Description

Technical Field

[0001] The utility model relates to the technical field of circuit breakers, and more specifically, to a residual leakage circuit breaker with electricity measurement and early warning. Background Art

[0002] A residual current circuit breaker is a circuit breaker that can protect against leakage current. In addition to providing protection against overload and short circuit of power lines or equipment, its main function is to provide indirect contact protection against the danger of electric shock to people due to insulation damage of power lines and equipment; at the same time, it provides protection against fire hazards and other faults that may be caused by long-term grounding faults that cannot be detected by overcurrent protection devices. Residual current operated protection circuit breakers with a rated leakage current not exceeding 30mA can also be used as additional protection against direct contact when the relevant protection fails.

[0003] When the leakage current of the protected line or equipment reaches the action value specified by the product, the internal protection device of the leakage circuit breaker drives the release to operate, so that the leakage circuit breaker disconnects the protected circuit and protects the line or electrical equipment.

[0004] Among them, it was found through searching that the patent application number CN201720175718.3 discloses a residual leakage circuit breaker. It includes a shell, the shell includes a base and a middle cover, the base is provided with a contact system, a power source and an operating handle, one end of the operating handle is provided in the base and connected to the contact system and used to drive the contact system to move, and the other end passes through the middle cover, and an eccentric shaft is provided on the power source, one end of the eccentric shaft is connected to the power source and driven by the power source to rotate around the center of the power source, and the other end passes through the middle cover and is connected to the operating handle through a connecting rod;

[0005] When this structure is in use, a power source and an operating handle are provided, and the contact system can be reliably operated by the operating handle. The setting of the power source enables the power source to reliably receive signals and drive the operating handle to operate, and the operation is fast and reliable. However, this structure is not easy to connect when in use, and it is not easy to quickly reset the connection after power failure, so it is not convenient enough when in use. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the utility model provides a residual leakage circuit breaker with electric measurement and early warning, aiming to solve the problems raised in the above-mentioned background technology.

[0007] The utility model is implemented in this way. The utility model provides the following technical solutions: a residual leakage circuit breaker with electric detection and early warning, comprising a support plate for supporting, and a connecting assembly is arranged on the support plate;

[0008] The connection assembly comprises a reinforced nylon partition plate arranged on the top of the support plate and used for supporting, a shell is arranged on one side of the reinforced nylon partition plate, a display screen is arranged on the shell, and a plurality of arc extinguishing chambers are arranged on the other side of the reinforced nylon partition plate;

[0009] Insulators are arranged at the bottom of the plurality of arc extinguishing chambers, and a wiring pin is arranged at the bottom of each of the insulators, and a lower extension column is arranged at the bottom of the wiring pin;

[0010] A pull rod is provided at the bottom of the lower extension column, one end of which extends to the reinforced nylon partition and is movably connected to the reinforced nylon partition through an axle pin, one end of which is provided with an extension rod, the outer side of which is provided with an insulating sleeve, the bottom of the lower extension column extends to the pull rod, and a return spring is provided at the top of the pull rod and located on the outer side of the lower extension column;

[0011] It can be seen that in the above technical solution, the axis point of the connection between the pull rod and the reinforced nylon partition is rotated by the extension rod, which then causes the pull rod to deflect and pull the lower extension column to move and compress the reset spring. After the extension rod and the pull rod lose their limit, the lower extension column can be reset by the elasticity of the reset spring itself, so that the wiring pin can contact the insulator for current transmission, which is easy to quickly reset and connect together.

[0012] Optionally, in a possible implementation manner, both sides of the arc extinguishing chamber, the insulator and the lower extension column are provided with protective baffles for protection, the protective baffles extend to the reinforced nylon baffles and are detachably connected to the reinforced nylon baffles, one end of the pull rod is provided with a dislocation frame opening on the surface of the reinforced nylon baffle, and the pull rod is located in the dislocation frame opening;

[0013] It can be seen that in the above technical solution, through the provision of protective partitions, the arc extinguishing chamber, insulators and lower extension columns installed on the reinforced nylon partitions can be protected to ensure the stability of their installation and the safety of the device during operation.

[0014] Technical effects and advantages of the utility model:

[0015] By setting the connection assembly, compared with the prior art, the overall design is simple and the structure is reasonable. Through the corresponding coordination of various structures, the wire is connected to the wiring pin, which makes it easy for the wiring pin to transmit the current to the arc extinguishing chamber through the insulator;

[0016] Pulling the extension rod drives the axis point of the connection between the pull rod and the reinforced nylon partition to rotate, which in turn causes the pull rod to deflect and pull the lower extension column to move and compress the reset spring. After the extension rod and the pull rod lose their limit, the lower extension column can be reset by the elasticity of the reset spring itself, so that the wiring pin can contact the insulator for current transmission, which is easy to quickly reset and connect together, thereby improving the convenience of the device when in use.
