Description
Technical field
The utility model relates to a kind of power supplying and distributing equipment, relates in particular to a kind of high-tension switch cabinet.
Background technology
The layout basic structure of the indoor high-tension room of traction substation of present domestic electric railway is: switch cubicle directly adopts gridiron structure, circuit breaker advances by the ground track that is laid in and releases operation, isolating switch and insulator are installed in transformer station's interior wall, connect busbar in the system and arrange by supporting insulator is exposed along body of wall.The result of this common-mode is, indoor isolating switch and circuit breaker are to be arranged in the net grid, and degree of protection is low, and the equipment repair and maintenance workload is big; Bus row interlaced arrangement causes whole high-tension room mixed and disorderly on body of wall, and just baked wheaten cake joint operation of accident occurs, brings disaster to whole transformer station; The track of circuit breaker is the transformer station ground that is laid in separately, causes the debugging work that cooperates between track and the circuit breaker dolly very complicated uncontrollable, and contact resistance is increased, and buries accident potential; The operating handle of isolating switch is installed on the more weak net grid of holding power, and debugging work load is also very many, even, in the Installation and Debugging process, often cause the damage of equipment.Because switch cubicle simple and easy, cause the complexity of debugging work, the increase of operation and maintenance cost, failure rate such as increases at situation; Along with the demand of epoch to electric railway stability, design a kind of install simple, debugging is easy, easy to maintenance, stable performance, safe and reliable metal armouring closed switch cabinet are very important.
The utility model content
Technique effect of the present utility model can overcome above-mentioned defective, and a kind of armored withdraw type high-tension switch cabinet is provided, and its degree of protection height, structural strength is big, Installation and Debugging are convenient.
For achieving the above object, the utility model adopts following technical scheme: it comprises cabinet, is packaged with breaker chamber, control room, main bus bar chamber, outlet bus-bar room, bypass isolate bus chamber in the cabinet, adopts the metal partion (metp) sealing to separate between each chamber; Set gradually breaker chamber, main bus bar chamber, outlet bus-bar room, bypass isolate bus chamber to the rear end by front end in the cabinet, the control room is positioned at breaker chamber and is arranged on cabinet foremost; The upper side of cabinet is provided with the little bus-bar room of secondary, the little bus-bar room of secondary be positioned at the control room directly over.
Be provided with circuit breaker cart in the breaker chamber, circuit breaker cart is arranged on the guide rail of breaker chamber bottom and can slides along guide rail.Such design has realized moving on the circuit breaker cart built on stilts, and place bottom of cabinet bulk to have on the guide rail of certain altitude and strength support, it no longer is that console mode is installed that meaning is being hidden circuit breaker, and contact of breaker cooperates on the switch cabinet body that relies on the may command machining accuracy fully with contact box.
The indoor isolating switch that is provided with of bypass isolate bus, isolating switch adopt the wall-penetrating type isolating switch or adopt wall bushing to cooperate the isolating switch mode.On the bypass isolating switch dividing plate that is installed between bypass isolate bus chamber and the outlet bus-bar room through walls, outlet bus-bar room and bypass isolate bus chamber are kept apart fully, circuit breaker also is connected by contact box with the outlet bus-bar room in addition, mean like this: open other touched compartment (breaker chamber and bypass isolate bus chamber) of switch cubicle, the outlet bus-bar room of switch cubicle and bypass isolate bus chamber still can be charged; The bypass isolation can be adopted the wall-penetrating type isolating switch or adopt isolating switch to add the isolation that the wall bushing mode realizes the outlet bus-bar room; Degree of protection is the highest ranking LSC2B level of metal enclosed switchgear and control appliance.
Breaker chamber, main bus bar chamber, outlet bus-bar room and bypass isolate bus chamber all are provided with the arcing passage, the front door of switch cabinet structural strength strengthens in addition, be provided with the labyrinth type pressure release passage, the cabinet door has structurally increased reinforcement, guarantees switch cubicle does not jeopardize operating personnel when inner arcing fault safety when having reduced the distortion of cabinet door; Fixedly install current transformer on the circuit breaker cart in addition, make things convenient for the maintenance of current transformer.
The relative existing equipment of the present invention has following advantage:
(1) switch cubicle is safe and reliable to operation, and the all-metal hermetically-sealed construction of switch cubicle makes pollution such as dust and biology be difficult for entering power distribution equipment, and the switch cubicle operation is more stable, and line service significantly reduces;
(2) switch cubicle is stable, and switch cubicle is divided into the compartment at complete interval, separates with metallic plate fully between the compartment, and the arcing passage is set, and has limited the expansion of accident in the switch cubicle; Switch cubicle designs for metallic seal, has prevented the expansion of fault, has ensured the normal operation of other switch cubicle.
(3) switch cubicle intensity height, cell structure intensity originally is low, this switch cubicle underframe adopts the high strength design, reduces switch cubicle distortion under external force, and has guaranteed the accurate contraposition of circuit breaker, door-plate high strength design protection operator's safety before the cabinet.
(4) switch cubicle is easy for installation, switch cubicle has been realized batch production, suitability for industrialized production, main switch cubicle installment work is all finished in factory, levelness to basic terrace during installation requires to relax, the orthogonal rake of cabinet was no more than the critical conditions of 5% grade when the equipment of not imposing was installed, and the simple construction in switch cubicle back in place gets final product, and has reduced the construction of on-the-spot very complicated, improve the efficient of engineering construction, reduced the Installation and Debugging expense.
