Abstract
The utility model discloses double gas chamber gas insulated metal sealed switch equipment, which comprises a breaker chamber, and a cable chamber and a bus chamber which are respectively in circuit connection with the breaker chamber; the breaker chamber, the cable chamber and the bus chamber form a supply and distribution loop; the breaker chamber and the bus chamber are gas chambers which are separated with each other; the bus chamber is arranged on the lower part of the breaker chamber; the breaker chamber and the bus chamber are communicated up and down through a gas chamber connecting device; the bus chamber is provided with a position switch; and the position switch is communicated with the breaker chamber. In the equipment, the bus chamber is arranged on the lower part, thereby having more convenience for the construction in the cable chamber and the maintenance of the breaker chamber, and improving the operation reliability of the switch equipment; even if the breaker chamber needs to be replaced integrally because of faults, the normal operation of the bus chamber can not be affected, and the need of continuous power supply of the switch equipment is ensured.
Description
Technical field
The utility model relates to a kind of gas-insulated metal enclosed switch equipment, is a kind of pair of air chamber gas-insulated metal enclosed switch equipment specifically.
Background technology
In present 12KV～40.5KV three-phase ac power system, gas-insulated metal enclosed switch equipment is many based on two air chambers arrangement up and down, its structure be above successively in bus-bar room, breaker chamber, the cable vault of setting down.Bus-bar room and breaker chamber are filled with the low pressure gas as dielectric, and 2 air chambers connects by wearing the cabinet bushing insulator, and the cable vault is connected the whole switch cubicle of support as the base form with breaker chamber.Because this structure places the top with bus-bar room, make that connector strengthens from the cumulative departure that the basic plane distance is installed between bus, be difficult to guarantee bus and the precision that connects, make corresponding with it electric insulation level seem weak.In addition, in case just need stop energising when operating breaker chamber is wanted integral replacing fully, separately could change the permutation switch cubicle, not satisfy the continuity requirement of switchgear power supply, and repair also ten minutes trouble the breaker chamber of certain switch cubicle; The cable vault places whole below then to make the installing space deficiency, so that strengthened in the cable vault such as difficulty of construction such as cable end grafting.Therefore, present gas-insulated metal enclosed switch device structure still awaits further improvement.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of reliability height is provided, power supply continuity good two air chamber gas-insulated metal enclosed switch equipment.
Goal of the invention of the present utility model is achieved in that a kind of pair of air chamber gas-insulated metal enclosed switch equipment, comprise breaker chamber, the cable vault and the bus-bar room that are connected with the breaker chamber circuit respectively, breaker chamber, cable vault and bus-bar room constitute for joining the loop, it is characterized in that: described breaker chamber and bus-bar room are separate air chamber, and bus-bar room is located at the breaker chamber below.
Described breaker chamber and bus-bar room are communicated with up and down by the air chamber jockey.
Be provided with position switch in the described bus-bar room, this position switch is communicated with breaker chamber.
Described position switch is a three position switch.
The utility model improves the gas-insulated metal enclosed switch equipment of arrangement about existing two air chambers.Breaker chamber and bus-bar room are two separate chambers, and bus-bar room is arranged at the below of breaker chamber, by the air chamber jockey breaker chamber and bus-bar room are communicated with up and down.Of the present utility model pair of air chamber gas-insulated metal enclosed switch equipment, switchgear is with the bus-bar room underlying, promptly strengthened the height of circuit breaker plenum chamber, thereby made the maintenance of construction in the cable vault and breaker chamber convenient, the easier needs that satisfy various Main Wire Connection Scheme; Connector is reduced from basic plane distance and deviation are installed, improved bus and connect precision, guaranteed corresponding electric insulation level, improve the switchgear reliability of operation; When wanting integral replacing, can not influence the normal operation of bus-bar room, guarantee the continuity requirement of switchgear power supply even breaker chamber hinders for some reason.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model most preferred embodiment.
Embodiment
The utility model will be further described below in conjunction with accompanying drawing.
According to shown in Figure 1, of the present utility model pair of air chamber gas-insulated metal enclosed switch equipment, mainly comprise breaker chamber 1, the cable vault 2 and the bus-bar room 3 that are connected with breaker chamber 1 circuit, in addition also comprise low voltage control chamber 4, pressure relief channels 5 in the switchgear.Wherein breaker chamber 1, cable vault 2 and bus-bar room 3 constitute for joining the loop.Breaker chamber 1 and bus-bar room 3 are two separate plenum chambers, and bus-bar room 3 is positioned at the below of breaker chamber 1.Circuit breaker 6 and cable socket 7 wherein are housed in the breaker chamber 1, position switch 8 and bus expansion interface 9 are housed in the bus-bar room 3, this position switch 8 is a three position switch.Breaker chamber 1 and bus-bar room 3 are communicated with up and down by air chamber jockey 10.By the underlying of bus-bar room 3, cable vault 2 can support breaker chamber 1 and bus-bar room 3 simultaneously.Low voltage control chamber 4 and pressure relief channels 5 and breaker chamber 1, bus-bar room 3 and cable vault 2 are connected by bolted.Cable in the cable vault 2 cooperates with the cable socket 7 of breaker chamber 1, and the circuit breaker 6 that is linked in sequence, three position switch 8, bus expansion interface 9 common formations are once for joining the loop.Breaker chamber 1 and bus-bar room 3 are two independently air chambers, to the maintenance of breaker chamber 1, only need that the position switch 8 in the bus-bar room 3 is operated the isolation station and get final product; And guarantee that position switch 8 is under isolation station state, under fault, change breaker chamber 1, only need breaker chamber 1 separated with bus-bar room 3 from air chamber jockey 10 and get final product, do not influence the state of bus-bar room 3, guarantee the connection of bus expansion interface 9, satisfied the continuity power reguirements of switchgear.
