Description

The MSO (Motorized Switch Operator) provides remote control of disconnect switches and load break switches at substations and in transmission and distribution networks. According to the manufacturer, the operator meets or exceeds ANSI requirements for SCADA systems. The MSO can work standalone with local control or be equipped with communication hardware, including an RTU, a modem, a radio, an antenna, cables and measuring insulators with sensors for current, voltage and fault detection.

The MSOD has a reciprocating output and works with 15–35 kV distribution disconnect switches. The MSOT is intended for 46–72.5 kV transmission disconnect switches. The operator consists of interchangeable control and communication modules, so upgrades are carried out on a test bench in the workshop rather than on the pole. The basic pushbutton unit can later be fitted with various SCADA systems, and a new module with the required remote control functions is tested on the bench and quickly installed in the field. According to the manufacturer, the MSO has been used in intelligent networks for over 15 years, giving operators remote control and data on current, voltage and faults in order to locate a fault and restore power.

The mechanism and cabinet comply with G.O. 95. The NEMA 3R cabinet is made of 14 gauge stainless steel or gray painted steel to ANSI 71. All linkage elements are made of colored corrosion-resistant materials and are insulated from the electronics. The unit has a motor and output shaft clutch for manual operation, position indication in motor and manual operation, a motor cut-off lock and a physical stop in a lockable clamp to verify the break point. Trip and interlock lamps and a trip handle are also provided. Operating time is 0.5–1.0 s.

Power supply is 120 V AC / 12 V DC, with a 200 W power supply with surge protection and a thermostatically controlled 150 W heater. Backup is provided by a 12 V 55 Ah AGM battery and a 16 V 58 F supercapacitor. There is a 12 and 24 V DC source for communication equipment. The weight is under 225 lb. The operator is supplied adjusted and ready for installation, with a mounting lug.
