Abstract
A mobile cabinet type transformer vehicle for high-voltage load transfer comprises a transformer and a high-voltage cabinet mounted on a truck, and is characterized in that the high-voltage cabinet is a triple ring main unit including an incoming cabinet and two outgoing cabinets, the incoming cabinet is connected with a vehicular transformer, and the outgoing cabinets are provided with quick plug connectors for quick plugging of bypass transfer cables. The mobile cabinet type transformer vehicle has the advantages that power-on maintenance of fittings, such as switches, hardware, drainage wires and the like of power distribution line tension poles farer away from 400V low-voltage load is achieved through the load switch and the bypass transfer cable of the high-voltage cabinet of the mobile cabinet type transformer vehicle while bypass high-voltage power is supplied without voltage drop.
Description
Technical field
The utility model relates to power industry emergency service or upkeep operation construction field, especially distribution transformer bypass hotline maintenance construction.
Background technology
Component devices such as the transformer of distribution network system, switch, gold utensil, cable all need carry out a large amount of maintenance every year; At present, the mode of interruption maintenance is mainly adopted in the power distribution network overhaul of the equipments, and the raising along with social development requires power supply reliability becomes the development trend that car is a kind of power distribution network upkeep operation of not interruption maintenance construction becoming of bypass power supply system with movable case.
At present, becoming car with movable case is the not interruption maintenance operation of bypass power supply system, be mainly used in maintenance near the distribution transformer of 400V low-voltage load, and for away from the maintenance of annexes such as the switch of the distribution line tension force shaft tower of 400V low-voltage load, gold utensil, drainage thread, because vehicle-mounted cable length is limited, being difficult to provides the power supply of 400V low voltage bypass by mobile transformer to the terminal use.
Summary of the invention
The purpose of this utility model provides a kind of movable case that changes for high voltage load and becomes car, away from the maintenance of annexes such as the switch of the distribution line tension force shaft tower of 400V low-voltage load, gold utensil, drainage thread, can under the situation of not step-down, carry out the bypass high voltage supply for.
The technical scheme that realizes the utility model purpose is:
A kind of commentaries on classics for the movable case of high voltage load becomes car, and transformer and high-voltage board are installed on automobile, it is characterized in that: described high-voltage board adopts threefold ring net cabinet, and wherein one is incoming line cabinet, and all the other two are the outlet cabinet; A described outlet cabinet is connected with mobile transformer, and another connection outlet cabinet is provided with fast interface, and current supply cable is changeed in the bypass of can pegging graft fast.
The beneficial effects of the utility model are: for away from the maintenance of annexes such as the switch of the distribution line tension force shaft tower of 400V low-voltage load, gold utensil, drainage thread, current supply cable is changeed in the on-load switch and the bypass that become the car high-voltage board by movable case, can under the situation of not step-down, carry out the bypass high voltage supply, realize not interruption maintenance operation.
Description of drawings
Fig. 1 can change the compartment layout schematic diagram that becomes car for the movable case of high voltage load;
Fig. 2 is a high-voltage board system principle schematic diagram.
Embodiment
Embodiment 1, with reference to Fig. 1: among the figure: 1. automobile chassis, 2. compartment, 3. transformer, 4. high pressure incoming line cabinet 5. leads to the high-voltage terminal cabinet of transformer, 6. changes for high-voltage terminal cabinet, 7. inlet wire quick connector, 8. change for the high pressure quick connector, 9. the inlet wire high-tension cable 10. changes for high-tension cable.
Among the figure, compartment 2 is set on the automobile chassis 1, transformer 3, three high-voltage boards etc. are installed in the compartment 2; Three high-voltage boards comprise high pressure incoming line cabinet 4, lead to the high-voltage terminal cabinet 5 of transformer, change for high-voltage terminal cabinet 6; In the two high-voltage terminal cabinets primary cut-out or on-load switch are set; With an inlet wire high-tension cable 9 and an end that changes for high-tension cable 10, receive inlet wire quick connector 7 respectively and change on the high pressure quick connector 8, the other end is received two joints of aerial cable of tension force shaft tower both sides, and close primary cut-out or on-load switch can carry out the bypass high voltage supply.
