Rittal's new Maxi-PLS busbar system is launched!

We know that electronic and electrical equipment is installed in the electrical cabinet, in fact, there are working temperature requirements, the general storage temperature can not be lower than minus 25 degrees, the working temperature can not be lower than minus 20 degrees, but now the outdoor temperature in the north is very simple to reach the lower limit of this working temperature, this time heating ...

The power distribution panel is mainly composed of incoming cabinets, outgoing cabinets, capacitor cabinets, metering cabinets, etc. Incoming cabinet: also known as the receiving cabinet, is a device used to receive electrical energy from the power grid (from the incoming line to the busbar), generally installed with circuit breakers, CT, PT, isolation knives and other components. Outlet cabinet: ...

1. When the cables cross each other, the high-voltage cable should be below the low-voltage cable. If one of the cables is protected by a pipe or separated by a partition within 1m before and after the intersection, the minimum allowable distance is 0.25m. 2. When the cable is close to or crosses the thermal pipeline, if there are thermal insulation measures, the flat ...

What is Peak Load? What is trough load? What is Average Load? A: Peak load refers to the maximum load that can occur on the grid and the user in a day. The trough load is the hourly average of the least amount of usage that occurs in the grid and the users in a single day.

If the indoor temperature is higher than the outdoor one, or the indoor temperature is higher than the set temperature, the air conditioner will not start; Solution: Test the temperature comparison between indoor and outdoor to check whether the indoor temperature is too high. The voltage of the air conditioner is unstable, and the compressor cannot be started normally.

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 ...

Cabinet installation steps: 1. Before installing the cabinet, check whether the exhaust device of the cabinet is stable, whether the number of equipment support plates is complete, and whether the pulleys and support columns are stable. 2. The model, specification and device orientation of the cabinet should meet the planning requirements. 3. Cabinet ...

Power system: The wire and cable products used in the power system mainly include overhead bare wires, busbars (busbars), power cables (plastic cables, oil-paper power cables (basically replaced by plastic power cables), rubber cables, overhead insulated cables), branch cables, magnet wires and power equipment...

1. DC cable (1) Tandem cables between components. (2) Parallel cables between strings and between strings and DC distribution boxes (combiner boxes). (3) The cable between the DC distribution box and the inverter. The above cables are all DC cables, outdoor laying ...

1. Set the target temperature: the default temperature of the original factory is 35°C, you can press and hold the set button for more than 1 second after starting, the parameters start to flash, complete the temperature adjustment by pressing the UP and DOWN buttons, and after adjusting to the target temperature, press the set button to store the set parameters. 2. High temperature alarm: ...

1. The cabinet door is 25mm from the ground and 2.5mm thick mounting plate, and there are 20mm wide U-shaped curved edges on both sides, which makes the mounting plate stronger and easy to handle. 2. The three cable introduction cover plates at the bottom of the box can be replaced with each other, which is easy to move, easy to import cables, and easy to open holes into the line. 3 ...

Display parameters: The control panel can display various parameters of the inverter, such as input/output voltage, current, frequency, speed, etc. Parameter setting: The control panel can set various parameters of the inverter, such as operating mode, frequency range, acceleration time, deceleration time, etc. ...

Why use transformers to measure high voltage and high currents? Answer: (1) Expand the scope of use of the instrument. As long as the transformer with different transformer ratios and converter ratios is used in conjunction with a voltmeter with a full voltage of 100V and an ammeter with a full current of 5A, it will be ...

The handover ceremony of the customized outdoor cabinet of the integrated pumping station jointly developed by Rittal and Shu Pengshi was held in Rittal (China) Company. Mr. Tian Ming, General Manager of Shupenshi Environmental Technology (Changzhou) Co., Ltd., and Mr. Xue Boliang, Technical Director, attended the handover ceremony with technical engineers. Power...

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 ...

First of all, the number of the control cable often starts with the letter "C", which indicates that the control cable is specially designed to connect different sensors and control devices as a medium for signal transmission. This cable can transmit data signals and has a certain resistance to wear and chemical corrosion, so ...

What are the main differences between electronic control equipment and power distribution equipment products? Answer: The function of electronic control equipment is mainly control, and the function of power distribution equipment is mainly transmission. How much is the external design of domestic electronic control equipment products? Answer: Control panel, control cabinet, control box and console ...

What is Phase Order? Answer: It is the order of the phases, which is the sequence in which the instantaneous value of alternating current changes from negative to positive through zero What is the safety distance of the human body grounding point when a grounding fault occurs in high-voltage equipment? A: Indoor should be larger than 4 m, outdoor should be larger than 8 ...

▲ GGD AC low-voltage distribution cabinet: (1) Use GGD type AC low-voltage distribution cabinet is suitable for substations, power plants, factories and mining enterprises and other power users AC 50Hz, rated working voltage 380V, rated working current 1000-3150A distribution system, as a power ...
