Embodiment 1

[0026] An embodiment of the present invention provides a low temperature resistant miniature circuit breaker reclosing device, such as figure 1 , figure 2 As shown, it includes: a casing 1, the upper end of the casing 1 is inlaid with a planetary cycloid mechanism wrench 2, and a position sensor 21 is installed on the planetary cycloid mechanism wrench 2, and the planetary cycloid mechanism wrench 2 is connected to the planetary cycloid mechanism wrench 2. The slot bar 3 is coaxially connected, the slot bar 3 of the planetary cycloid mechanism is U-shaped, the slot bar 3 of the planetary cycloid mechanism matches the planetary cycloid pin 4, and the planetary cycloid pin 4 is controlled by the swing arm 41 and coincidence pin 42, the planetary cycloid pin 4 is bearing-connected with the gear assembly 5, and the gear assembly 5 is composed of a first gear 51, a second gear set 52 and a third gear set 53, and the second gear 52 is composed of a second large gear 521 and a seco...

Embodiment 2

[0050] An embodiment of the present invention provides a method for using a low temperature resistant miniature circuit breaker reclosing device, such as image 3 shown, including:

[0051] 201. Connect the external power supply to the external power socket 9, and connect the bus and signal lines to the bus and signal terminals 10 respectively.

[0052] 202. The detector 8 obtains the real-time position information of the planetary cycloid mechanism wrench 2 through the position sensor 21. The planetary cycloid mechanism wrench 2 is coaxially connected with the planetary cycloid mechanism groove bar 3, and judges the coincidence pin 42 according to the real-time position information. Whether the groove lever 3 of the planetary cycloid mechanism is currently disconnected.

[0053] 203. When the coincidence pin 42 is disconnected from the slot rod 3 of the planetary cycloid mechanism, the detector 8 sends a start signal to the motor 7, the motor 7 starts, and the motor 7 drives...

Abstract

The invention discloses a low-temperature-resistant micro circuit breaker reclosing apparatus and a use method therefor, and relates to the field of a reclosing apparatus; the low-temperature-resistant micro circuit breaker reclosing apparatus solves the problem that the existing reclosing apparatus cannot work at low temperature, and can be used in outdoor environments at the temperature below minus 30 DEG C, so that the applicable scope of the reclosing apparatus is enlarged, and the reclosing apparatus has market potential. The low-temperature-resistant micro circuit breaker reclosing apparatus adopts the match of a planet cycloid mechanism groove rod and a planet cycloid pin, and the reclosing apparatus has the unique brake-separating position and unique break-reclosing position, the shortcoming that the existing reclosing apparatus judges by fully relying on sensors is solved, and the reclosing apparatus is higher in reliability. The technical key point is as follows: the low-temperature-resistant micro circuit breaker reclosing apparatus comprises a housing, a planet cycloid mechanism spanner, a planet cycloid mechanism groove rod, a planet cycloid pin, a gear module, a motor-driven gear, a motor, a detector, an external power supply socket, a bus, a signal terminal, a work indicating lamp, a reclosing failure indicating lamp and a clamping pin. The low-temperature-resistant micro circuit breaker reclosing apparatus is mainly used for reclosing of the micro circuit breakers, micro leakage protectors and other electric appliances.

Description

technical field [0001] The invention relates to the field of circuit breaker reclosing devices, in particular to a low temperature resistant miniature circuit breaker reclosing device and a use method thereof. Background technique [0002] Micro Circuit Breaker (Micro Circuit Breaker) refers to a switching device that can close, carry and break current under normal circuit conditions. It can be used to distribute electric energy, start asynchronous motors infrequently, and protect power lines and motors. When they occur It can automatically cut off the circuit in case of serious overload or short circuit and undervoltage faults. Its function is equivalent to the combination of fuse switch and overheating and underheating relay. The circuit breaker reclosing device is a motor operating mechanism with the same shape and size as the miniature circuit breaker. It is composed of a motor, a speed reduction gear set, and a control circuit, which can drive the circuit breaker to clo...
