Abstract
The utility model relates to an automatic switching dual power source and bypass cabinet, which comprises a cabinet body (7) which is composed of a bypass on-off section (1), a dual power source automatic switching section (2) and a wire connection section (3), wherein the dual power source automatic switching section (2) of the three sections has a drawer type structure. The circuit portion of the bypass on-off section (1), the dual-power source automatic switching section (2) and the wire connection section (3) comprises a manual switching switch GLZ and an automatic switching switch GLD. Two input ends of the manual switching switch GLZ are respectively connected to a one-way power source and a two-way power source of the wire connection section, and two input ends of the automatic switching switch GLD are respectively connected with the one-way power source of the wire connection section and the two output ends of the manual switching switch GLZ. The output end of the manual switching switch GLZ and the output end of the automatic switching switch GLD are connected in parallel and are connected to a load branch switch of the wire connection section. The utility model is characterized in that a drawer type on-off connection mode and the bypass design can be increased. When the switch of the utility model is maintained and replaced, the power source supply can not be interrupted and the operation is easy and quick. The utility model has an electrical interlocking function, a mechanical interlocking function and favorable safety performance.
Description
Technical field: the utility model relates to a kind of duplicate supply and automaticallyes switch and the bypass 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, and changing switch needs the several hrs time, makes troubles to the user.Some special user is difficult to this accept.
Summary of the invention: the purpose of this utility model is at above-mentioned the deficiencies in the prior art, and a kind of uninterrupted power supply power supply when safeguarding and change switch is provided, and the replacing switching manipulation is simple and easy, conveniently duplicate supply automaticallyes switch and the bypass cabinet.For achieving the above object, the utility model adopts following technical proposals: duplicate supply automaticallyes switch and the bypass cabinet, comprises cabinet (7), and cabinet (7) is made up of by-pass switch district (1), duplicate supply automatic switchover district (2), Wiring area (3).By-pass switch district (1) is provided with indicator light (6), and duplicate supply automatic switchover district (2) is provided with indicator light (4) and button (5).Duplicate supply automatic switchover district (2) is a drawer-type structure in above-mentioned three districts.The circuit part of described by-pass switch district (1), duplicate supply automatic switchover district (2) and Wiring area (3) comprises manual change-over switch GLZ and automatic change-over GLD.The two-way input of GLZ is connected to one road power supply UN and two road power supply UR of Wiring area respectively, and the two-way input of GLD is connected to one road power supply UN of Wiring area and two road outputs of GLZ respectively.The road output of GLZ and the output of GLD also are attached to the load branch switch of Wiring area.
Characteristics of the present utility model are to have increased the drawer type switch mode of connection and bypass design, make its uninterrupted power supply when safeguarding and change switch power, and easy operation, this programme have the function of electrical interlocks and mechanical chain and good security performance.

Embodiment:
With reference to Fig. 1-3, duplicate supply automaticallyes switch and the bypass cabinet, comprise cabinet 7, cabinet 7 is made up of by-pass switch district 1, duplicate supply automatic switchover district 2, Wiring area 3, by-pass switch district 1 is provided with indicator light 6, duplicate supply automatic switchover district 2 is provided with indicator light 4 and button 5, and duplicate supply automatic switchover district 2 is a drawer-type structure in above-mentioned three districts.The circuit part of described by-pass switch district 1, duplicate supply automatic switchover district 2 and Wiring area 3 comprises manual change-over switch GLZ and automatic change-over GLD, the two-way input of GLZ is connected to one road power supply UN and two road power supply UR of Wiring area respectively, and the two-way input of GLD is connected to one road power supply UN of Wiring area and two road outputs of GLZ respectively.The road output of GLZ and the output of GLD also are attached to the load branch switch of Wiring area 3.The auxiliary terminal 301,302,303,304 of GLD is connected with three indicator lights 4 (HG1, HG2, HG3) in duplicate supply automatic switchover district, and 202,204 terminals are connected with button 5.Auxiliary terminal 1F10, the 2F10 of GLZ is connected with by-pass switch district indicator light 6 (HG4, HG5).602 are connected with the output phase line L of GLD by FU1 with 402, and 603 are connected with KA2 with relay K A1 respectively with 403.Fuse FU1, FU2 be respectively as the automatically switch protection component of district and bypass district indicator light of duplicate supply, and series connection with it is connected with zero line N with the phase line L of the output of GLD, GLZ respectively again.
Operation principle: during normal power supply, GLD places auto state, and GLZ places the II road, i.e. right wing closure, and left road disconnects.When GLD need safeguard or change, GLZ is placed the I road, promptly left road closure, right wing disconnects, and forms bypass.GLD as for manual state, is placed zero-bit.At this moment, can extract GLD out, maintenance or replacing.Switch returns to the normal power supply state after repairing.
