Abstract
The utility model discloses a side-mounted fixed metal sealing switch device which consists of a main bus and an upper disconnecting switch arranged in a bus room, a vacuum circuit breaker and a current transformer arranged in a circuit breaker room, a lower disconnecting switch, an overvoltage protector, a ground bus and a relay room switch arranged in a cable room, and a miniature bus in a miniature bus room, wherein an operating mechanism is arranged on the panel of the circuit breaker chamber. The side-mounted fixed metal sealing switch device is characterized in that the vacuum circuit breaker, the upper disconnecting switch and the lower disconnecting switch are all in side-mounted fixing manner, and the A, B and C phases of the vacuum circuit breaker are consistent to the A, B and C phases of the main bus in arrangement direction, and are all arranged from front to back and from far to near. The side-mounted fixed metal sealing switch device has the characteristics of being compact compared with a formal fixing manner and a handcart manner, small in equipment appearance size, and small in occupied space.
Description
Technical field
The utility model belongs to power transmission and distribution industry technical field of electrical equipment, especially relates to a kind of side and adorns fixed metal enclosed switch device.
Technical background
10KV air insulation metal enclosed switchgear divides handcart-type and fixed two kinds, the present fixed formal dress that mostly is, be that circuit breaker three-phase A, B, C from left to right arrange, arrange before and after main bus bar three-phase A, B, the C,, form the intersection situation from as far as closely, can realize needed function like this, but equipment volume is bigger, and it is very big to take up room, and installs restricted.
Summary of the invention
The purpose of this utility model is to improve the deficiency of prior art and provides a kind of, take up room little side littler than the fixed and handcart-type compactness of formal dress, contour size of the unit(s) to adorn fixed metal enclosed switch device.
The purpose of this utility model is to realize like this; a kind of side is adorned fixed metal enclosed switch device; be by the main bus bar that is installed in the bus-bar room; last isolating switch; be installed in the vacuum circuit-breaker in the breaker chamber; current transformer; be installed in the following isolating switch in the cable vault; overvoltage protection device; earth bus; relay bungalow; little bus in the little bus-bar room is formed; operating mechanism is contained on the breaker chamber panel; be characterized in vacuum circuit-breaker; last isolating switch and following isolating switch are side and adorn fixed; the A of vacuum circuit-breaker; B; the A of C three-phase and main bus bar; B; C three-phase orientation unanimity, and before and after being from as far as nearly arrangement.
Compared with the prior art the utility model has following distinguishing feature and good effect: the utility model vacuum circuit-breaker, last isolating switch and following isolating switch are side and adorn fixed, the A of vacuum circuit-breaker, B, the A of C three-phase and main bus bar, B, C three-phase orientation unanimity, and before and after being from as far as nearly arrangement, branch bus and main bus bar A have been avoided like this, B, C three situation that intersects, out-phase is intersected the insulation distance requirement, homophase does not have, this switching device element is consistent with main bus bar phase sequence direction, there is not the phase insulation required distance that will guarantee element and the different phase sequences of main bus bar, element is installed compacter like this, connecting line is shorter, switchgear overall dimension is dwindled a lot, satisfying under the same technical parameter situation, it is fixed all littler with handcart-type overall dimension than formal dress that side is adorned fixed switchgear overall dimension, is a kind of compact switchgear, economical with materials, particularly copper bar quantity reduces, thereby reduces cost; It is little to the utlity model has volume, the characteristics of in light weight, good looking appearance.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described in further details.
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is the A-A cutaway view of Fig. 1.
Embodiment
Embodiment; a kind of side is adorned fixed metal enclosed switch device; with reference to Fig. 1; Fig. 2; be that main bus bar 1 is installed in bus-bar room; last isolating switch 2; vacuum circuit-breaker 3 is installed in the breaker chamber; current transformer 4; isolating switch 5 down is installed in the cable vault; overvoltage protection device 6 and earth bus 9; vacuum circuit-breaker 3; last isolating switch 2 and following isolating switch 5 are side and adorn fixed; the A of vacuum circuit-breaker 3; B; the A of C three-phase and main bus bar 1; B; C three-phase orientation unanimity; and before and after being from as far as nearly arrangement; connection between each element all can connect according to prior art as required; main bus bar 1 is connected with last isolating switch 2 upper ends in the present embodiment; last isolating switch 2 lower ends are connected with current transformer 4 ends of incoming cables; current transformer 4 leading-out terminals are connected with vacuum circuit-breaker 3 upper ends; vacuum circuit-breaker 3 lower ends are connected with following isolating switch 5 upper ends; connecting between the element all is to connect by copper bar; service cable is connected with following isolating switch 5 lower ends; the current supply circuit of forming the switching device electric energy transmitting like this; secondary component in the relay bungalow is connected with the auxiliary contact of electric elements; the control loop of forming switching device; little bus 8 in the little bus-bar room provides power supply to control loop; overvoltage protection device 6 is connected on the primary circuit; for whole device provides overvoltage protection; earth bus 9 is that all earth connections are pooled on the earth bus; play the ground protection effect; operating mechanism 7 is contained on the breaker chamber panel; the structure of operating mechanism 7 is same as the prior art, and this constitutes a kind of structure of the present utility model.
