Switchgear

Switchgear plays a very important role in the power system. Its working principle is to realize the switching and protection of the circuit channel through the coordination and interlocking of various switching devices. Among them, the high-voltage circuit breaker is the most critical equipment, which can use the spring mechanism to cut off the circuit when the current is overloaded or short-circuited to protect the safety of the entire power system.

XL-21 power cabinet

XL-21 power cabinet is widely used in power plants and industrial and mining enterprises, in three-phase AC 500V below three-phase three-wire, three-phase four-wire, three-phase five-wire and other power distribution systems for power or lighting distribution, indoor wall installation, screen front operation, screen front inspection and repair; The box is a fully enclosed structure, which is assembled by C profile or 8MF profile. The box adopts a new type of rotating load deviation off, can be operated with load, the front door is equipped with voltage, current indicator and signal lamp, button, switch and other main components. The distribution box adopts the new component designed by itself, which has the advantages of compact structure, beautiful appearance, easy maintenance, and a variety of connection schemes for users to choose.
A DC MCCB (Direct Current Molded Case Circuit Breaker) is a type of circuit breaker specifically designed to provide protection in DC electrical systems. It is used to interrupt current flow in the event of an overload, short circuit, or other electrical fault. DC MCCBs operate by using thermal-magnetic trip units to detect overcurrent conditions. When a fault is detected, the breaker trips, opening the circuit and stopping the flow of current to prevent damage to the electrical system.
MNS low voltage withdrawable type switchgear is used for conversion,distribution and control of electrical energy of power distribution equipment of AC 50~60Hz,400V.lt is mainly used in airports,power plants,substations,petrochemical plants,metallurgic plants,steel plants.transportation energy, light textile and residential districts,high-rise buildings,etc.The switchgear conforms to lEC439,GB/T7251.1 and other professional standard. lt uses standard module design,and it can respectively form standard unitssuchas protection,operation,conversion.control,regulation, determination and indication. Over 200 types of assembly parts can form frame structures of different schemes, and form fixed separation or drawer units. The users can select assemblies arbitrarily according their demands.
Miniature circuit breaker is mainly used for protection against overload and short circuit under the AC 50Hz/60Hz, reted voltage 230V/400V and rated current from 1A to 63A/125A. It also can be used for non-frequent on-and-off switch operation under normal circumstance.
A MCCB (Moulded Case Circuit Breaker) Enclosure serves as a robust and secure environment for MCBs, enhancing their functionality by providing additional safety features and ensuring reliable operation within the electrical infrastructure. It is engineered to withstand harsh conditions, thereby prolonging the life of the MCBs and safeguarding the entire electrical system from potential threats.
LV distribution board, is a concentration of measuring, qualification, reactive power compensation and other multi-functional comprehensive reach outdoor distribution equipment at an organic whole, with a short circuit, overload, over voltage, electric leakage protection function, small volume, beautiful appearance, economical and practical, installed on the outdoor column transformer pole, it is an ideal distribution of urban and rural power grid renovation of a new generation of products.
Product Summary The GGD low voltage switchgear is applied in power plant, substations.industry and mine corporations, etc., with rated voltage 400V, max operating current 4000A and rated frequency 50/60Hz. lt can be applied as power conversion distribution control, distribution and control of power, lighting and power distribution, etc.The cabinet structure of GGD type adopts the form of general cabinet, the frame is assembled by local welding of cold bending section steel, so it is firm and solid. The parts of the general cabinet are designed according to the principle of module, and have the installation hole with 20mm as the module, and the common coefficient is high. lt can make the factory realize the pre production, not only shortens the production cycle,but also improves the working efficiency.
GCS low Voltage withdrawable switchgear is suitable for the low voltage distribution system in power plant, petroleum industry, chemical industry metallurgy industry, spinning mill, high buildings, etc. lt is especially used in large power plant,petrochemical system and other locations which are required high automatic and computer interface. lt is serviced in the low voltage apparatus distribution devices of generator and power supply system distribution, motor central control and reactive power compensate of3 phase AC 50/60Hz,400V,rated current 4000A and lower.
