1. Normal power transmission operation process of low-voltage distribution cabinet: 1. All load switches are disconnected, confirm that the switches have at least one breakpoint; 2. Confirm that the power switch is in the disconnected position; 3. Send the power supply to the operation circuit, and the status indication is normal; 4. The incoming switch is - isolated ...

Opening faults can also be divided into mechanical faults and electrical faults. Electrical faults mainly include open control loops, coil faults, auxiliary switch faults, etc. 1. Fault phenomenon: when the red light is not on, the electric cannot be opened, which is the fault of the auxiliary switch. When the opening coil burns out, there is smoke, odor, insurance ...

1. In principle, the power cord and network cable of the cabinet should be sorted out separately; 2. The placement of the equipment should be appropriate, avoid squeezing each other, avoid being too high or too low, and avoid being too close to each other; 3. If there are too many devices in the cabinet, the equipment should be numbered; 4. For each line ...

1. Judgment and treatment of sudden tripping fault of high-voltage switchgear during operation 1) Fault phenomenon: The cause of this failure is the protection action. The high-voltage cabinet is equipped with protection against overcurrent, quick cut-off, gas and temperature. 2) Judgment method: judging the cause of the fault can be based on the relay off, remote ...

Power distribution circuits? Answer: From the regional substation to the substation of the electricity unit or the power supply line of the city and township, it is the line used to distribute electric energy. Power lines can be divided into according to the erection method? A: Overhead power lines and cable lines. ...

What is eddy current? What are the harms of eddy currents? Answer: When an alternating current is passed through a wire, an alternating magnetic field is created around the wire. An induced current is generated inside the whole conductor in an alternating magnetic field, and because this induced current forms a closed loop inside the whole conductor, ...

Ri4Power satisfies four specifications of the system Rittal Ri4Power has developed this concept as a complete system solution for the safe and fast installation of low-voltage switchgear for machines, systems and buildings. Rittal Ri4Power It is a device that covers high-current power distribution ...

Usage code - not marked as power cable, K- (control cable), P- (signal cable); Conductor material code - not marked as copper (can also be marked as CU), L- (aluminum); Inner Sheath Code – Q-(Lead Packed), L- (Aluminum Cladding), H- (Rubber Jacket), V-(Polyvinyl Chloride ...

Wide air volume range: 20-900m3/h Innovative diagonal flow fan and brushless DC EC motor technology for higher air flow and uniform distribution of cold air Comes with an interface module for controlling and monitoring fans The standard degree of protection is IP54, up to IP56 with a water spray cover ...

1. Rittal cabinet can be divided into three series from the structure, ES cabinet (five-fold profile cabinet), PS cabinet (nine-fold profile cabinet), TS cabinet (sixteen-fold profile cabinet), the biggest feature is that the Rittal cabinet is the selection of profile structure structure, the structure of the cabinet is welded first, and then the top plate, bottom plate, side panel, door...

1. Site selection. The location of the low-voltage distribution room should be close to the load center, set up in a place with less dust, less corrosive medium, dry and slight vibration, and should appropriately leave room for development; Second, the layout of power distribution equipment. The layout of the distribution equipment in the low-voltage distribution room must follow the principle of safety, safety, and safety.

1. Tie the cable tie at the beginning of the root of the cable with a cable tie, if there are too many cables, the number of the network cable is divided into two or many parts from the center, but the demand ensures that each part of the network cable is connected, because the next step is simple. 2. According to ...

1. Filter maintenance of the indoor unit: The filter screen of the indoor unit generally needs to be replaced once every two months. It is not recommended to continue to use it after rinsing, because the rinsed filter is easy to stick, so that ventilation and ventilation are not smooth, and air circulation is affected. So if it's a one-off, direct replacement, not ...

How is an electric current formed? Answer: The free electrons in the conductor move regularly and directionally under the action of the electric field force, and an electric current is formed. What are the indicators of power quality? Answer: Voltage deviation, voltage fluctuation and flicker, voltage sine wave distortion rate, frequency deviation. ...
