Note:
1.TKQ5 family(two section, the isolation switch electrical equipment without the disconnection position)
2.TKQ5family(three section, the isolation switch electrical equipment the disconnection position)equipped with such functions as LCD dynamic display,overvoltage,undervoltage and open-phase protection).
| function trait： |
TKQ5 families of double power supply automatic switch and its
corresponding intellectual displayer ,which are mainly used in such sites as high-rise
building, post & communication, coal mines, vessels, military establishments,
industrial streamlines which need the uninterrupted power. Under the
inevitable trend of dramatic increasing demand for municipal power, they
can more satisfy the higher requirements for the power utilization reliability.
They are designed in a whole compact body, and the electrical-mechanical
interlocking ensures that the main backup power supplies cannot be closed
simultaneously. The position of both power supplies is in switch-off state
designed with the isolation function. The disjunction current is the instant
exciting mode.
Produce features：
◆Double-throw switch: Special arching chambers in the both sides isolated
from each other, short arching cutting time and the low consuming contacts.
◆Safe and reliable: Unique interlocking design and single action switch
ensuring only one end to power the system.
◆Small dimension and portable: The building block structure switch of
small dimension and weight saving the installation space and reducing
the costs.
◆OFF position:Manual or automatic operation can set the switch to be on
OFF position to facilitaet checking the failures and ensure and ensure the
safety.
