Fig. 1 is a structural distribution diagram of a circuit breaker according to an embodiment of the present invention.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
The embodiment of the utility model discloses circuit breaker, it is shown with reference to figure 1, include:
an instruction receiving device 1 for receiving a test instruction;
the instruction processor 2 is connected with the instruction receiving device 1 and generates an electric leakage environment simulation instruction according to the test instruction;
the electric leakage testing device 3 is connected with the instruction processor 2 and is used for simulating an electric leakage environment according to the electric leakage environment simulation instruction;
an electric leakage control circuit 4 connected to the electric leakage test device 3;
and a circuit breaker 5 controlled by the leakage control circuit 4.
It can be seen that the circuit breaker in this embodiment actually includes two parts, one is a part for executing the function of the circuit breaker, including the leakage control circuit 4 and the circuit breaker 5, and the other is a part for testing the function of the circuit breaker, including the instruction receiving device 1, the instruction processor 2 and the leakage testing device 3.
It can be understood that the instruction receiving device 1 is only used for receiving a test instruction, and the test system of the circuit breaker generally further includes an instruction sending device 6, specifically, the instruction sending form of the instruction sending device 6 may be infrared light, and/or laser, and/or an electrical signal, where the electrical signal may be wired transmission or wireless transmission, the infrared light and the laser are remote transmission, that is, the corresponding instruction sending device 6 is an infrared remote control device or a laser remote control device, and the electrical signal device corresponding to the electrical signal sending instruction includes a mobile phone, and/or a tablet computer, and/or a single chip microcomputer, and/or a computer, the electrical signal device may send the test instruction through a wired line, and may also send the test instruction through a wireless mode, where the instruction receiving device 1 is a wireless receiving device.
It should be understood that the command receiver 1 corresponds to the Transmission Protocol of the command transmitter 6 regardless of the Transmission method of the test command, and the Transmission Protocol includes, but is not limited to, I2C (Inter-Integrated Circuit), TCP (Transmission Control Protocol), bluetooth, ZigBee, WiFi, 2G/GPRS, and other wireless data network protocols. Furthermore, if the instruction receiving device 1 and the instruction sending device 6 communicate with each other via the internet, a cloud server may be further provided to temporarily store the test instruction of the instruction sending device 6, share part of the processing work of the instruction processor 2, and ensure that the test instruction is smoothly sent to the instruction receiving device 1, so that the transmission mode realizes remote testing of the circuit breaker.
Further, the instruction processor 2 is specifically an FPGA (Field Programmable Gate Array) or a P L C (Programmable L logic Controller) or a single chip microcomputer, so that there is enough computing power to process the test instruction to generate the leakage environment simulation instruction.
The test instruction includes various information, and the instruction processor 2 is required to process the test instruction, for example, the content of the test instruction triggers the leakage test device 3 after a certain time period, or triggers the leakage test device 3 at a certain time point, or triggers the leakage test device 3 according to a test cycle in the test instruction, or adjusts and triggers the leakage test device 3 according to test parameters in the test instruction, and the like, after the instruction processor 2 obtains the test instruction, a specific leakage environment simulation instruction is generated according to the test instruction and sent to the specific leakage environment simulation instruction 3 at a specific time, so that the leakage test device 3 meets the content requirement of the test instruction.
Correspondingly, the instruction receiving device 1 may be specifically an instruction receiving device 1 that receives a timing test instruction; the instruction processor 2 may specifically be an instruction processor 2 that generates a leakage environment simulation instruction after waiting for a corresponding time according to the timing test instruction. For example, the timing test instruction received by the instruction receiving device 1 is used for performing electric leakage test for No. 1 per month at 13:00, and after receiving the timing test instruction, the test instruction processor 2 generates an electric leakage environment simulation instruction for No. 1 per month according to a clock and sends the electric leakage environment simulation instruction to the electric leakage test device 3, so that the automatic test of the timing periodicity is completed.
Besides the examples of the test instructions in this embodiment, the worker may add more setting information to the test instructions, and this is not limited herein.
Further, the electric leakage testing device 3 specifically includes a switch tube and/or an optical coupler, and the electric leakage testing device 3 can complete the simulation of the electric leakage environment by changing the state of the switch tube or the optical coupler.
When electric leakage control circuit 4 is in the electric leakage environment, if electric leakage control circuit 4 is normal, can control the disconnection of circuit breaker 5 at this moment at once, in the relay protection, power supply unit and power supply pass through circuit breaker 5 and be connected, in case circuit breaker 5 breaks off, power supply unit loses the electricity, has guaranteed power supply system's security. On the contrary, if the leakage switch 5 is not opened when the leakage testing device 3 simulates the leakage environment, it proves that there is an internal fault in the circuit breaker, specifically, in the leakage control circuit 4 and the leakage switch 5.
Further, the instruction processor 2 is further configured to: the ground fault detection circuit is connected to the disconnecting switch 5, and generates a fault determination signal when the ground fault detection circuit 3 simulates a ground fault environment but the disconnecting switch 5 is not operated.
It can be understood that the instruction processor 2 may monitor whether the circuit breaker 5 is operated by means of a current transformer or the like, and if the instruction processor 2 sends a leakage environment simulation instruction to the leakage device 3, so that the leakage environment simulation is performed, and then the circuit breaker is not operated, the circuit breaker is inevitably in a fault, and a fault determination signal is generated at this time. The fault judgment signal can be sent to a test user terminal, mainly the electric signal equipment in the foregoing, and provides test feedback for the user in various forms such as popup information, incoming call reminding, short message, mail and the like. It should be noted that, in this case, the command receiving device 1 also needs to have the function of sending commands, i.e. to be used as a two-way communication device.
Similarly, in addition to the failure determination signal, the test feedback may be configured such that the instruction processor 2 counts the time from the start of the leakage environment simulation to the operation of the disconnecting switch 5 and sends the time as the test feedback signal to the test user side, and of course, if the operation timing result of the disconnecting switch 5 is within the product allowable range, the instruction processor 2 may also directly generate a test qualified signal and send the signal to the test user side, and if the operation timing result exceeds the product allowable range or the disconnecting switch 5 is not operated all the time within the preset test time period, the failure determination signal is generated.
Meanwhile, if the instruction processor 2 generates a failure determination signal, the instruction processor 2 may immediately stop the simulation of the leakage environment of the leakage testing device 3; or, the leakage testing apparatus 3 presets a working time length for performing the leakage environment simulation each time when receiving the leakage environment simulation instruction, and is usually a preset testing time period in the upper segment, and the leakage testing apparatus 3 will automatically stop the leakage testing environment simulation after the preset testing time period is over, without the instruction processor 2 forcibly stopping the simulation.
Further, the circuit breaker may further include: and an alarm device 7 connected to the instruction processor 2 and receiving the failure determination signal.
The alarm device 7 is usually located near the duty room or the circuit breaker 5, and when the alarm device 7 receives a fault determination signal, an alarm signal is sent out to remind a field worker to overhaul the circuit breaker, and the form of the alarm signal includes buzzing, lighting and the like, which are not described in detail herein.
