Description

Technical Field

[0001] The utility model particularly relates to a pole-mounted circuit breaker position state detection device. Background Art

[0002] At present, outdoor 10kV pole-mounted vacuum circuit breakers are basically intelligent products. During operation, they almost all use wireless communication methods. Users obtain various operating status of the circuit breaker through the background: energy storage or no energy storage, closed position, and open position. Sometimes it is found that the background cannot detect certain status of the circuit breaker, or there is no energy storage or no energy storage information, or no closed position information, or no open position information, which creates obstacles to the normal operation of the line.

[0003] The main reason for the above phenomenon is that the circuit breaker status detection is neglected during the circuit breaker production process or factory inspection. Because the product commissioning and detection are carried out through the intelligent distribution automation feeder terminal (FTU), firstly, some FTU operation panels do not have alarm or status display functions, and secondly, the circuit breaker status signal does not affect the circuit breaker opening and closing functions, which may cause detection loopholes.

If the specific posture changes, the directional indication will also change accordingly.

[0024] The utility model discloses a pole-mounted circuit breaker position status detection device, which includes a detection circuit and a power supply arranged in a box body. At the same time, fixing holes for installing an indicator component and a detection terminal are provided on either side of the box body. The indicator component and the detection terminal are fixed to the box body by means of crimping. At the same time, the inner part is directly connected to the detection circuit to form a detection loop.

[0025] The box body has an installation space therein and is made of metal, which can be aluminum alloy. It encloses the charged components of the entire detection device and can prevent external interference from affecting the detection results.

[0026] The indicator assembly is disposed on either side of the housing and partially within the mounting space. In this embodiment, three different color sound and light alarms are employed: red, yellow, and green. The alarms are integrated with sound and light, providing both visual and audible detection results, ensuring reliable detection.

[0027] The test terminal is used to connect to the pole-mounted circuit breaker under test, with one end extending into the mounting space. In this embodiment, a 26-core aviation plug is used. It directly and reliably connects to the 26-core aviation socket of the pole-mounted circuit breaker under test. This allows for plug-and-play operation, preventing any interruptions to the connection between components.

[0028] The power supply E is arranged in the installation space and is used to provide working power. This embodiment adopts a safe 12V DC power supply, and a rechargeable lithium battery can also be used.

Each detection circuit is electrically connected to a corresponding indicating component, and the three parallel detection circuits are respectively connected to the trigger switch of the circuit breaker on the pole to be tested through the detection terminal.

[0032] The open position detection circuit and the closed position detection circuit are connected to the auxiliary switch DL of the pole-mounted circuit breaker to be tested through detection terminals.

[0033] The non-energy-storage position detection circuit is connected to the travel switch CK of the circuit breaker on the pole to be tested through the detection terminal.

[0034] Through three parallel detection circuits, which are respectively connected to corresponding indicating components, corresponding signal output is achieved by relying on the conduction of each detection circuit.

[0035] Specific testing process
