Materials to be prepared when consulting high and low voltage switchgear and reactive power compensation devices.
In order to better serve customers and meet their various needs, we often encounter some problems when consulting the prices of high and low voltage switchgear, distribution cabinets, and reactive power compensation. So, what information do we need to provide when consulting the prices of high and low voltage switchgear?
1、 When inquiring about the price of high and low voltage switchgear, the first thing to do is to inform the switchgear manufacturer of the model, rated voltage, rated current, etc. of the switchgear being consulted. Secondly, provide a system diagram, distribution room layout plan, and switchgear arrangement and configuration diagram, etc., so as to more accurately quote the most favorable price. The polysilicon ingot casting furnace is the key equipment for polysilicon manufacturing in the complete set of power equipment. The stability of its process flow, the stability and progressiveness of equipment control are directly related to whether qualified silicon ingots can be produced, and the qualified silicon ingots directly determine the photoelectric conversion efficiency of cells made of silicon chips. In the absence of drawings, the electrical department can also provide drawings and quotations for customers to design solutions according to their requirements, but customers must inform them of the voltage level, maximum current, name of the powered equipment, and quantity of powered equipment of the switchgear.
2、 When consulting about reactive power compensation devices, customers only need to provide the voltage level, compensation capacity, and whether reactive power compensation needs to be switched in steps. The capacitor switching device for landscape type buried substations can be composed of controllable silicon load switches or capacitor specific switching contactors. Thyristors are contactless switching devices, and when the voltage points at both ends are zero (equipotential), they are connected to the filtering branch. Cut off the filtering branch when the current crosses zero. During the switching process, there is no transient impact on the power grid and no surge impact when closing.
Why provide these materials?
Because with these materials, electrical technicians can develop and design products such as switchgear and reactive power compensation devices according to customer requirements, and more accurately meet customer requirements. The complete set of power distribution equipment is supplied by the manufacturing plant and assembled into a power distribution device after being transported to the site. It divides the main electrical circuit into several units, each unit is a circuit, and the circuit breakers, knife switches, current transformers, voltage transformers, as well as protection, control, measurement and other equipment of each unit are assembled in a whole cabinet. The power device composed of multiple high-voltage switchgear installed in power plants, substations or distribution stations is called a complete distribution device. To play a role in energy conservation and protection for customers in the power generation, transmission and distribution, energy conversion, and control of energy consuming equipment in the power system.
