Abstract
The utility model relates to a double power source automatic switching cabinet, which comprises a cabinet body (5) which is composed of a double power source automatic switching section (1) and a wire connection section (2), wherein an indicating lamp (3) and a button (4) are arranged on the double power source automatic switching section (1), and the double power source automatic switching section (1) of the two sections has a drawer type structure. The circuit parts of the double power source automatic switching section (1) and the wire connection section (2) comprise an automatic changeover switch GLD, and two input ends of the GLD are respectively connected to a first power source and a second power source in the wire connection section. The output end of the GLD is connected to the input end of a load branch switch which is arranged in the wire connection section. The utility model is characterized in that the wire connection mode of a drawer type switch can be increased. When the switch of the utility model is maintained and replaced, the power supply of the power source can be interrupted for a shorter time and the operation is easy and quick.
Description
Technical field: the utility model relates to a kind of duplicate supply automatic switchover cabinet, is mainly used in the electrical engineering of public building, industry and civil buildings.
Background technology: like product of the prior art can realize that double loop power supply automaticallyes switch, but safeguards complicated and trouble when changing switch.Reason is when operation, needs to interrupt the power supply power supply, changes the time that switch needs several hrs, makes troubles to the user.Some special user is unacceptable to this.
Summary of the invention: the purpose of this utility model is at above-mentioned the deficiencies in the prior art, only needs the short time to interrupt the power supply power supply when safeguarding and change switch and provide a kind of, and changes simple and easy, the duplicate supply automatic switchover cabinet conveniently of switching manipulation.For achieving the above object, the utility model adopts following technical proposals: duplicate supply automatic switchover cabinet, comprise cabinet (5), and cabinet (5) is made up of duplicate supply automatic switchover district (1), Wiring area (2).Duplicate supply automatic switchover district (1) is provided with indicator light (3) and button (4), and duplicate supply automatic switchover district (1) is a drawer-type structure in above-mentioned two districts.The circuit part of described duplicate supply automatic switchover district (1) and Wiring area (2) comprises automatic change-over GLD, and the two-way input of GLD is connected to road power supply UN and two road power supply UR in the Wiring area respectively.The output of GLD is connected to the input of the load branch switch in the Wiring area.
Characteristics of the present utility model are to have increased the drawer type switch mode of connection, make it only need the short time to interrupt the power supply power supply when safeguarding and change switch, and easy operation.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is an electrical schematic diagram of the present utility model.
Fig. 3 is a secondary electrical schematic diagram of the present utility model.
Embodiment:
With reference to Fig. 1-3, duplicate supply automatic switchover cabinet comprises cabinet 5, and cabinet 5 is made up of duplicate supply automatic switchover district 1, Wiring area 2.Duplicate supply automatic switchover district 1 is provided with indicator light 3 and button 4, and duplicate supply automatic switchover district 1 is a drawer-type structure in above-mentioned two districts.The circuit part of described duplicate supply automatic switchover district 1 and Wiring area 2 comprises automatic change-over GLD, and the two-way input of GLD is connected to one road power supply UN and two road power supply UR respectively.The output of GLD is connected to the input of the load branch switch in the Wiring area.The auxiliary terminal 301,302,303,304 of GLD is connected with three indicator lights 4 (HG1-3) in duplicate supply automatic switchover district, and 202,204 terminals are connected with button 5.Fuse FU connects with indicator light as the protection component of indicator light, and is connected with zero line N with the phase line L of GLD output.Relay K A1 is connected with 403 with auxiliary terminal 603 respectively with KA2.
Operation principle: during normal power supply, GLD places auto state, automatically detection, Switching power.When GLD need safeguard or change, GLD is placed manual state, place zero tunnel, interrupt powering to the load, at this moment, can extract GLD out, maintenance or replacing.Switch returns to the normal power supply state after repairing.
