HYJL-12 High Voltage Metering Cabinet (box)

HYJL-12 high voltage metering cabinet (box) (hereinafter referred to as "floor
type metering box "), suitable for AC three-phase AC 50Hz, rated voltage 10kV
power system as a high voltage cable into the user's electric energy metering,
can be installed in parks, residential communities, industrial and mining areas
of the roadside lawn, can directly open the door to see the bottom of the meter
and local circuit breaker switching operation.
The floor type measuring box is mainly composed of vacuum circuit breaker, cast
type combined CT, lightning arrester, live display and intelligent control
device, etc. The measuring mode is three-phase three-phase system and three-
phase four-wire system, which can be configured with zero sequence current
transformer for grounding protection. The floor type metering box conforms to
GB/T 1984-2014 "High voltage AC Circuit breaker", DL/T 402-2016 "High voltage
AC Circuit breaker", DL/T 403-2000 "12kV~40.5kV High voltage vacuum circuit
breaker ordering technical conditions", GB/T 17201-2007 "Combined transformer"
and DL/T 721-2013 "Distribution automation system remote terminal" and other
technical standards.
