Description
Technical field
The utility model belongs to technical field of electric equipment, especially relates to a kind of high voltage bus extension system.
Background technology
In high voltage supply system, as gas-insulated high-voltage switch cabinet obtains in city net power supply, field of track traffic
More and more extensive application, the in-site installation of gas-insulated high-voltage switch cabinet, later maintenance are increasingly taken seriously.
At present, the extended mode arranged side by side of conventional gas-insulated high-voltage switch cabinet mainly has two kinds, and the first uses cable
Annex and cable are installed at the top of switch cubicle, realize that switch cubicle extends side by side, and this method is disadvantageous in that：Cable scene
Difficulty is made, mounting process is complicated, needs professional to make, stress is excessive, and difficulty of processing is beaten；By the swollen shrinkage of air heat and cable
The influence of the factors such as manufactured size deviation, easily occur stress concentration phenomenon between cable accessory and cable, buried for operation steady in a long-term
Lower potential safety hazard；The ability such as exposed operation, anti-high and low-temp, humidity, smog is relatively poor for a long time for cable accessory；Because cable typically carries
Maximum flow is no more than 630A, so this expansion structure, typically has certain application in rated current 630A and following system,
But for rated current 2000A and the bus-bar system of the above, if using this organization plan, switch cubicle scheme will become very multiple
It is miscellaneous；Cost of manufacture is of a relatively high.
Second of application bus casing is installed in switch cubicle side, realizes that switch cubicle extends side by side, the deficiency of this mode
Part is：After switch cabinet air box inflation, influenceed by factors such as the swollen shrinkages of air heat, housing is easily deformed, but switch cubicle spacing
It has been fixed that, therefore connect stress and concentrate at bus casing, the safe operation to switch cubicle is unfavorable；If intermediate switch cabinet goes out
Existing failure, changes difficulty, that is, needs to change after the switch cubicle of breakdown switch cabinet side is all removed.But in practical application
In, switch cubicle is applied in outdoor switching station or switchyard, safeguards that space is small, and during replacing, operation is difficult, especially for larger
Type switch cubicle, this operating method for solving failure will be more difficult.
Both the above existing method to switch cubicle be extended Shi Junyou each the shortcomings that, therefore among prior art urgently
A kind of new technical scheme is needed to solve this problem.
Utility model content
Technical problem to be solved in the utility model is：A kind of longitudinal female type high voltage bus system extending transversely is provided
System, it can be applied in rated current 2000A and the above bus-bar system, and the extension of Convenient switch cabinet, also allow for daily
Maintenance, moreover it is possible to allow bus casing and expanding plug do not expanded with heat and contract with cold by gas tank and influenceed.
A kind of longitudinal female type high voltage bus system extending transversely, it is characterized in that：Including bus gas tank, switch cabinet air box,
First bus casing group, expanding plug, the second bus casing group, copper bar and bolt；
The bus gas tank is sealing structure, and inside is full of insulating gas；
The switch cabinet air box is closed structure, and inside is full of insulating gas；
The bus gas tank is fixedly connected by bolt with the switch cabinet air box；
The first bus casing group is placed in the inside of the bus gas tank；
The second bus casing group is placed in the inside of the switch cabinet air box；
The first bus casing group includes three bus casings, and every bus casing is internally provided with bus；
The second bus casing group includes three bus casings, and every bus casing is internally provided with bus；
One end of the expanding plug is connected by the closed perforate of the bus gas tank with the first bus casing group,
The other end is connected by the closed perforate of the switch cabinet air box with the second bus casing group；
Bus in the first bus casing group is fixedly connected with the copper bar.
The bus gas tank is secured by bolts in the top or bottom of the switch cabinet air box.
By above-mentioned design, the utility model can bring following beneficial effect：It can realize switch cubicle laterally simultaneously
Row arrangement, and realize that female type is connected between bus-bar system, connection is reliable, while the replacing and maintenance of Convenient switch cabinet；If gas
Case deforms because of hot rolling shrinkage, big stress variation will not be caused to bus casing and expanding plug；Anti-high and low-temp, humidity,
The abilities such as smog are strong；Structure is simplified, advantage of lower cost.
