Abstract
The utility model discloses a switch device with an alternating-current high-voltage metal sealed ring net. The switch device is characterized in that a shell is internally provided with a three-phase load switch; a cabinet is internally provided with a baffle which is provided with three insulating sleeves for connection of a three-phase cable and a cable connector; three wiring terminals of the three-phase load switch are respectively and correspondingly connected with the three insulating sleeves by copper bars in a one-to-one manner. According to the switch device with the alternating-current high-voltage metal sealed ring net, the space of the device can be effectively saved, and better electrical insulating performance and safety performance can be achieved.
Description
Technical field
The utility model belongs to the electric power project engineering field, relates to the metal enclosed looped network switch apparatus of a kind of ac high-voltage.
Background technology
Along with the continuous development of urban construction, cable power supply becomes the main flow in city, and the tap processing of cable and the requirement of laying of ring network power supply system are also more and more higher.The metal enclosed looped network switch apparatus of existing ac high-voltage is of a great variety, but passes through thermal shrinkage type terminal or cold-shrink type terminal more than the connection of cable greatly.Still there is certain defective in this class processing mode because of the bonding conductor of cable exposes in air.Thereby more and more occasion utilizes separable connector replacement cables terminal that cable is handled, and the equal insulated body of all energized conductors of the separable connector of this class is closed, and is not subjected to the influence of external environment.But the three-phase of the looped network equipment of such separable connector of adapted is all identical with separable connector three-phase direction in the market, certainly will increase cable taking the space like this.Therefore, be necessary the looped network equipment of existing separable connector is improved.
The utility model content
Technical problem to be solved in the utility model is to propose the metal enclosed looped network switch apparatus of a kind of ac high-voltage, and the metal enclosed looped network switch apparatus of this ac high-voltage can effectively be saved the device space, and has better electrical insulation properties and security performance.
Technical solution of the present utility model is as follows:
The metal enclosed looped network switch apparatus of a kind of ac high-voltage is equipped with the three-phase load switch in the housing, be provided with dividing plate in the cabinet, and dividing plate is provided with three insulating sleeves and is used for connecting of threephase cable and cable connector; Three terminals of three-phase load switch are respectively by copper bar and three corresponding one by one joining of insulative.
The three-phase load switch is the sulphur hexafluoride on-load switch.
Cable connector is separable connector.
Cabinet is provided with the Xiamen, cabinet door in also being provided with in the cabinet.
Interior cabinet door is provided with the visual window that is used to observe equipment in the cabinet.
Beneficial effect:
The metal enclosed looped network switch apparatus of this novel ac high-voltage has changed the circuit distribution mode of link in the past, box house will connect copper bar carry out 90 spend curved, thereby changed the installation direction of insulating sleeve.Make and under the situation of the size constancy of equipment itself, can install separable connector, both saved the convenience that the space does not influence its installation simultaneously yet at device interior.Separable connector is installed on the equipment front lower place, and installation and maintenance is convenient.The utility model adopts dividing plate just to be divided into two spaces in cabinet inside, and electrical separation is better, helps the operator safety operation.The interior cabinet door of cabinet is provided with visual window, can be in not opening checks the status of equipment in the cabinet under the situation of cabinet door at any time, the fail safe that has also improved the metal enclosed looped network switch apparatus of ac high-voltage.

Fig. 1 is the internal structure schematic diagram of the metal enclosed looped network switch apparatus of ac high-voltage of embodiment 1;
Fig. 2 is the front end view of the metal enclosed looped network switch apparatus of ac high-voltage of embodiment 1;
Fig. 3 is an A-A cross section view among Fig. 2.
Label declaration: 1-nameplate, cabinet door in the 2-housing, 3-, 4-sulphur hexafluoride on-load switch, 5-crossbeam, 6-copper bar, 7-insulative, the separable connector of 8-, 9-cable, 10-dividing plate, 11-Xiamen, 12-base plate, 13-fastening clip for cable.
Embodiment
Below with reference to the drawings and specific embodiments the utility model is described in further details:
Embodiment 1:
As Figure 1-3, the metal enclosed looped network switch apparatus of ac high-voltage comprises parts such as housing, interior cabinet door, sulphur hexafluoride on-load switch, insulating sleeve, dividing plate, copper bar, Xiamen and base plate.Housing is that material is fastenedly connected by machine-shapings such as folding, punching presses and by screw and forms with the aluminizing zine plate, copper bar, sulphur hexafluoride on-load switch and insulating sleeve link together and constitute the primary circuit of switchgear, vertically the dividing plate that is provided with is used for the installation of insulating sleeve on the one hand, forms a seal cavity in order to cut off charging space with housing on the other hand.Copper bar adopts curved sulphur hexafluoride on-load switch and the insulating sleeve with vertical distribution of 90 degree effectively to connect; The cabinet door is installed in the Xiamen in described, and equipped visual window is to be used for observation.Cable is connected on the insulating sleeve by separable connector, and cable forms with on-load switch and is electrically connected, and cable and separable connector are in the front lower place of device interior, and laterally distributed.The concrete model of three-phase load switch is FLN36.
Insulating sleeve is in vertical distribution with the sulphur hexafluoride on-load switch under the situation that guarantees effectively connection, thereby makes cable and separable connector be in the front lower place of device interior, and laterally distributed, has rationally utilized the space of equipment.
