Short-circuiting device assembled by loop terminals line.
A kind of multiple-head type electric control loop terminal line assembles short-circuiting device, including, short-circuit board (2), it is characterised in that: short
Fishplate bar (2) one end is provided with earth terminal (1), and the other end is provided with handle (4), is evenly distributed with several wiring on short-circuit board (2)
Nut (3), the short circuit wire loop (8) of shorting stub (9) one end is fixed on wiring nut (3) by screw locking, and the other end passes through
Ramp (10) has been fixedly clamped wiring handle (11), and one end of its wiring handle (11) is provided with and drawing that binding post head is connected
Line (12)；The connection ring (5) of earth lead (6) one end is locked with earth terminal (1) by bolt, and earth lead (6) other end sets
There is the ground loop (7) being connected with external ground device.
Described binding post head includes that (13), lug plate (14), wiring hook (15), connecting ring (16), semicircle are pitched in wiring
Binding post (17) and jointing clamp (18).
As required, selecting suitable binding post head, its binding post first end connecting lead wire (12), the other end accesses
In the terminal block of equipment secondary circuit terminal.
This utility model has simple in construction, reasonable in design, practical, because the lead-in wire of terminal line gathering short-circuiting device can basis
It is shorted the wiring type of terminal, has polymorphic type termination arbitrarily to change, it is ensured that shorting stub is more safe and reliable, this terminal line
Assemble short-circuiting device, easy to make, it is simple to carry, secondary terminals when being all kinds of power plant, the test of high voltage device of transformer station ac voltage withstanding
Son assembles the reliable method of short circuit grounding.
