High-pressure side winding characteristic failures set explanation：
The transformer of actual use, its winding are emulation high voltage side of transformer windings by multiply winding and around being fabricated to one
And the transformer of simulation actual use is emulated, using three strands of windings and by the way of, the A phases in our above figures are
Example is described as follows：
Disconnected by Operation switch 1S~3S, may be configured as the failure mode of high pressure winding galvanic circle loose contact；
Explanation：Resistance RA is series at three strands of A phases and among winding loop, and when transformer is normal, RA is not present, only
When coupling part loose contact in loop, additional resistance RA will be generated in A phase windings loop, additional resistance RA's deposits
Just illustrating loose contact be present in loop, if contact is good, resistance RA both ends and the 1S connect switches need to only closed
On, by resistance RA short circuits, now RA resistance is zero, also means that the contact of A phase windings loop is good.（Remaining phase winding is identical）
Closed by Operation switch 4S~12S, may be configured as three kinds of failure sides of 1 strand, 2 strands, 3 bursts turn-to-turn short circuit of high pressure winding
Formula；
Explanation：Part winding both ends in sub-thread winding in A phases have simultaneously met 4S, and when 4S disconnects, it is normal to represent the winding
, when closing 4S, and the part winding connect is just not present, that is to say, that there occurs the situation of turn-to-turn short circuit for the part winding.
（Remaining phase winding is identical）
Disconnected by Operation switch 13S~21S, it is stranded to may be configured as high pressure winding（Each phase can be set disconnected 1 strand and break 2 strand two
Kind mode）, winding open circuit（Each phase winding is winding open circuit when setting disconnected 3 bursts）Failure mode；
Explanation：13S switches in sub-thread winding in A phases, are series in the sub-thread winding loop.When 13S is closed, representing should
Winding is normal, when disconnecting 4S, represents that the loop of sub-thread winding in A phases is disconnected, that is to say, that sub-thread in A phases around
There occurs the situation that winding is opened a way for group.（Remaining phase winding is identical）
By operating 22S~30S position, the failure mode of tap changer gear mistake shelves can be set；
Explanation：When sub-connecting switch of transformer is normal, when the shunting switch of high-pressure side winding is in " tap 1 "（Tap wire one）Position
When.22S, 25S, 28S are closed, and 23S, 24S, 26S, 27S, 29S, 30S disconnect." divide when the shunting switch of high-pressure side winding is in
Connect 2 "（Tap wire two）Position.23S, 26S, 29S are closed, and 22S, 24S, 25S, 27S, 28S, 30S disconnect.When high-pressure side winding
Shunting switch be in " tap 3 "（Tap wire three）During position.24S, 27S, 30S close, 22S, 23S, 25S, 26S, 28S,
29S disconnects.That is, when sub-connecting switch of transformer is normal, its tap position and its corresponding switch always correspond, when
Mean that shunting switch misplaces when not to corresponding to, that is to say, that there occurs the situation of wrong shelves.Such as：" tap 1 "（Tap wire
One）Should be 22S, 25S, 28S closure during position, when normal, 23S, 24S, 26S, 27S, 29S, 30S disconnect.If 23S,
25S, 28S are closed, and 22S, 24S, 26S, 27S, 29S, 30S disconnect.Just there occurs the " tap 1 " of A phase shunting switch（Tap wire
One）" tap 2 "（Tap wire two）Between wrong shelves.（Remaining phase winding is identical）
The foregoing is only a specific embodiment of the invention example, protection scope of the present invention are not limited thereto.Being familiar with should
Those skilled in the art the invention discloses technical scope in, change or replacement mode can be easily found, these all should
It is included within the scope of the present invention.Therefore, protection scope of the present invention should using the scope of the claims as
It is accurate.
