Construction of Vapromatic Type Liquid Rotor Resistance Starter :- The LRS (V) is a rectangular tank having electrolyte in it and works on the principle of resistance cutting based on different resistivity of electrolyte at different temperatures. The tank will be constructed from heavy gauge sheet steel and have enclosure protection of IP-42. The electrodes will be of zinc passivated M.S. suitably supported with insulator and bushings to sustain stress at the time of external faults. The fixed electrodes are mounted at the bottom of the tank and adjustable electrodes will be mounted at the top of the electrolyte tank through insulating bushing. The inside surface of the electrolyte tank will be painted with anticorrosive epoxy paint. Polypropylene phase barriers will be provided to prevent circulating current between the electrodes. Also the metallic resistance used for bringing the motor from 80% speed to rated speed would be mounted in a separate chamber which would be able to dissipate the generated heat. The tank will have accessories e.g. drain valve with brass plug at the bottom, separate plug for filling of electrolyte etc. Painting will be done by Hand Spray Gun M/cs with approved paint shade.
Main supply will be of 415 Volts and control supply for LRS (V) will be 230 or 110Volts and accordingly contactor coils would be of 230 or 110Volts only. Initial position and full speed position indicating contactors each having 2NO and 2NC potential free contacts will be provided for sequence interlocking. Electrolyte level and temperature sensor with alarm and trip contacts will be provided for sequence interlocking.
The LRS (V) will be complete with ample sized cable box and will be suitable for termination of PVC/XLPE Aluminum conductor cable. The terminal box will have detachable gland plate.
Control Panel having Switch-gear Components as :-
Interlocking for LRS (V) :
The Potential Free Contacts are required for Interlocks with:
Indications (with LED type Lamps :
Terminal Blocks : All LRS (V) units will be provided with separate Terminal Blocks for termination of wires for External Connections.
Inspection and Testing : All routine tests and temperature rise tests as per relevant British Standards & IS.
It will be having MS Electrolyte tank, floor mounting, free standing type, dust & vermin proof construction. It will be provided Fixed & Moving electrodes made-out by MS Sheet Steel having horizontal movement, Anti-corrosive Epoxy black paint (inside the electrolyte tank walls), Phase barriers of polypropylene, Mechanism box, Power/Shorting Contactor/Cable Box and all other accessories for motorized as well as manually operation. Integral Control Box of suitable size (housed with main MS tank of LRS) will be provided & it having RDOL Starter of suitable rating Aux. contactor for reversing & forwarding Pilot motor & Moving electrodes, Over load relay, Key actuated Auto/Manual selector switch, Push button, Isolating switch, Indicating lamps, Power/Control TBs & necessary back-up protection etc. It will have Interlocking arrangement/circuit for Stator control panel, so that, Main motor can not be started unless resistance is in fully ‘IN’ Position. It will be provided AC3 duty Air Break Power contactor of ‘Reputed make’ (in delta connected) to suit the RA of motor for final short-circuiting the resistance when motor attains full speed. It will have provision for Manual operation, also.
