Description

Technical Field

[0001] The utility model relates to the technical field of leakage circuit breaker equipment, in particular to an electronic molded case leakage circuit breaker. Background Art

[0002] A circuit breaker is a switch 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 are divided into high-voltage circuit breakers and low-voltage circuit breakers according to their scope of use. The boundary between high and low voltage is relatively vague. Generally, those above 3kV are called high-voltage electrical appliances. In the existing technology, circuit breakers are fixed by bolts. When the circuit breaker is damaged or maintained, multiple bolts need to be rotated for loading and unloading. The maintenance process is cumbersome, and there is a lack of quick disassembly function for the circuit breaker, and there is also a lack of a certain buffering effect on the circuit breaker.

[0003] For example, a leakage circuit breaker disclosed in the authorized patent document with application number CN201922190025.3, wherein the releaser includes a skeleton, a main coil, a leakage coil, an overcurrent core, a leakage core, a main push rod, and a leakage push rod. The skeleton forms a main coil frame at the front side, and a leakage coil frame at the rear side. The main coil is wound outside the main coil frame, and the main coil is connected in series to the main circuit. The leakage coil is wound outside the leakage coil frame, and the leakage coil is connected to the zero-sequence mutual inductor. The overcurrent core is arranged inside the main coil frame, and a main spring is arranged between the overcurrent core and the front end of the skeleton. The main push rod is arranged in front of the overcurrent core, and the leakage core is arranged inside the leakage coil frame. The leakage push rod is arranged in front of the leakage core, and the front end of the leakage push rod is connected to the main push rod, and a leakage spring is arranged between the leakage push rod and the overcurrent core. The overcurrent protection and leakage protection of the utility model are realized by a releaser, and the structure is simple and the performance is reliable.

[0004] The above patent has the problem that the circuit breaker is fixed by bolts. When the circuit breaker is damaged or maintained, multiple bolts need to be rotated for loading and unloading. The maintenance process is cumbersome and lacks the function of quickly disassembling the circuit breaker. At the same time, it lacks a certain buffering effect on the circuit breaker. Therefore, we need to provide an electronic molded case leakage circuit breaker. Utility Model Content

[0031] The limiting mechanism 4 includes two double-threaded rods 41 rotatably mounted inside the base plate 1, and sliding seats 42 are threadedly mounted on both sides of the surface of the double-threaded rods 41.

[0033] In this embodiment, by rotating the two double-threaded rods 41, the two sliding seats 42 on the surface of the double-threaded rods 41 are moved away from each other, so that the block 43 on the surface of the sliding seat 42 is separated from the clamping and fixing relationship with the clamping groove 3 on the surface of the circuit breaker body 2, so that the circuit breaker body 2 can be taken out. At the same time, the above-mentioned movement process moves in the direction to install the circuit breaker body 2, which is convenient for loading and unloading operations on the circuit breaker body 2, and is convenient for maintenance and use. Loading and unloading operations can be achieved without tools. At the same time, a plate body 51 with placement grooves 52 is provided on the top of the base plate 1. The number of placement grooves 52 corresponds to the number of wiring harnesses on one side of the circuit breaker body 2.

The surface of the support rod 11 is integrally processed with an anti-separation portion, and the buffer sleeve 12 is set as a rubber sleeve.

[0043] The device rotates the two double-threaded rods 41 to make the two sliding seats 42 on the surface of the double-threaded rods 41 move away from each other, so that the block 43 on the surface of the sliding seat 42 is separated from the clamping and fixing relationship with the clamping groove 3 on the surface of the circuit breaker body 2, so that the circuit breaker body 2 can be taken out.
