The power supply changeover box comprises a box body, the first input end is an earth line terminal, the second input end is a live line terminal, the third input end is a null line terminal, the second input end and the third input end are connected with a residual current device (RCD) through a knife switch (S1), an alternating-current ammeter is connected in series with the output end of the residual current device (RCD), and a power indicator light (L1), a double-hole socket (XS1), a three-hole socket (XS3) and an alternating-current voltmeter are connected in parallel with the output ends of the residual current device (RCD). According to Tthe power supply changeover box, mainly expands the output ends can be expanded, enhances safety and reliability can be enhanced, and increases the field working efficiency can be increased.
Description
Technical field
The present invention relates to the electric power switching device technical field.
Background technology
Transformer station, the place of change voltage.For power delivery that the power plant is sent to place far away, must raise voltage, become high-tension electricity, near the user more on demand lower voltage, the work of this lifting voltage is finished by transformer station.The capital equipment of transformer station is switch and transformer.Press scale different, be called electric substation, switchgear house etc.When station, constantly be unable to do without temporary source, we find to move in the transformer station maintenance power box of that different times is produced, different manufacturers, the different modes of connection, the installation wiring button that terminals in the power supply box have, the mounting receptacle that has, the installation disconnecting link that has bring inconvenience for on-the-spot use.In addition, the on-the-spot appliance tool that uses is more, as: brake switch tester, electric wrench, direct resistance metering instrument etc., if all arrive the power supply box wiring, very inconvenient.
Summary of the invention
Technical problem to be solved by this invention provides a kind of power supply transfer case, and multiple power sources output can be provided, and can intuitively observe electric current and voltage, can satisfy the demand of various electrical equipment, has characteristics easy to use, safe and reliable.
For solving the problems of the technologies described above; the technical solution used in the present invention is: a kind of power supply transfer case; comprise casing; it is characterized in that first input end is the ground wire terminals; the second input is hot terminal; the 3rd input is the zero line terminals; the second input and the 3rd input meet earth leakage protective device RCD through disconnecting link S1; alternating current ammeter is connected on the output of earth leakage protective device RCD, and power supply indicator L1, Double-hole socket XS1, Three-hole socket XS3 and A.C. voltmeter are connected in parallel on the output of earth leakage protective device RCD.
Preferably: be parallel with input plug X1 on described zero line terminals and the hot terminal.
Preferably: the output of earth leakage protective device RCD is parallel with two groups of above wiring and turns round sub-XS2.
Preferably: the output of earth leakage protective device RCD is parallel with two winding lines and turns round sub-XS2.
The beneficial effect that adopts technique scheme to produce is: in the described transfer box earth leakage protective device is housed, the elements such as voltmeter, ammeter, ground wire terminals, supply terminals, Double-hole socket, Three-hole socket, has following characteristics: 1, safe and reliable: when earth leakage protective device is housed, the equal reliable ground of all hardwares, and can observe intuitively electric current and voltage; 2, possessing two kinds of input connected modes can select: no matter mains side is socket, or binding post, all can reliably connect; 3, three kinds of way of outputs: satisfy the different modes of connection such as wiring button, Three-hole socket and Double-hole socket.4, portable, enclosed construction: described transfer box comprises casing, is convenient to transportation, uses safety.Described transfer box mainly is to have expanded output, is suitable for the demand of different electrical equipment, has improved safety and reliability, has improved simultaneously work on the spot efficient.
Description of drawings
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
Fig. 1 is electrical schematic diagram of the present invention.
Embodiment
A kind of power supply transfer case comprises casing, and the first input end of described transfer box is the ground wire terminals, and the second input is hot terminal, and the 3rd input is the zero line terminals.The second input and the 3rd input meet earth leakage protective device RCD through disconnecting link S1; the second input and the 3rd input form one group of input of described transfer box; alternating current ammeter is connected on the output of earth leakage protective device RCD, and the output that sub-XS2 is connected in parallel on earth leakage protective device RCD is turned round in power supply indicator L1, Double-hole socket XS1, Three-hole socket XS3, A.C. voltmeter and two groups of above wiring.Be parallel with input plug X1 on described zero line terminals and the hot terminal, as another group input of described transfer box.
In use, at first use short-circuit line to be connected with the ground wire terminals of described transfer box, with casing ground connection; Then, hot terminal is connected with power supply with the zero line terminals, hot terminal and zero line terminals have two kinds of connected modes, and a kind of is plug-type, and another kind is the terminals minors; The last output different according to different electrical appliance choice for uses, after connecting that casing is closed, prevent from the process of operation, touching the electric elements in the casing.Input and the disconnection of disconnecting link S1 control power supply, indicator light L1 is used for showing whether electricity is arranged.
In the described transfer box earth leakage protective device is housed, the elements such as voltmeter, ammeter, ground wire terminals, supply terminals, Double-hole socket, Three-hole socket, have following characteristics: 1, safe and reliable: when earth leakage protective device is housed, the equal reliable ground of all hardwares; 2, possessing two kinds of input connected modes can select: no matter mains side is socket, or binding post, all can reliably connect; 3, three kinds of way of outputs: satisfy the different modes of connection such as wiring button, Three-hole socket and Double-hole socket.4, portable, enclosed construction: described transfer box comprises casing, is convenient to transportation, uses safety.Described transfer box mainly is to have expanded output, is suitable for the demand of different electrical equipment, has improved safety and reliability, has improved simultaneously work on the spot efficient.
Used specific case herein principle of the present invention and execution mode thereof are set forth, the explanation of above embodiment is just with helping understand method of the present invention and core concept thereof.Should be pointed out that for the person of ordinary skill of the art, can also carry out some improvement and modification to the present invention under the prerequisite that does not break away from the principle of the invention, these improvement and modification also fall in the protection range of claim of the present invention.
