Description

Technical Field

[0001] The present invention relates to the technical field of circuit breakers, and in particular to an energy consumption metering type direct current intelligent circuit breaker. Background Art

[0002] A circuit breaker is a switching device that can close, carry and disconnect current under normal circuit conditions and can close, carry and disconnect current under abnormal circuit conditions within a specified time. Circuit breakers can be used to distribute electrical energy, start asynchronous motors infrequently, and protect power lines and motors. When they have serious overloads, short circuits, undervoltage and other faults, they can automatically cut off the circuit. Its function is equivalent to the combination of a fuse switch and an over-underheating relay, and generally no parts need to be changed after disconnecting the fault current. At present, it has been widely used.

[0003] The public (announcement) number CN213398700U disclosed a metering device and a circuit breaker, including: a housing, and a detection component and a sampling circuit board installed in the housing; the detection component includes a current transformer and a high-precision transformer; the current transformer and the high-precision transformer have a clearance hole for the conductive busbar to pass through, and the sampling circuit board is electrically connected to the current transformer and the high-precision transformer. The metering device provided by the utility model alleviates the technical problem of adding a metering transformer outside the circuit breaker and occupying the cabinet volume in the related art.

[0004] In the above-mentioned prior art solution, when the circuit breaker is in use, the fixing frame needs to be fixed to the inside of the housing by screws. If the snap device of the circuit breaker is damaged, the two screws of the fixing frame need to be removed to remove the fixing frame from the housing, which makes the disassembly and assembly more cumbersome and wastes time.

[0005] To this end, we propose an energy consumption metering type DC intelligent circuit breaker. Summary of the invention

[0006] The present invention mainly solves the technical problems existing in the above-mentioned prior art and provides an energy consumption metering type DC intelligent circuit breaker.

[0007] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: an energy consumption metering type DC intelligent circuit breaker, comprising a distribution box, a circuit breaker body, a live wire interface and a meter, wherein placement blocks are symmetrically fixed on the inner wall of the distribution box, and positioning blocks are fixedly connected at both ends of the bottom of the circuit breaker body, and the positioning blocks are horizontally provided with slots, and the placement blocks are provided with positioning grooves, and a fixing frame is fixedly connected to the bottom of the placement block, and a limiting groove is provided on the top of the fixing frame. A limiting rod is fixedly connected to the inner cavity of the fixing frame, and both ends of the limiting rod are slidably connected to the limiting slide, and both ends of the limiting rod are sleeved with reset springs, and plug rods are fixedly connected to the limiting slide.

[0008] Preferably, the limiting slide plate is integrally of an L-shaped structure and is adapted to the limiting groove.

[0009] Preferably, the mutually remote ends of the return springs are fixedly connected to the wall surface of the inner cavity of the fixed frame, and the mutually close ends of the return springs are fixedly connected to the mutually remote wall surfaces of the limiting slide plate.

[0010] Preferably, the plug rod and the plug slot are mutually adapted and are both of a cross-shaped structure.

[0011] Preferably, a plurality of ventilation grooves are formed on both side wall surfaces of the circuit breaker body, and an alarm is installed on one side of the top of the circuit breaker body.

[0012] Preferably, an anti-slip pad is fixedly connected to the inner cavity wall surface of the placing block.

[0013] Preferably, a transparent observation door is hinged to the front surface of the circuit breaker body.

[0014] The present invention provides an energy consumption metering type DC intelligent circuit breaker. It has the following beneficial effects:

[0015] 1. For the energy consumption metering type DC intelligent circuit breaker, through the cooperation of the limiting slide plate, the limiting rod, the return spring, the plug rod and the plug slot, the limit on the positioning block can be released, the circuit breaker body can be moved upward away from the placing block, and the positioning block is released from the inner cavity of the positioning groove, and then the circuit breaker body can be quickly disassembled, so that the disassembly and assembly are simpler, time is saved, and the work efficiency is improved.

[0016] 2. For the energy consumption metering type DC intelligent circuit breaker, through the setting of the transparent observation door on the circuit breaker body, the user can conveniently observe the reading of the meter. This transparent observation door not only provides a convenient metering monitoring function, but also can effectively protect the meter from the external environment; at the same time, the observation door plays a sealing and protecting role, preventing dust, moisture, etc. from entering the circuit breaker, so as to ensure the stability and service life of the circuit breaker body.

[0017] 3. For the energy consumption metering type DC intelligent circuit breaker, since a plurality of ventilation grooves are formed on both side wall surfaces of the circuit breaker body, the ventilation grooves can effectively promote air circulation during the operation of the circuit breaker, which helps to take away the heat generated by the current passing through. This design enhances the heat dissipation performance of the circuit breaker, reduces the risk of overheating, helps to maintain the normal operation of the equipment, extends the service life, and ensures its stability and safety.

[0018] 4. For this energy consumption metering type DC intelligent circuit breaker, through the setting of the alarm, when a fault occurs in the circuit breaker body, the alarm can emit an obvious sound to prompt the user. This function helps to detect circuit faults in a timely manner, avoid equipment damage or safety hazards caused by ignoring problems, ensure that the operator can perform maintenance in the first place, and thus guarantee the safe and stable operation of the electrical system.

[0019] 5. For this energy consumption metering type DC intelligent circuit breaker, an anti-slip pad is installed on the outer wall surface of the circuit breaker body, which can effectively prevent the circuit breaker from slipping during placement. This design not only reduces the risk of slipping, but also effectively avoids scratching the outer wall of the circuit breaker on the placement surface and reduces external damage. The application of the anti-slip pad provides additional protection, while ensuring the safety of the circuit breaker during transportation and storage, and this design does not add additional complex structures, maintaining the simplicity and practicality of the equipment.
