When the 12KV overhead distribution line T branch line or the end user fails, when the protection action
time limit of the inlet switch and the protection time limit of the substation outlet switch cannot be
reasonably adjusted, it will cause the substation outlet switch to trip.lf the fault is permanent in nature
and the substation coincidence will be unsuccessful,a local disturbance within the medium-voltage
user boundary will outage the entire 12KV distribution line. lf an outdoor demarcation circuit breaker is
installed at the T junction or the user end (responsibility demarcation point),and the fault (overcurrent,
short circuit, single-phase ground, etc.) is confirmed within the user boundary after judgment, the fault is
automatically isolated, which can ensure the normal power consumption of users in non-fault areas.The
application of ZW32-12F outdoor high-voltage intelligent demarcation vacuum circuit breaker (watchdog)
on 12KV feed overhead line can avoid the cascade power outage oftrouble-free lines,reduce the scope of
faulty power outages, shorten the power outage time of users, and protect the safe operation of the main
network. And with fault detection function, protection control function and communication function, it
can realize automatic cutting of single-phase ground fault and automatic isolation of short-circuit fault
between phases. The installation point is suitable for the dividing point of responsibility for the incoming
line of the 12KV distribution line user, and can also be applied to the branch line connection that
meets the requirements.

TAILI 38 Instrument transformer series LSY107-10 series current ransformer switch special transformer for outdoor column,the instalationis
fixed on the casing of the circuit breaker three-phase outdoor switch,can simultaneous achieve short
circuit protection,single groundini(zero) protection and provide power supply for the controller and
other functions.Can also be used in the ring network cabinet out of the three-phase casing,used as
a current measurement of electrical equipment,electrical energy measurement and microcomputer
protection.At present in the ZW20, ZW27, ZW28, VSP5 and other outdoor pole switch s widely used
to solve the problem of the internal space of the column switch can not install the zero sequence
The ron core and the two winding of the series transformer are made of hi quality epoxy resin vacuum
casting in the body of te fire retardant plastic casing,which can prevent moisture,stable performance
and no need of maintenance

The series of zero current transformers are used indoor. They are used for over driven
current protection in the electric non-useful-ground neutral system up to rated frequency 50Hz
or 60Hz and rated voltage 35KV. The type of the relay fitting with the transformers is DD-11/60、
DD-1/60.
The zero current transformers of LX K-Φ80~Φ240 series are casting into two half circles.
ln installation, the transformer can be clipped together.
