Abstract
A mechanical switchover device for a public electricity distributor comprises a printed circuit board (1), a drive motor (2), and a rotating arm (7). A central hole (3) is arranged at the middle part of the printed circuit board, and an annular electrode (4) concentric with the central hole is arranged on one surface of the printed circuit board; a plurality of second electrodes (5) which are arranged in a ring shape and have an equal interval are arranged on the periphery of the annular electrode, and the ring formed of the second electrodes is concentric with the annular electrode; the drive motor (2) is fixed on the other surface of the printed circuit board (1), and the shaft (6) of the drive motor passes through the central hole (3); and one end of the rotating arm (7) is fixed at the end of the shaft of the drive motor, and a moving electrode (8) is fixed on the rotating arm and has the two ends thereof contacting with the annular electrode and one second electrode respectively. The mechanical switchover device provided by the utility model can be installed inside the public electricity distributor to replace a relay to conduct switchover operation of a power supply. The device can tolerate high on/off current so as to improve the reliability of the public electricity distributor.
Description
Technical field
The utility model relates to and a kind of the building public electricity-using is assigned to the structure of the parts of the public electricity-using divider that carries out electric energy metrical in each electric supply meter, a kind of public electricity-using divider mechanical type switching device equably.
Background technology
Adopt relay to have advantage simple in structure, reliable operation as the public electricity-using divider of main switch element.But used relay is owing to the restriction in divider space, and general volume is less, and capacity is also less, when public load capacitive or perception are big, bigger at the moment impact electric current that is switched on or switched off, can between the contact, produce electric spark, make air ionization, cause that sometimes interpolar punctures and damages.
Summary of the invention
The utility model is intended to propose a kind of public electricity-using divider mechanical type switching device, can replace the relay in the public electricity-using divider, and power supply is transferred.
This public electricity-using divider mechanical type switching device comprises a bar printing wiring board, a drive motors and a cursor.There is a centre bore at the middle part of printed substrate, be with an annular electrode concentric at centre bore outer on the face of printed substrate with centre bore, annular electrode is with several second electrodes that circularizes arrangement and spacing equalization outward, and the annular that second electrode arrangement becomes is mutually concentric with annular electrode.The another side of printed substrate is being fixed drive motors, and the axle of drive motors passes centre bore.One end of cursor is fixed on the end of the axle of drive motors, is fixing a moving electrode on the cursor, and the two ends of moving electrode contact with annular electrode and one second electrode respectively.
This public electricity-using divider mechanical type switching device can be installed in the public electricity-using divider and replace relay, finishes the switch over operation to power supply.Electrode in the public electricity-using divider mechanical type switching device can be done greatlyyer, can tolerate bigger switching electric current, improves the reliability of public electricity-using divider.And the printed substrate in the public electricity-using divider mechanical type switching device can lump together with the circuit board of public electricity-using divider, makes the structure of public electricity-using divider obtain simplifying.

Fig. 3 is public electricity-using divider mechanical type switching device application principle figure.
Embodiment
As depicted in figs. 1 and 2, this public electricity-using divider mechanical type switching device comprises a bar printing wiring board 1, a drive motors 2 and a cursor 7.There is a centre bore 3 at the middle part of printed substrate, be with an annular electrode 4 concentric at centre bore outer on the face of printed substrate with centre bore, annular electrode be with outward several circularize arrange and annular that second electrode, 5, the second electrode arrangement of spacing equalization become mutually concentric with annular electrode.The another side of printed substrate 1 is being fixed drive motors 2, the axle 6 of drive motors passes centre bore 3, one end of cursor 7 is fixed on the end of the axle of drive motors, is fixing a moving electrode 8 on the cursor, and the two ends of moving electrode contact with annular electrode and one second electrode respectively.Cursor 7 is own non-conductive, by moving electrode 8 annular electrode 4 and each second electrode is transferred.
The application of this public electricity-using divider mechanical type switching device as shown in Figure 3.Each second electrode 5 in the public electricity-using divider mechanical type switching device is joined with each user's ammeter output terminals A respectively, the power end B of annular electrode 4 and public electricity-using load 10 is joined the other end connecting to neutral line N of public electricity-using load.Drive motors 2 is driven by drive circuit 9, regularly moving electrode 8 is turned over lattice by the time interval of setting, and the electric energy of public electric loading consumption is shared on each electric supply meter equably.
Drive motors 2 in this public electricity-using divider mechanical type switching device can be a reducing motor, also can be a stepping motor.
Claims (1)
