Three-Phase Electronic Oil Insulated Reclosers
WE, WVE, VWE, and VWVE
Kyle® W-group electronically controlled, three-phase automatic circuit reclosers provide reliable, economical overcurrent protection for distribution circuits rated through 38 kV.
Recloser operations are programmed on the electronic control panel with accurate, preset tripping characteristics and reclosing times. Operating programs are precise and unvaried, enabling closer coordination with other protective devices on the system. When system requirements change, program settings are easily altered.
The Kyle reclosers in the W-group offer a broad selection of ratings to fit varied system needs. Recloser and control accessories enable further tailoring of the protective program to achieve maximum system operating flexibility.
- Types WE or VWE reclosers provide three-phase protection on systems rated 2.4 through 14.4.
- Types WVE27 or VWVE27 can be applied on systems rated through 24.9 kV.
- Types WVE38X and VWVE38X reclosers provide higher-voltage system protection (24.9 through 34.5 kV).
Sensing current transformers, mounted in the recloser, supply fault-sensing information to the electronic control. Tripping and closing signals from the control energize the operating circuits in the recloser. Due to a single CT ratio for all ratings, minimum-trip values of the electronic control are independent of the continuous-current and interrupting ratings of the recloser. Flexibility in coordination with other protective devices is provided by dual time-current characteristics from a choice of available curves, minimum trip values, reclosing and resetting time settings, and a selection of accessories.
Contact-closing energy is provided by a closing solenoid that also stores energy in the trip mechanism. Low-voltage closing solenoids can be employed, but auxiliary voltage must then be supplied to the recloser.
- Types WE, WVE27, and WVE38X reclosers use oil as the arc interrupting medium. Movable bridge-type contacts provide two breaks in series on each phase. Separate self-generating interrupter chambers at each of the two breaks provide for effective interruption of all currents, from minimum load to rated maximum fault.
- Types VWE, VWVE27, and VWVE38X are vacuum-interrupted. A single break on each phase is accomplished by separating contacts inside the vacuum interrupter. All arcing is contained within the vacuum envelope.
