Abstract
Description
Technical Field
[0001] The utility model relates to an anti-interference leakage circuit breaker. Background Art
[0002] In traditional circuits, manufacturers use circuit breakers to prevent overloading of voltage and current, and can also ensure that the switch can be reset after tripping. Therefore, the circuit breaker set on the circuit switch can effectively reduce the risk and cost of circuit anomalies. However, since circuit switches need to be integrated together, generally the switches of the overall circuit are combined and integrated in a control box. In this way, if magnetic flux devices are used to control each switch, the switch will be affected in the current magnetic field, affecting the normal use of the switch.
[0003] In this process, the protector for protecting the circuit and the switch is more vulnerable to magnetic field influence. Therefore, in conventional circuits, mechanical structures are always used for tripping protection. Such structures are not as safe as magnetic flux structures and cannot achieve the sensitivity of magnetic flux structures. However, the magnetic flux structure itself is a structure that is adjusted according to magnetic field changes. Once exposed to an environment full of magnetic fields, it is very easy to be affected. Therefore, it cannot be used in high-voltage and high-current control cabinets. Summary of the Utility Model
[0004] The technical problem to be solved by the utility model is to provide an anti-interference leakage circuit breaker, aiming to separate the magnetic flux sensing element from the circuit breaker, reduce the proportion of magnetic flux in the main circuit through a pin-type connection method, and at the same time use the shell of the magnetic flux component to protect it, reducing the influence of external interference on the magnetic flux component.
[0005] To solve the above technical problem, the technical solution of the utility model is: an anti-interference leakage circuit breaker, including a magnetic flux component, a connection component and a tripping component; the magnetic flux component is located on one side of the connection component and is connected to the protection circuit at the same time, providing the power required for tripping through the voltage and current changes of the protection circuit; the connection component is located between the tripping component and the magnetic flux component, transmitting the power provided by the magnetic flux component to realize the movement of the tripping component; the tripping component is located on one side of the connection component, one end is connected to the connection component, and one end is connected to the main circuit to control the opening or closing of the main circuit;
[0006] The described magnetic flux component includes an anti-interference housing, a magnetic flux coil, a permanent magnet, and a connection pin; the anti-interference housing is located on one side of the connection component and wraps the magnetic flux coil and the permanent magnet; the magnetic flux coil surrounds the permanent magnet and is located inside the anti-interference housing; the permanent magnet is located at the center of the magnetic flux coil, with one end extending outward to cooperate with the connection component; the connection pin is located below the magnetic flux coil and connects the magnetic flux coil, and further connects the protection circuit.
[0007] The described connection component includes a connection spring piece, a transmission torsion spring, a telescopic spring, and a release plate; the connection spring piece is located above the permanent magnet and cooperates with the permanent magnet; the transmission torsion spring is located on one side of the connection spring piece, with one end connected to the connection spring piece and the other end connected to the telescopic spring; the telescopic spring connects the release plate and also connects the transmission torsion spring, and drives the release plate to move up and down through telescoping; the release plate abuts against the release component, and the release component is inserted into the connection component to press down the release plate, and the telescopic spring is stretched to maintain the connection. When the magnetic flux component generates power under the influence of current, the connection spring piece rotates upward, driving the transmission torsion spring to rotate, and at the same time driving the telescopic spring to move upward. When the power is greater than the elastic force of the telescopic spring, it will drive the release plate to move upward and abut against the release component. Due to the movement of the release plate, it occupies the original position of the release component, causing the release component to move horizontally and disengage from the connection component, realizing tripping and completing the protection action.
[0008] Further, the anti-interference housing extends outward and cooperates with the connection component to support the connection component.
[0009] Further, a connection plate is provided above the telescopic spring; the connection plate has an "L" - shaped outer shape and includes a horizontal plate and a vertical plate; the horizontal plate is located below the vertical plate and is connected to the telescopic spring; the vertical plate is located outside the horizontal plate and is connected to the transmission torsion spring.
[0010] Further, the telescopic spring is in a stretched state when connecting the release component.
[0011] Further, the connection component is also provided with a connection port, which is located on one side of the anti-interference housing, is electrically connected internally, cooperates with the release component, and is externally connected to the main circuit.
[0012] Further, a socket is provided on the release component, and the socket is inserted into the connection component to achieve electrical connection.
[0013] Furthermore, an anti-magnetic gasket is provided inside the anti-interference housing to prevent the magnetic flux coil and the permanent magnet from being affected by external magnetic fields.
[0014] Furthermore, the anti-interference housing is made of a metal that resists magnetic interference, generally alloy steel.
[0015] Compared with the prior art, an anti-interference leakage circuit breaker provided by the present utility model comprehensively wraps the magnetic flux assembly through the anti-interference housing, which can prevent the magnetic flux assembly from being interfered by external magnetic fields. At the same time, the circuit is connected through the connection structure of the plug pins, effectively reducing the layout space and tripping steps of the circuit connection, reducing the complexity of the circuit tripping. When the circuit is normally connected, the telescopic spring is in a stretched state, which can reduce the power required for the magnetic flux work and save energy consumption.
