Embodiment Construction

[0026] Such as Figure 1-Figure 8 As shown, the embodiment of the present invention is specifically a reclosing device for a prepaid circuit breaker, which includes a housing 1 and a cover 2. The shapes of the housing 1 and the cover 2 are matched to form an inner space for internal parts to be placed together. cavity. The housing 1 and the cover 2 are provided with a slide switch 3 , a wiring device 4 , a handle device 5 and a driving device 6 for controlling the opening and closing of the slide switch 3 . The slide switch 3 includes a static contact piece 31 installed in the housing 1 , a moving contact piece 32 and a fan-shaped transmission piece 33 that can drive the moving contact piece 32 to rotate accordingly. The static contact piece 31 contacts and cooperates with the movable contact piece 32 , the circle center of the fan-shaped transmission piece 33 is arranged on the inner wall of the housing 1 , and the movable contact piece 32 is arc-shaped. The movable contact...

Abstract

The invention discloses a reclosing device of a prepayment breaker. The reclosing device comprises a shell and a cover. The shell is internally provided with a sliding switch, a junction device, a handle device and a driving device for controlling turning off and turning on of the sliding switch. The sliding switch comprises a fixed contact sheet, a movable contact sheet and a sector-shaped transmission sheet. The circle center of the sector-shaped transmission sheet is rotationally arranged on the inner wall of the shell. The movable contact sheet is in an arc shape and is arranged along the outer arc edge of the sector-shaped transmission sheet. The section, close to the movable contact sheet, of the fixed contact sheet is a fixed contact sheet arc part which is provided with a fixed contact sheet notch dividing the fixed contact sheet into two parts. The movable contact sheet is tightly attached to the fixed contact sheet arc part. The side, close to the handle device, of the sector-shaped transmission sheet is provided with a transmission wheel tooth. The driving device comprises a sector-shaped gear sheet and a driving motor. According to the reclosing device, by means of the cooperation between the movable contact sheet and the fixed contact sheet arc part, the turning on of the sliding switch arranged in the N electrode is earlier than that of a switch in the P electrode of the breaker, turning off of the sliding switch in the N electrode is later than that of the switch in the P electrode of the breaker, and non-arc turning off of the N electrode can be achieved.

Description

technical field [0001] The invention relates to the technical field of circuit breaker prepaid devices, in particular to a prepaid circuit breaker reclosing device. Background technique [0002] According to the demand for intelligent power supply network in my country, the State Grid Corporation of China requires circuit breakers to realize the intelligent power supply network, and requires remote control at the end user to perform functions such as closing, tripping, and prepayment, and has issued relevant standards. Such as "Technical Specifications for External Load Switches for Electric Energy Meters". The standard stipulates that there are six types of load switches according to the number of poles, among which, 1P+N is a two-pole load switch with a protective pole). It is required to realize the prepayment and reclosing functions in the 2P circuit breaker and circuit breaker reclosing device with a total thickness of about 36mm, and its rated short-circuit breaking ca...
