Description
Technical field
The utility model relates to a kind of ground structure that is used on the shunt reactor iron core.
Background technology
Along with the develop rapidly of power industry, people increase day by day to the demand of electric power, and high voltage, long distance power transmission are more and more general.Shunt reactor is an indispensable visual plant in superhigh pressure, the telecommunicate electric power transmission network.The countries in the world great majority all adopt shunt reactor to come the compensated line charging capacity at present, suppress the rising of light load line end voltage, and suppress switching overvoltage, play an important role to stablizing the transmission system safe operation.For the long distance power transmission system,, perhaps will make operation complicated as the running status that will be difficult to without shunt reactor to realize be scheduled to.Therefore reactor is safe and reliable, directly influences the safe operation of whole transmission line, and especially Tie Xin ground connection very easily causes local overheating if deal with improperly, will directly influence the safe operation of reactor.
Old ground structure is realized stationary positioned for the core clamping bottom is connected with the pad pin by the folder support plate, thisly be connected to insulation and connect, be with insulated tube by outside bolt is when assembling, make with insulating washer, insulation board between pad pin and the folder and insulate, prevent conducting between them.The core clamping bottom is connected with a pad pin earth connection with the pad pin, and core clamping top is drawn ground connection by an independent folder earth connection from the sleeve pipe on the fuel tank cap, and is shown in Figure 2 as Fig. 1.The shortcoming of this ground structure is insulated tube in case damage, the just possibility conducting of pad pin and folder support plate, and pad pin and folder are linking with an earth connection, so just form loop and produce circulation, easily cause local overheating, supplementary load loss increase, and oil chromatography is unusual, and this safe operation for reactor is very unfavorable.When having the scene of being exactly to do core clamping insulation against ground test again, can't find by the measurement of megohmmeter whether insulated tube damages between bottom pad pin and folder support plate, causes defective insulation, for safe operation hides some dangers for.
Summary of the invention
The purpose of this utility model provides a kind of novel grounded structure that is used on the shunt reactor iron core, can solve the existing the problems referred to above of old ground structure.
For reaching above purpose, the utility model takes following technical scheme to be achieved:
A kind of iron core grounding structure of shunt reactor, comprise core clamping, core clamping top is drawn ground connection by a folder earth connection from the sleeve pipe on the fuel tank cap, the core clamping bottom is provided with the folder support plate, this folder support plate be arranged on fuel tank at the bottom of and is connected with a pad pin of insulation at the bottom of the fuel tank, thisly be connected to insulation and connect, the pad pin is provided with and fills up the pin earth connection, it is characterized in that described pad pin earth connection is directly connected at the bottom of the fuel tank.
In the such scheme, described insulation connects by being arranged on an insulation board between pad pin and the folder support plate, realizes with a pad foot bolt that is with insulating washer and insulated tube outward again.
The advantage of the utility model ground structure is:
If 1 insulated tube is owing to reasons such as material own, manufacturing, transportation are damaged, cause pad pin and the conducting of folder support plate, but on pad pin earth connection is connected at the bottom of the fuel tank, can between pad pin and folder, not form the closed-loop path, can not produce circulation, cause local overheating, cause that oil chromatography is unusual, this improves the reactor unfailing performance greatly.
2, core clamping insulation against ground test is done at the scene, measure folder insulation against ground resistance with megohmmeter, if measured value is too small, just can not satisfy the requirement of product operations specification, just insulation is impaired between explanation pad pin and folder, insulated tube may be destroyed, and the core clamping insulation against ground has the property of monitoring, can prevent trouble before it happens.
3, this structure has stopped to form between pad pin and the folder possibility of closed-loop path, can not cause the supplementary load loss increase, and the heat ageing speed of having slowed down insulating part helps to prolong useful life of reactor.
Description of drawings
Fig. 1, Fig. 2 are the iron core grounding structure of existing a kind of shunt reactor.Wherein Fig. 2 is the A portion enlarged drawing among Fig. 1.
Among the figure: 1, fuel tank cap; 2, folder earth connection; 3, core clamping; 4, pad foot bolt; 5, insulating washer; 6, insulation board; 7, pad pin; 8 pad pin insulation; 9, pad pin earth connection; 10, at the bottom of the fuel tank; 11, insulated tube; 12, folder support plate.
Fig. 3, Fig. 4 are the iron core grounding structure of shunt reactor of the present utility model.Wherein Fig. 4 is the B portion enlarged drawing among Fig. 3.
Embodiment
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
As shown in Figure 3, Figure 4, a kind of iron core grounding structure of shunt reactor, comprise core clamping 3, core clamping top is drawn ground connection by a folder earth connection 2 from the sleeve pipe on the fuel tank cap 1, core clamping 3 bottoms are provided with two folder support plates 12, each folder support plate is connected with pad pin 7 usefulness pad foot bolts 4, fills up pin 7 and insulate and 8 be fixed at the bottom of the fuel tank on 10 by filling up pin.Folder support plate 12 be arranged on fuel tank at the bottom of pad pin 7 on 10 be connected to insulation and be connected, when promptly filling up foot bolt 4 and being linked and packed, its outer insulating washer 5 and insulated tube 11 of being with, an and insulation board 6 is set filling up between pin 7 and the folder support plate 12.Pad pin 7 is provided with pad pin earth connection 9, and this pad pin earth connection is directly connected at the bottom of the fuel tank on 10.
Ground structure of the present utility model solved the existing problem of old ground structure fully, and mode of connection is simple and convenient, and effect is obvious.
