[0002] With the continuous construction and upgrading of distribution network systems, new requirements have been placed on the changing characteristics of the distribution network. Supporting equipment needs stronger and more reliable controllability to ensure its performance, composition, and functions operate accurately and without error during grid connection. Therefore, the main body of the deeply integrated 1-2 system switch and the FTU must undergo functional testing before being put into operation. Currently, the remote signaling function testing of the FTU, whether conducted in the manufacturing plant or by third-party testing, relies on the circuit breaker body providing closed, open, and stored / unstored signals for the controller FTU to complete this function test. When testing the main body of the deeply integrated 1-2 system switch and the FTU, the remote signaling function test must be performed connected to the circuit breaker body, which is extremely inconvenient. Without the circuit breaker body, this function cannot be achieved. Utility Model Content

Detailed Implementation

[0024] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0025] Example

[0026] like Figures 1-8 As shown, the portable FTU remote signaling detector for a deep primary and secondary integrated circuit breaker of this utility model includes a housing 1 and a self-locking switch 2 with an indicator light. The self-locking switch 2 with an indicator light is mounted on the top of the housing 1, and a fourteen-pin aviation connector 4 is mounted on the bottom of the housing 1. A relay 3 is arranged between the self-locking switch 2 with an indicator light and the fourteen-pin aviation connector 4. The relay 3 is fixed in the middle position inside the housing 1.

[0027] The indicator light pin of the self-locking switch 2 with indicator light is connected to CZ3 and CZ4 at point 4 of the 14-pin aviation connector; the normally open pin of the self-locking switch 2 with indicator light is connected to CZ5 and CZ6 at point 4 of the 14-pin aviation connector; KM1 and KM16 at point 3 are connected to the closing circuit, KM2 and KM15 are connected to the opening circuit, and KM4, KM6, and KM8 are connected to CZ6, CZ2, and CZ1 at point 4 of the 14-pin aviation connector, respectively, corresponding to the common terminal, the open position, and the closed position; the controller FTU supplies power to the closing circuit, and relays KM1 and KM1 at point 3 are energized and activated, and the controller FTU collects the closing signal; the controller FTU supplies power to the opening circuit, and relays KM2 and KM15 at point 3 are energized and activated, and the controller FTU collects the opening signal;

[0028] Specifically, such as Figures 1-8 As shown, the indicator light pins of casing 1 are connected to CZ3 and CZ4 at point 4 of the 14-pin aviation connector. The indicator light illuminating indicates that the controller FTU energy storage circuit is functioning normally. The normally open pins of the self-locking switch 2 with indicator light are connected to CZ5 and CZ6 at point 4 of the 14-pin aviation connector. When switch button 202 is pressed, the normally open pins of casing 1 and the self-locking switch 2 with indicator light change to normally closed. At this time, the controller FTU energy storage signal light illuminates, indicating that the controller energy storage circuit signal acquisition is normal. Relays KM1 and KM16 at point 3 engage the circuit breaker, KM2 and KM15 connect to the circuit breaker opening, and KM4, KM6, and KM8 are connected to CZ6 and CZ2 at point 4 of the 14-pin aviation connector, respectively. CZ1 corresponds to the common terminal, open position, and closed position of the signal. When the controller FTU supplies power to the closing circuit, relays KM1 and KM2 at point 3 are energized and activated, and the controller FTU collects the closing signal. When the controller FTU supplies power to the opening circuit, relays KM2 and KM15 at point 3 are energized and activated, and the controller FTU collects the opening signal. Based on the working principle of the FTU, it provides signal points for the closed, open, unenergized, and energized positions to the controller to simulate the state of the circuit breaker, thereby accurately determining whether the remote signaling function of the controller FTU is correct. The remote signaling function of the FTU can also be achieved without the circuit breaker body itself.

[0029] The self-locking switch with indicator light 2 includes a set of switch buttons 202, and an indicator light strip 201 is set around the switch buttons 202. The normally open pins and indicator light pins of the self-locking switch with indicator light 2 are set accordingly.

[0030] like Figure 1 , Figure 2 As shown, the housing 1 integrates a self-locking switch 2 with indicator light, a relay 3, and a 14-pin aviation connector 4. It is small in size and light in weight, and is not limited by time or location. It can be used with FTU for testing at any time. The internal components are all common products on the market, which are low in cost. The housing 1 is made of aluminum alloy, which is durable, has a long lifespan, and is more portable.

[0031] A locking structure 5 is provided between the outer casing 1 and the self-locking switch 2 with indicator light.

The self-locking switch with indicator light 2 is fixed by the locking structure 5, and the fourteen-pin aviation connector 4 is closed by the cover plate 6. When disassembling, the locking rod 504 can be pulled out horizontally to disengage the housing 1 and the self-locking switch with indicator light 2. The self-locking switch with indicator light 2 can be lifted upwards for disassembly. When disassembling the fourteen-pin aviation connector 4, the four sets of mounting bolts 7 are removed and the cover plate 6 is opened to take out the fourteen-pin aviation connector 4, thus realizing the disassembly and replacement of the components.

[0033] The working principle of this portable deep primary and secondary fusion circuit breaker FTU remote signaling detector is as follows: The indicator light pins of the outer casing 1 are connected to points CZ3 and CZ4 of the 14-pin aviation connector. When the indicator light is on, it indicates that the controller's FTU energy storage circuit is normal. The normally open pins of the self-locking switch 2 with indicator light are connected to points CZ5 and CZ6 of the 14-pin aviation connector. When the switch button 202 is pressed, the normally open pins of the self-locking switch 2 with indicator light on the outer casing 1 change to normally closed. At this time, the controller's FTU energy storage signal light illuminates, indicating that the controller's energy storage circuit signal acquisition is normal. Relays KM1 and KM16 at point 3 engage the circuit breaker, KM2 and KM15 engage the circuit breaker, and KM4, KM6, and KM8 engage the circuit breaker. The fourteen-pin aviation connectors are connected to four locations: CZ6, CZ2, and CZ1, corresponding to the common signal terminal, open position, and closed position. The controller FTU supplies power to the closing circuit, and relays KM1 and KM1 at location 3 are energized and activated. The controller FTU then collects the closing signal. Similarly, the controller FTU supplies power to the opening circuit, and relays KM2 and KM15 at location 3 are energized and activated. The controller FTU collects the opening signal. Based on the FTU's working principle, it provides signal points for the closed, open, unenergized, and energized positions to the controller, simulating the circuit breaker's state. This allows for accurate determination of whether the controller FTU's remote signaling function is correct. This remote signaling function can also be achieved without the circuit breaker itself.
