Problems solved by technology

[0003] In order to solve the problem that the switch part of the DC circuit breaker is easy to age and burn out, the inventor thought of using a conductive liquid as the switch part of the DC circuit breaker. As a liquid substance, the conductive liquid has good self-repairability in electrical properties; Cost and complexity reduction, the inventor thought of using electromagnetic force to push the conductive liquid to flow in the gravity seesaw to realize the automatic switch function

Embodiment 1

[0031] Such as Figure 1-2 As shown, a mechanical DC circuit breaker that can be used in electric or electronic systems includes a horizontal bar body (1), a support body (2), a connector (3), 2 electric rails (4), a magnet (5), a conductive liquid(6);

[0032] The horizontal bar body (1) is connected with the supporting body (2) through a rotating connection (12) to form a gravity seesaw;

[0033] The bar body (1) has a cavity (10) for accommodating the conductive liquid (6), and the cavity (10) straddles the fulcrum of the gravity seesaw jointly formed by the bar body (1) and the support body (2) perpendicular;

[0034] The conductive liquid (6) is loaded in the cavity (10) of the bar body (1), and the volume of the conductive liquid (6) is less than half of the effective volume of the cavity (10) of the bar body (1);

[0035] The length of the electric track (4) is less than half of the transverse length of the cavity (10) of the bar body (1);

[0036] Two electric rail...

Embodiment 2

[0046] Connect a diode in series on the electrical path between Y+ and Y- to prevent miswiring.

Embodiment 3

[0048] The DC circuit breaker described in Example 1 is used for overcurrent protection of DC power lines.

Abstract

A mechanical-type direct current breaker applicable to an electric or electronic system comprises a crosswise bar body (1), a bearing body (2), a connector (3), two electric rails (4), a magnet (5) and a conducting liquid (6). An electrical machine is provided with the above direct current breaker. The direct current breaker and the electrical machine are long in service life, simple in structure and low in cost.

Description

technical field [0001] The invention belongs to an electrical switch, and in particular relates to a mechanical direct current circuit breaker and an electric machine which can be used in electric power or electronic systems. Background technique [0002] Because the DC circuit breaker is easy to pull the arc when it is disconnected, the switch part of the DC circuit breaker is easy to age and burn; there are many methods in the prior art to try to eliminate the aging and burn of the switch part, but there is room for improvement (such as: structure It is always difficult to take into account the complexity, cost, and lifespan). Contents of the invention [0003] In order to solve the problem that the switch part of the DC circuit breaker is easy to age and burn out, the inventor thought of using a conductive liquid as the switch part of the DC circuit breaker. As a liquid substance, the conductive liquid has good self-repairability in electrical properties; In order to r...
