Abstract
A kind of neutral point complexes of main transformer optimization of region arrangement, including three winding main transformer and neutral point complexes, the neutral point complexes include holder, arrester, disconnecting switch, discharging gap and ground wire, it is characterised in that：The arrester is arranged on holder, and arrester bottom end is connected with ground wire, and described discharging gap one end is connected to arrester top, and the other end is connected to by current transformer with ground wire；Described disconnecting switch one end is set to arrester top, and the other end is connected to ground wire, and the disconnecting switch is hollow operating lever, and the operating lever is the operating lever filled with liquid nitrogen.Using neutral point complexes provided by the utility model, tool arm length when without considering grounding switch separating brake, it not only saves occupation of land and reduces framework length, there is good economy, liquid nitrogen is added in operating lever, it can cause to be rapidly heated because of super-high-current in combined floodgate to avoid disconnecting switch, improve the safety of operation.
Description
Technical field
The utility model is related to a kind of neutral point complexes of main transformer optimization of region arrangement.
Background technology
For outdoor substation, when configuration complete using traditional neutral point, separate unit main transformer lateral dimension is generally 16.5
Rice, for the indoor station in city, 110kV is typically located at transformer oil pit both sides with 220kV neutral point complexes, in traditional
Property point complexes grounding switch it is as shown in Fig. 1, be in gate-dividing state when, tool arm deviate center about 750mm, installed in cloth
This size need to be considered to verify safety belt electrical distance when standby, therefore increases arrangement space.
Utility model content
To solve the above problems, providing a kind of main transformer optimization of region arrangement based on novel neutral point complexes, it is not necessarily to
Consider tool arm length when grounding switch separating brake.
The utility model uses following technical scheme：
A kind of main transformer optimization of region arrangement based on novel neutral point complexes, including three winding main transformer and neutrality
Point complexes, the neutral point complexes include holder, arrester, disconnecting switch, discharging gap and ground wire, described
Arrester be arranged on holder, arrester bottom end is connected with ground wire, and described discharging gap one end is connected to arrester top,
The other end is connected to by current transformer with ground wire；Described disconnecting switch one end is set to arrester top, the other end and ground
Line is connected to, and the disconnecting switch is hollow operating lever, and the operating lever is the operating lever filled with liquid nitrogen.
The arrester is the arrester of high-strength porcelain bushing.The beneficial effects of the utility model：
Using neutral point complexes provided by the utility model, tool arm length when without considering grounding switch separating brake, no
It only saves occupation of land and reduces framework length, have good economy, liquid nitrogen is added in operating lever, it can be to avoid isolation
Switch causes to be rapidly heated in combined floodgate because of super-high-current, improves the safety of operation.
Description of the drawings
Fig. 1 is prior art construction figure；
Fig. 2 is the utility model front view；
Fig. 3 is the utility model side view；
Wherein 1 is disconnecting switch, and 2 be discharging gap, and 3 be holder, and 4 be arrester, and 5 be current transformer.
Specific implementation mode
The utility model is described in further details below in conjunction with the drawings and specific embodiments.
A kind of main transformer optimization of region arrangement based on novel neutral point complexes, including three winding main transformer and neutrality
Point complexes, the neutral point complexes include holder 3, arrester 4, disconnecting switch 1, discharging gap 2 and ground wire,
The arrester 4 is arranged on holder, and 4 bottom end of arrester is connected with ground wire, 2 one end of the discharging gap and arrester 4
Top is connected to, and the other end is connected to by current transformer 5 with ground wire；Described 1 one end of disconnecting switch is set to arrester top,
The other end is connected to ground wire, and the disconnecting switch 1 is hollow operating lever, and the operating lever is the behaviour filled with liquid nitrogen
Make bar.
The arrester is the arrester of high-strength porcelain bushing.
Using neutral point complexes provided by the utility model, tool arm length when without considering grounding switch separating brake, no
It only saves occupation of land and reduces framework length, have good economy, liquid nitrogen is added in operating lever, it can be to avoid isolation
Switch causes to be rapidly heated in combined floodgate because of super-high-current, improves the safety of operation.
Above-described is only preferred embodiments of the present invention, it is noted that for those skilled in the art
For, under the premise of not departing from the utility model general idea, several changes and improvements can also be made, these should also be considered as
The scope of protection of the utility model.
