Product DescriptionKYN61-40.5 air-insulated metal-clad
withdrawable switchgear (hereinafter as switchgear is a kind
of HV switchgear.It is designed as a withdrawable module type
panel, and the withdrawable part is fitted with
VD4-36E,VD4-36 withdrawable vacuum circuit breaker
manufactured by Boerstn Electric Company . It can also be fitted
with isolation truck, PT truck, fuses truck and so on. It is
applicable to three phase AC 50/60 Hz power system,and mainly.
Boerstn Electric co. design and make this withdrawable switchgear
under the standard of IEC62271-200.etcKYN61-40.5 armored removable
AC metal-enclosed switchgear (hereinafter referred to as
switchgear) is used with a three-phase AC 50/60HZ, voltage 40.5kv
power system, used to receive and distribute electrical energy and
control, protect and monitor the circuit .Intelligent technology is
mainly reflected in the following aspects:1. Adopt an intelligent
switch cabinet operating system (1) The
circuit breaker of the switch cabinet enters, exits, opens and
closes to realize remote control or local electric operation.
(2) The grounding switch of the switch cabinet
is opened and closed to realize remote control or local electric
operation. (3) All primary contact parts
in the switch cabinet adopt visual interface and temperature
measurement methods to ensure the safe connection of all
contacts.2.Adopt intelligent information processing system to
diagnose and monitor the failure precursor of the switchgear
body (1) On-line detection and over-limit monitoring of
busbar and cabinet temperature. (2) On-line monitoring
of operating characteristics of circuit breaker opening and closing
speed. (3) Online monitoring of the mechanical
performance of the operating mechanism. (4) Online
detection and alarm of insulation level.3. Intelligent
anti-misoperation operating system(1) Prompts and previews of
various operations. (2) Check the operation and lockout of
misoperation.(3) Prohibit operation prompts and operating condition
prompts.4. Intelligent function of secondary circuitIntelligent
measurement, signal, protection, control and movement.5.
Remembrance of grid failureWave recording, login, simulation replay
and fault recording, provide analysis data.Product
