30 34 Switching apparatus AC Structure: The disconnector has monopolar, two-column horizontally rotating structure. The busbar (placed on the post insulators) consists of two sets of connectors- left and right, cooperating with each other. The terminals and central contacts are made of electrolytic copper covered with silver. Contact this design uses the additional influence of electrodynamic forces generated during the flow of short-circuit, causing additional pressure. Supply conduits are mounted to rotary terminals. The connection the conductors to the disconnector is provided by M12 bolts. The basis of the disconnector is made of rigid frame, welded of steel sections. To the basis two bearing bodies are mounted and post insulators are bolted to that bodies. Regulating pins, mounted at the base of insulators provide smooth angle compensation. In the upper part of the rotary body are placed flat levers, which (with strings and crank shaft) makes transmission, providing simultaneous rotation of insulators of 90⁰. Grounding blade is fixed to the lever mechanism providing the possibility of rotary and plane motion. In the first stage, grounding blade is rotated to the vertical, and then is pushed into the permanent contact, which is located in the busbar. Copper connection connects lower end of the grounding blade to the basis of the disconnector.

34 38 Switching apparatus AC RW - 3-pole indoor cut-off switch Construction and operation: RW-type cut-off switches are three-pole devices with secant movement of blade of current path. The apparatus have modular design. You can easily equip a basic version of the earthing switch (top or bottom). The fixed contacts are made of copper flat and covered with a layer of silver. High technical parameters are the result of the applied solution of the main path coupled with arcing contact. Opening and closing the arcing contacts is delayed compared to the main contacts (movable). During the shutdown process, arc quenching occurs at the arcing contact. Quenching occurs due to the compressed air outlet, through a nozzle (automatically when opening) connected by rapid streching of the arc. The speed of opening and closing the switch is independent of the speed of operation. There are two diffrent mechanism- for opening and closing. The reinforcement of mechanisms occur by motor or manual drive, then both mechanisms are being reinforcemented in the same time, while closing. RW cut-off switches can be driven by motor NS -EL or NR- 1 manual drive. Advantages: modular design the possibility of building the drives of plane and rotory motion of the string the possibility of choosing the side of mounting the drive (left-right) cooperation with motor drive NS-EL and manual drive NR-1 reliability high technical parameters possibility of equipping the switch with reactance insulators 12; 17,5; 24 kv, electromagnetic release 24; 48; 110; 220 V AC/DC, auxiliary contacts showing the position of the device Application: Indoor cut-off switches RW type and a set of safety breakers RW type are used in indoor switchgears of 7,2-24 kv. They are designed to switch on and off the currents that do not exceed their rated DC current. Cut-off switches equipped with safety breakers RWB -type can switch off rated currents by cooperating with fuse switch disconnector. In the open state device creates the isolating clearance in air, thus meeting the requirements of the cut-off switches.

42 46 Switching apparatus - components NRWO-4 - indoor rotary hand Advantages: simple design easy to coulpe with the disconnector high durability and reliability signaling of device status drive a large selection of equipment (electromagnetic blockades and signal connectors) Construction and operation: NR-3 type drive is designed for opening and closing the cut-off switches, disconnectors, earthing switches and various other indoor devices. The voltage up to 36 kv. Manual drive type NRWO-4 is articulated quadrilateral in crank-rocker system. It consits of hand lever, the string bent into a curve, double lever welded to the shaft (on one end of the shaft there is the knurl), and two walls (between them is placed the entire kinematics). At the end of the lever is a handle. On the side wall there is the sleeve of the locks mounting The circuit switch is mounted on the bracket (on the upper edges of the side walls) and is coupled to the drive s shaft by the mechanism that adjusts the movable contacts.

43 Switching apparatus - components L1 47 SPS - high current contact for DC switching apparatus The contacts are used for current conduction (intensity 630 up to 6300 A). They are also used when constructing the switchgears, trams, trolleybuses, trains etc. Silver plated they create strong connector. There is a possibility to create the product for the specific needs.

44 48 Switching apparatus - components A3 A2 A1 PB-1 - fuse switch disconnector Application: Fuse switch disconnector with fuse insert is designed for protecting against short circuits of transformators and capacitor s batteries. The main purpose is the protection of distributive devices against the dynamic and heat action of high short circuit currents by limiting the peak current and cutting the power supply in few milliseconds. Advantages: simple design small size easy to mount ability to use typical fuse-links Operating: Fuse switch disconnectors are made of electroinsulating plate. The contacts clips are mounted to the plate and they provide mounting the fuse-link. The contact clip consist of three elements: compression spring, contact spring and the terminal.

45 Switching apparatus - components 49 LP-1- auxiliary contact Application: Auxiliary contacts type LP-1 are designed to work with indoor disconnectors, cut-off switches and earthing switches of medium voltage distribution network. The use of auxiliary contacts allows to obtain the information about the status of indoor device. The contacts can be used to send a clear signal about the state of the position of apparatus for automation systems. They can also be used to any kind of blockades in switchgears. Standard number of the auxiliary contacts is 16 (8NZ 8 NO). Advantages: simple design standard contacts small size the ability to adjust the angle of operation the ability to determine different combinations of switching contacts Technical parameters: rated insulation voltage 500 V rated DC current 6 A switching durability operating temperature -5 do 50 C operating position any level of protection IP 20 Connectors are available in various configurations: LP-1 8-4NC+4NO LP NC+6NO LP NC+8NO LP NC+10NO Zakład Zakład Produkcji Aparatury Elektrycznej i Izolatorów i ELTOM ELTOM Tomasz Tomasz Cisak Cisak ul.
