Do you know the drawer type switchgear ? In fact, there are not many brands of drawer type switchgear. Today we are going to understand the Rittal switchgear. I believe that the brand is still relatively unfamiliar to the brand, so I will introduce you to us today. At the same time, the switchgear can let everyone know more about the brand of Rittal. At the same time, it can also have more understanding of the electrical equipment of the switchgear. The following is a small series of decoration homes to let everyone know about it.
Weitu Electric (Beijing) Co., Ltd. is located in the development zone of Shunyi District, Beijing. It is a high-tech enterprise with a registered capital of 50 million yuan for the development and production of intensive busway. The derivative products include cable trays and distribution box control cabinets. The production scale is large and the production cycle is short. The company has 120 employees, including 35 technicians. Rittal Electric is the first company in North China to launch a closed busway. The intensive busway and fire-resistant busway produced by the state have reached the domestic leading level.
Drawer type switchgear - Introduction of Rittal switchgear
The switch cabinet is an electrical device. The external line of the switch cabinet first enters the main control switch in the cabinet, and then enters the sub-control switch. Each branch is set according to its needs. Such as instrumentation, automatic control, motor magnetic switch, various AC contactors, etc., some also have high-voltage room and low-voltage room switchgear, with high-voltage busbars, such as power plants, and some also have low-cycle to protect the main equipment. Load reduction.
Drawer type switchgear - Rittal switchgear classification
Classified by voltage level
According to the voltage class, AC1000V and below are usually referred to as low-voltage switchgear (such as PGL, GGD, GCK, GBD, MNS, etc.), and AC1000V or higher is called high-voltage switchgear (such as GG-1A, XGN15, KYN48, etc.), and sometimes The voltage in the high voltage cabinet is AC10kV, which is called medium voltage cabinet (such as XGN15 type 10kV ring network cabinet).
Classified by voltage waveform
Divided into: AC switchgear, DC switchgear.
Classified by internal structure
Withdrawable switchgear (such as GCS, GCK, MNS, etc.), fixed switchgear (such as GGD, etc.)
Classified by purpose
Incoming cabinets, outlet cabinets, metering cabinets, compensation cabinets (capacitor cabinets), corner cabinets, busbar cabinets.
Drawer type switch cabinet difference
1, GCS type low voltage switchgear
GCS type low-voltage switchgears are generally equipped with clear three-stage position. GCS type drawer type switchgear has a big disadvantage. Its structure is made, especially the assembly is troublesome. Most of them are bolted, and the drawer is divided into 1/2 unit. 5 units of 1 unit, 1.5 unit, 2 unit and 3 unit, up to 3 PC cabinets, up to 22 drawer circuits in MCC cabinet, E=20mm and 100mm in the main cabinet, 160mm in drawer height The busbar is flat on the back, and there are outlet passages on the upper and lower sides of the cable room. The panel has obvious signs of separation, combination, test and extraction position.
2, GCK type low voltage switchgear
GCK low-voltage switchgear has high breaking capacity, good dynamic thermal stability, and advanced and reasonable structure. The electrical scheme of GCK drawer type switchgear is flexible, series, versatile, any combination of various scheme units, and one cabinet. The utility model has the advantages of large number of circuits, saving floor space, high protection level, safety and reliability, convenient maintenance, etc. The drawer is divided into 1/2 unit, 1 unit, 2 units and 3 units, and can hold up to 9 units and cabinets. The body can hold 18 units. The drawer has the joint, minute, test and extraction positions, which can ensure normal work, and can safely repair the components in the drawer. From the drawer's propulsion mode, it is basically divided into single plug-in type, double-plug type, and rock-in type. . Most drawer units do not have a clear 3 break position, only basic interlocking can be achieved. Most of them have no experimental position. The main frame is installed with a module hole E=25mm, and the GCK drawer type switch cabinet has a height of 1800mm. The functional units occupy a separate compartment, and the drawer layer is 200mm high. However, with the development of the electrical industry, the size of the circuit breaker is getting smaller and smaller, and it can be installed horizontally.
3, MNS type low voltage switchgear
MNS type low-voltage switchgear structure is a combination type, MNS type drawer type switchgear is divided into standard type and non-standard type. All structural parts of the frame are galvanized or galvanized sheet, imported aluminum-zinc plate folding molding material. The modulus hole E=25mm, through various joints, self-tapping locking screws and 8.8-level hex bolts, the frame structure can be assembled without special tools, and the partition inside the cabinet adopts segmented multi-function isolation board to make PC The cabinet and the MCC cabinet are mixed. The drawer height is 200mm, which can be divided into 8E/4, 8E/2, 8E, 16E, 24E. The effective height of the MCC cabinet is 72E, and up to 36 outlet circuits can be installed. Cabinet exterior size (width × depth × height): 600 (800, 1000) × 800 (600, 1000) × 2200, unit: mm.
The introduction of the drawer type switchgear is here. The above is the introduction of the Rittal switchgear. The Rittal switchgear is used as a power conversion tool for functions such as power generation, power transmission and distribution, not only in practical functions. Many aspects play a very important role in ensuring the stability of our daily electricity consumption and reducing the possibility of danger. In general, even if we do not use the Rittal switchgear, we still need to understand. If you want to know more information, please continue to pay attention to the decoration home network.
