open to the specified value, if the demand is set to multiple groups, then press the punctual function key to set, without multiple groups ...

1. Classification of switch operation organization At present, the switches we encounter are generally divided into many types, such as oil-rich type (old model, now you can't see it at all), oil-poor type (some user stations also have it), SF6, vacuum, GIS (combined electrical appliances) and so on. These are all about the arc extinguishing medium of the switch. ...

At the end of July, Delixi Electric launched a new 6 series CDW6i structural circuit breaker and a number of industrial control accessories. The new 6 series CDW6i structural circuit breaker has complete product specifications, which can provide professional customers with more choices, excellent functions, and ...

1. Why does the maintenance function of the inverter operate when the clutch is connected to the load? When the load is connected with a clutch, at the moment of connection, the motor changes sharply from the no-load condition to the area with a large slip rate, and the large current flowing through causes the inverter to trip over the current and cannot work. ...

1. The closed-loop control of the stepper motor was first in the form of encoder For stepper motors with low split ratio, a slotted disc and photoelectric sensor are usually used as a reaction encoder assembly, and the number of notches is equal to the number of steps taken by the motor per revolution, · About high resolution ...

With the continuous progress of industrial automation, inverters have also been widely used, energy conservation and environmental protection as the center of China's industrial economic development, in the direction of the sustainable development of China's industry, but also in the effective promotion of the sustainable development of China's inverter profession, so that I ...

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. ...

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. How to disassemble the voltage regulator Generally, there are screws on the shell of the voltage regulator, please disconnect the power supply first, and then remove all the screws on both sides to take off the shell. After the regulator shell is disassembled, the circuit, copper coil, carbon brush, etc. inside will be revealed.
