2 DRIESCHER 2 kv Switchgears in compliance with EN General, Operating conditions, Technical standards Technical data, Description of the switch panels Overview of switch panel variants W 2 0, W 2 2 and 02 Panel variants W 2 0 Panel variants W 2 2 and W Insulating protective barrier, Auxiliary equipment, Weights Production program General The metalencapsulated, airinsulated mediumvoltage switchgears, Type W 2 are for universal application: They range from compact ring cable switchgears up to complex power distribution switchgears. Tailored to meet the needs of public utility networks and power supply companies in industry and municipal buildings. These mediumvoltage switchgears meet the user's specific requirements in full and ensure a satisfactory power distribution. The W 2 standard panel types are available in three different dimensional sizes:. W 2 0; W x D x H: 00 x 0 x 00 mm. 2. W 2 2; W x D x H: 0 x 0 x 200 mm.. W 2 02; W x D x H: 00 x 0 x 200 mm. They are available as individual panels or as a combined switchgear, where the equipment, panel sequence etc. can be determined by the customer. Operating Conditions The switch panels of Type W 2 are installed in closed electrical operating areas which are only to be entered by skilled personnel and appropriately instructed persons. The equipment can be used at an altitude of up to 000 m above sea level. For installations above an altitude of 000 m the rated insulating level of the switchgear must be corrected accordingly. The switch panels are designed for use under normal operating conditions in compliance with the standard EN 22. Technical Standards The design of the airinsulated switch panels corresponds to the specifications of the EN The resistance to accidental arcs of the switch panels has been determined at ka and 20 ka; s, by and independent testing institute. The installed switchgear equipment is designed in compliance with EN 22. The degree of protection of the switch panels corresponds to IP X. Technical data on the installed switchgear equipment are available for Switchdisconnector H 22 in list 22 Earthing and disconnecting switches in list Circuit breakers V... in list 2

The switch panel frame is made of a screwed, hotgalvanized composite structure. The front of the switch panels has a singlewing door of steel sheet with door hinge optionally on the right or left. A window of compound glass is inserted in the door. The cover in front of the bus bar compartment is either screwed on or designed as a door for the relay box positioned behind it. Each switch panel has a screwed on rear panel of galvanized sheet metal. Connecting cables are conducted into the switch panels from below and are mounted on cross rails which can be adjusted in two dimensions. The doors and covers of the switchgear are painted in structural paint (available in different colours according to the customer's request). Equipment The switch panels of Type W 2 are available in the following versions: Cable switch panel Type WK 2 Transformer feeder panel Type WT 2 Measuring switch panel Type WM 2 Bus sectionalizer panel Type WÜ 2 Circuitbreaker panel Type WL 2 All switch panels are partitioned off from panel to panel, in the busbar area, by means of fibrousglass reinforced plastic plates with leadin openings. Pressure relief can be in upward or downward direction. Switch panels equipped with loadbreak switches can optionally be fitted with an earthing switch as well. Integrated in the circuitbreaker panel, Type WL 2, there is also a bus disconnector. It is also possible to equip these panels with a set of current transformers and voltage transformers as well as with an earthing switch. The optional interlocking of the equipment practically rules out any form of incorrect operation. All builtin switchgear equipment can be operated manually or via motoroperated mechanisms when the panel door is closed. The product program is completed by special measuring panels which are fitted with current and voltage transformers. Earthing switches or spherical fixed points are available for earthing and shortcircuiting. An insulating protective barrier can be inserted when the panel door is closed. It is possible to install appropriate surge voltage protectors in the panel, if required. All switch panels are designed with central locking and doublebit key. There are additional locking features available in the form of profile cylinders or padlocks, if required.
