[0002] The circuit breaker is a key electrical device. Its main function is to open and close the circuit. Specifically, the circuit breaker can close, carry and break the current under normal circuit conditions, and can close, carry and break the current under abnormal circuit conditions within a specified time.

[0030] The following embodiments are described in detail, and examples thereof are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementations described in the following embodiments do not represent all implementations consistent with the present application. They are only examples of systems and methods consistent with some aspects of the present application as detailed in the claims.

[0031] To solve the problem of not being able to quickly detect the mechanical characteristics and aging of permanent magnet mechanisms, see Figure 3 , Figure 3The present application provides a permanent magnet mechanism rapid detection device, comprising: a control switch, a time relay, a switching power supply, a printed circuit board assembly, a switching switch, a closing push button switch, an opening push button switch, a freewheeling circuit printed circuit board assembly, a counter and a socket.

[0032] The control switch is respectively connected to the input end of the switching power supply and the power input end of the time relay; the output end of the switching power supply is respectively connected to the input end of the printed circuit board assembly and the input end of the switching switch; the normally closed output end of the switching switch is respectively connected to the closing push button switch and the opening push button switch; the normally open output end of the switching switch is connected to the time relay; the closing push button switch and the opening push button switch are respectively connected to the printed circuit board assembly, the time relay and the socket; the time relay is connected to the counter; the freewheeling circuit printed circuit board assembly is respectively connected to the printed circuit board assembly and the socket.

[0033] It should be understood that there is a chip inside the printed circuit board assembly, which is a dual-electric control program chip. The switching power supply can be an AC220V to DC110V switching power supply, which is used to convert alternating current (AC220V) into direct current (DC110V). The control switch can be a 3A-2P air switch, which is used to control and protect the circuit. Among them, "3A" means that the rated current of the switch is 3 amperes, and "2P" means that it has two poles (i.e., incoming and outgoing lines), which can control the live wire and the neutral wire at the same time.

[0034] When the mechanical characteristics of the permanent magnet mechanism need to be detected, first connect the closing coil and opening coil of the permanent magnet structure to be detected to the HQ+ / FQ+ and HQ- / FQ- lines of the socket, and connect the switch mechanical characteristics tester to the SWF / SWH and C- lines of the socket. Then connect the speed sensor of the switch mechanical characteristics tester to the outer shaft of the permanent magnet mechanism moving iron core, and finally connect the 220V AC power supply and turn on the control switch, and press the closing button switch to detect the closing speed, and press the opening button switch to detect the opening speed to detect the mechanical characteristics. When the aging of the permanent magnet mechanism needs to be detected, first connect the closing coil and opening coil of the permanent magnet structure to be detected to the HQ+ / FQ+ and HQ- / FQ- lines of the socket, and then connect the 220V AC power supply and turn on the control switch, then set T1 and T2 of the time relay to 4 seconds respectively, and press the switch to make the permanent magnet mechanism reciprocate the closing and opening actions at intervals of 4 seconds, and count the closing actions through the counter to detect the aging. This can then quickly verify the reliability of the permanent magnet mechanism and solve the problem of being unable to quickly detect the mechanical properties and aging of the permanent magnet mechanism.

[0035] In some embodiments, the switching switch includes a manual mode and an automatic mode, and the working mode of the permanent magnet mechanism rapid detection device can be switched. The switching switch button pops up to the manual mode; the closing button switch is pressed, and the detection device outputs a closing command, and the permanent magnet mechanism completes the closing action; the opening button switch is pressed, and the detection device outputs an opening command, and the permanent magnet mechanism completes the opening action. After the switching switch button is pressed, after adjusting the delay time of the time relay, the closing and opening commands will be output alternately, realizing the alternating closing and opening actions of the permanent magnet mechanism, and completing a fixed number of aging tests. At the same time, the counter completes the counting of the aging times.

[0036] In some embodiments, the control switch includes a power switch, which is connected to a DC power source or an AC power source through a power line. The power switch facilitates fast switching between the DC power source and the AC power source.

[0037] In some embodiments, the AC power supply is 220V AC power; the DC power supply is 77V-144V DC power. 220V AC power has a wider universal range and is easy to replace and use. 77V-144V DC power is easy to control and adjust.

[0038] In some embodiments, the permanent magnet mechanism rapid detection device further includes a switch mechanical characteristic tester. The socket is connected to the switch mechanical characteristic tester and the permanent magnet mechanism respectively; the speed sensor of the switch mechanical characteristic tester is connected to the outer shaft of the moving iron core of the permanent magnet mechanism. The permanent magnet mechanism rapid detection device is equipped with a switch mechanical characteristic tester, which is more convenient for measuring and detecting the mechanical characteristics of the permanent magnet mechanism.

[0039] In some embodiments, the socket is a 10-core socket. The 10-core socket is not only convenient for users to connect multiple devices on the same plug board at the same time, reducing device crowding, but also has a strong load capacity and is more suitable for permanent magnetic mechanism rapid detection devices.

[0040] In some embodiments, the permanent magnet mechanism rapid detection device further comprises a chassis. The control switch, time relay, switch power supply, printed circuit board assembly, switch, closing push button switch, opening push button switch, freewheeling circuit printed circuit board assembly, counter and socket are arranged inside the chassis and fixedly connected to the chassis by screws and buckles.

[0041] It should be understood that the chassis may be a dedicated chassis of 360 mm × 340 mm × 150 mm.

Figure 2 , Figure 2 This is a rear panel layout diagram of a permanent magnet mechanism rapid detection device. The rear panel of the chassis is equipped with a 10-core socket, a DC110V input interface, and a herringbone socket with a switch. In addition, the DC110V switching power supply, the printed circuit board assembly, and the freewheeling circuit printed circuit board assembly are fixed to the chassis bottom plate by screws. The chassis is convenient for placing and fixing all internal components, playing a supporting and protective role.

[0042] In some embodiments, the permanent magnet mechanism rapid detection device further comprises a count reset switch connected to the counter, and the count reset switch controls the count value of the counter to return to zero so as to restart counting.

[0043] In some embodiments, the control switch, time relay, switching power supply, printed circuit board assembly, switching switch, closing push button switch, opening push button switch, freewheeling circuit printed circuit board assembly, counter and socket are all connected through FOT wire ring or terminal block plus parallel plate.

[0044] It should be understood that the devices are connected by crimping FOT wire rings at both ends of the cable, and the lines are connected in parallel by terminal blocks plus parallel pieces. Connection through FOT wire rings or terminal blocks plus parallel pieces is more convenient and stable.

[0045] In some embodiments, the time relay is a DH48S-S time relay.

[0046] DH48S-S time relay has a high brightness LED display, which can clearly show the delay time period. Its delay range is wide and users can preset it arbitrarily, which is very flexible. DH48S-S time relay has high precision, small size, low power consumption, reliable performance, and has pause and reset functions, which enables it to achieve infinite cycle start during operation.

[0047] In some embodiments, the normally open end of the closing button switch is connected in series with the normally closed end of the opening button switch; the normally open end of the opening button switch is connected in series with the normally closed end of the closing button switch. This can reduce the occurrence of malfunctions caused by the mistaken operation of pressing the closing button switch and the opening button switch at the same time.

[0048] It can be seen from the above technical scheme that the present application provides a permanent magnet mechanism rapid detection device, including: a control switch, a time relay, a switching power supply, a printed circuit board assembly, a switching switch, a closing push button switch, an opening push button switch, a freewheeling circuit printed circuit board assembly, a counter and a socket.
