Scada-Mate CX™ Switching Systems

Features

• Integral stored-energy operating mechanism. Circuit making and circuit breaking are accomplished within sealed interrupters, in a controlled SF6 environment.  In addition to electrically operating the interrupters, the operating mechanism provides non-electrical mechanical opening and closing of the interrupters by means of a manual-operation pull ring
• Open/closed indicator on the side of the base shows interrupter position.
• Lockout/Tagout.  The switch can be locked open to prevent electrical or manual closing.
• Optional Hookstick Disconnect.  Visible air-gap isolation of switched-open circuits — needed only when work on the feeder is required — can be provided by an optional integral, hookstick-operated disconnect.
• Permanent lifting bracket is provided for convenient rigging and hoisting…making Scada-Mate CX Switches easy to install.
• Voltage and Current Sensing. Scada-Mate CX Switches can be furnished with factory-installed three-phase S&C Current Sensors, or three-phase S&C Current/Voltage Sensors on one or both sides of the switch. Alternately, S&C sensors or sensors of other manufacture can be added later. With their integral sensors and disconnect — and no vertical operating pipe — Scada-Mate CX Switches present a clean uncluttered look.

And Scada-Mate CX Switches are expandable to meet your DA needs. Just purchase the features required today . . . you can easily upgrade tomorrow with the wide variety of switch controls available.

Options

A variety of optional features are available for Scada-Mate CX Switching Systems to meet your specific needs:

Visible-Break Disconnect

If your system practices require it, Scada-Mate CX upright mounting configurations can be furnished with an integral disconnect.

Manual Hookstick Operating Mechanism

The manually operated Scada-Mate CX uses the same sealed interrupters and enclosed one-piece base as Scada-Mate CX Switches. They provide the same three-pole group operation and ratings as Scada-Mate CX Switches: 900 amperes continuous and interrupting at 14.4 and 25 kV, with a five-time duty-cycle fault-closing rating of 20,000 amperes, RMS, asymmetrical.

With just one pull of a hookstick, circuit making/circuit breaking is performed inside the sealed interrupters, in a controlled sulfur hexafluoride (SF6) environment. The interrupting performance with the spring-loaded mechanism is independent of the speed of the operator. Interrupter position is clearly visible on the open/closed indicator on the side of the base.

It is possible to replace the manual operator with an automated stored-energy operator to convert the switch for automation applications with the IntelliTeam^® SG Automatic Restoration System. The conversion also requires adding any required sensors to the switch along with cable to the control.

Mounting Styles

Scada-Mate CX Switches are available in three mounting configurations: upright, upright compact (alley arm), and tiered-outboard, accommodating the most widely used over-head-distribution line configurations. Switches in the upright mounting configuration are also available with extra mounting-pole clearance.

Switch Controls and Operators

6800 Series Automatic Switch Controls

6800 Series Automatic Switch Controls combine sophisticated automatic control schemes with RTU functionality, data logging, and advanced communication capabilities in one integrated package. Models are available for overhead distribution applications that can automate one, two, or three pole-mounted or pedestal-mounted switches or fault-interrupting devices. Models are also available for underground distribution applications in pad-mounted gear that can likewise automate one, two, or three switches or fault-interrupting devices.

The 6801 Automatic Switch Controls features:

• Automatic sectionalizing based on factors such as overcurrent, loss of voltage, or phase unbalance
• Data logging, including overcurrent faults and daily high/low values
• Stand-alone or SCADA operation
• Support for a wide variety of communication hardware and software protocols
• Sophisticated power supply/battery system
• Compatible with the IntelliTeam^® SG Automatic Restoration System
• Easy-to-use IntelliLink® Setup Software

Communication and Control Units

S&C Communication and Control Units are custom-engineered controls specifically designed for use with Scada-Mate CX™ Switches and Scada-Mate® Switches. They accommodate most user-specified remote terminal units and communication devices, and are generally used in distribution automation and other Smart Grid applications that don’t involve the IntelliTeam^® SG Automatic Restoration System.

S&C Communication and Control Units have been extensively tested to ensure reliable operation in the harshest environments. Two versions are available. Communication and Control Unit—Self-Powered features a temperature-compensated constant-voltage battery charger that’s powered by an S&C Voltage Sensor. Communication and Control Unit—Externally Powered features a high-output, temperature-compensated, constant-voltage battery charger with a unique battery management system that’s powered by a user-supplied 120-Vac source.

Both versions include the following features as standard:

• Switch control with open/close push buttons, switch-position indicating lamps, disconnect closed-and-latched indicating lamp, local/remote switch, and operation counter.
• Integral load-disconnect circuitry that prevents deep discharge of batteries on loss of ac source, plus alarms for loss of ac source, battery low voltage, or charger overvoltage. The battery-load test feature works in conjunction with suitably equipped RTUs.
• Rechargeable sealed-lead starved-electrolyte battery packs.
• Rugged 316L stainless-steel enclosure.
