Product Description

I.Description This series low-voltage Switchgear is a factory assembly combine switchgear which is used standard module; its technique has been reach the 90s international advanced level This series low-voltage withdrawabl switchgear can apply in power plant ,Substation ,petroleum and chemical Industry; metallurgy and steel rolling ,traffic and energy ,light industry and other corporation, and it is also can used in residence area and high-rise building. This switchgear used for energy transfer, distribution and control of electrical system distribution equipment of AC 50/60HZ,rated service voltage 660V and below   II.Service condition 1. Ambient temperature: -5'C~+40'C. Average temperature in 24 hours <= 35'C. 2. Altitude: <=2000m. 3. Air humidity at 40'C <=50%. Higher humidity at lower temperature is permitted. Occasional condensation due to temperature variation should be considered. 4. No excessive vibration. 5. No corrosion to electric elements. Special condition subject to users.   III.TECHNICAL DATA (1)     Rated insulation voltage  660V (2)     Rated operating voltage  660V (3)     Rated current of main busbar up to 5500A (4)     Rated shot-time withstand current of busbar(1S) up to 100KA-1600A (5)     Rated peak withstand current of busbars up to 250KA (6)     Operating current of distribution busbars(vertical busbars) up to 90-176KA (7)     Degree of protection:IP30/IP40   IV.Features and Benefits 1.YMNS(MNS) switchgear assembles 4, 2 or 1 drawer units in the space of 8E height, or 1 unit in 16E or 24E. GCS switchgear drawers are divided into 1/2, 1, 2, 3 units 2.Breaker compartment doors have no ventilation openings, thus protecting operators from hot ionized gases vented by the breaker during circuit interruption. 3.A superior bus system offers different levels of protection.  Insulated and isolated bus makes maintenance procedures touch friendly to reduce the risk of arc flash. 4.True closed-door drawout construction is standard with all GCS, YMNS(MNS) equipment. The breaker compartment doors remain stationary and closed while the breaker is racked out from the connect position, through test, to the disconnect position. Doors are secured with rugged 1/4-turn latches. 5.An easy-to-read metal instrument panel above each Circuit Breaker holds a variety of control circuit devices, including the RELT switch. 6.Each circuit breaker is located in a completely enclosed ventilated compartment with grounded steel barriers to minimize the possibility of fault communication between compartments. 7.Optional safety shutters protect operators from accidental contact with live conductors when the breaker is withdrawn. 8.Easy access to equipment compartments simplifies maintenance of the breaker cubicle and control circuit elements as well as inspection of the bolted bus connections. 9.A rail-mounted hoist on top of the switchgear provides the means for installing and removing breakers from the equipment. This is a standard feature on NEMA 3R outdoor walk-in construction and optional on indoor construction. 10.Control wires run between compartments in steel riser channels. Customer terminal blocks are located in metal-enclosed wire troughs in the rear cable area. Intercubicle wiring is run in a wireway on top of the switchgear, where interconnection terminal blocks are located. 11.All circuit breakers are equipped with rollers and a guidebar to provide easy and accurate drawout operation. 12.An optional remote racking device reduces the risk of the arc flash hazard by allowing the operator or electrician to move the breaker anywhere between the DISCONNECT and CONNECT positions from outside the arc flash boundary. 13.Optional infrared (IR) scanning windows can be installed in the switchgear rear covers to facilitate the use of IR cameras for thermally scanning cable terminations. 14.GCS, YMNS(MNS) switchgear can be expanded easily to handle increased loading and system changes. Specify a requirement for a fully equipped future breaker to obtain a cubicle that has been set up for additional breaker installation, or add vertical sections without modifications or the use of transition sections. 15.An array of safety interlock and padlocking features are available to accommodate any type of lockout-tagout procedure a customer may have. 16.Optional Power Management:  With the proper devices, facility power can be tracked and controlled.   We are always at service,welcome to consult us anytime!
