According to the scope of application, it can be divided into: outdoor cabinets, ...

A01--- Rittal cabinet control cabinet door opens View: Look at the door switches in the Rittal cabinet. Solution: (1) Adjust the position of the door switch. (2) Check whether the wiring method is correct (passive normally closed point at 1.2 points). A03 --- Filter Monitor ...

An introduction to Rittal switchgear The switch cabinet is a kind of electrical equipment, the outer line of the switch cabinet first enters the main control switch in the cabinet, and then enters the sub-control switch, and each branch is set according to its needs. Such as instrumentation, automatic control, motor magnetic switch, all kinds of AC contactors, etc., ...

What is a protective relay? Answer: It can reflect the failure or abnormal operation of electrical equipment in the power system, and act on the device that trips the switch or sends out a signal. What are the commonly used relays? A: Current Relay, Voltage Relay, Signal ...

What are the classifications of different electrical experiments according to their roles and requirements? A: It can be divided into insulation test and characteristic test. What are the factors that affect the degree of harm to the human body of electric shock? Answer: The magnitude of the current, the duration of the current, the path of the current, the resistance of the human body, and the ...

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: The cause of the fault can be judged according to the relay card drop, remote signaling information, etc. After the action of gas and temperature protection in the high-voltage cabinet ...

Industrial wires and cables include single-core wires and cables, rubber cables, shielded control cables, flame-retardant cables, fire-resistant cables, etc. Single-core wire and cable It means that there is only one conductor in the insulation layer, the common BV wire, and B represents the wiring; V stands for insulating polyvinyl chloride. Suitable for AC ...

1. Safety: As the carrier of electrical equipment, the outdoor cabinet must have excellent structural design, solid materials, and firm bottom fixation to meet the requirements of strong typhoons, strong rainstorms, and even strong earthquakes. At the same time, the cabinet should have anti-leakage, anti-short circuit, anti-cut and other requirements. 2. Rainproof and dustproof ...

One. The nature is different Distribution box: There is a large amount of parameter data in the distribution box. It generally constitutes a low-voltage distribution box. Control cabinet: The control cabinet is to assemble the switch cabinet, measuring instruments, protection devices and auxiliary equipment in a closed or semi-enclosed metal cabinet or screen according to the requirements of electrical wiring.

Server cabinets have requirements in terms of depth, height, and load-bearing capacity. There are three heights of 2.0 meters, 1.8 meters and 1.6 meters; The width is 800mm, 700mm or 600mm; There are three depths: 700mm, 800mm and 900mm. Can be configured: special fixed pallet, special ...

There are a total of 9 fault codes for Rittal cabinet air conditioners, They are: F1, F2, F3, FF, EH, EP, EL, SF, HC. Among them, F1, F2, and F3 represent improper use or failure of internal components; FF stands for Regulation Circuit Fault; EH stands for High Temperature Fault; E ...

1. Power failure: The power supply of the fan fails, such as the power cord is disconnected, the power plug is loose, etc., which will cause the current to fail to transmit normally, resulting in the fan stopping and rotating. 2. The temperature is too low: Some heat dissipation windbreakers have a temperature protection function, when the temperature is too low, the fan will automatically ...

First, set posts and responsibilities. The power department of distribution box equipment should number, register, file, hierarchical management, clear responsibilities, and regularly carry out technical inspection and maintenance of the distribution box.

In the high-voltage cabinet with the spring energy storage operating mechanism, the energy storage must be stored in advance before closing. The energy storage mechanism is driven by an electric motor and the gear mechanism lengthens the spring. There are two types of operation methods: electric and manual. Manual failure to store energy should be due to a mechanical failure of the mechanism. Manual energy storage ...

The probable cause is the phenomenon of the compressor protection device tripping. Compressor overload protection will trip, indicating that the system is too high-pressure, the pressure is too high, or the overheating current is too high. Causes and elimination of high pressure and overheating: 1. Too much refrigerant. Reduce the refrigeration dose appropriately. 2， ...

In the recent Winter Olympics, short track speed skating star Wang Meng helped lock the first gold medal of the Chinese team in the Winter Olympics in advance with "My eyes are rulers".
