Embodiment 1

[0050] Embodiment 1 This embodiment provides a circuit breaker with counting function, such as figure 1 As shown, it includes the circuit breaker body 1, the operating mechanism, the tripper, the moving contact part 5, the static contact 7, etc., wherein the operating mechanism, the tripping device, the moving contact part 5, the static contact 7 and other parts are all Installed on the circuit breaker body 1, a middle cover 2 is installed on the middle opening of the circuit breaker body 1, and the middle cover 2 covers the middle opening, and the above-mentioned components or structures are enclosed between the circuit breaker body 1 and the middle cover 2 In the closed space formed together after the lid is closed. The middle of the middle cover 2 is provided with an opening through which the toggle handle can pass.

[0051] combine figure 2 , image 3 As shown, the middle cover 2 of the circuit breaker body 1 is provided with an accessory chamber 2-1. In the molded cas...

Embodiment 2

[0067] Embodiment 2 This embodiment provides a counting accessory 4. The structure of the counting accessory 4 is as follows: the counting accessory 4 includes an installation housing 8, and a mechanical counter 9-4, a linkage rod 11, a pendulum, and a mechanical counter installed in the installation housing 8. The arm 10 and the return torsion spring 12 are also provided with a transparent cover 15 above the installation housing 8 to cover them. In a more preferred embodiment, the top of the installation housing 8 is provided with a left chute 8-7 and a right chute 8-8, and the transparent cover 15 can be slid and closed by the inserting plate 15-1 on it. On the installation shell 8.

[0068] The installation housing 8 is divided into upper and lower spaces. For ease of installation, a step structure is provided between the upper space and the lower space to form a limit step surface, so that when the counting accessory 4 is installed in the accessory cavity 2-1, Make sure t...

Embodiment 3

[0076] Embodiment 3 This embodiment is further set up on the basis of Embodiment 2 as follows: In order to ensure the stability of the cover between the transparent cover 15 and the installation housing 8, the side wall of the installation housing 8 is provided with a left bar-shaped Slot 8-5 and right bar-shaped slot 8-6, transparent cover body 15 is provided with limit bump 15-215-2 on the bottom surface opposite to installation shell 8 and snaps and cooperates with bar-shaped slot, so, in After the transparent cover 15 is pushed to the specified position and covers the installation shell 8, the sticking point enters the left strip-shaped slot 8-5 and the right strip-shaped slot 8-6, and the transparent cover 15 is fixed on the installation shell 8 on.

Abstract

The invention provides a counting accessory and a circuit breaker with a counting function. The counting accessory comprises an installation housing, a mechanical counter which is installed in the installation housing and is provided with a counting shaft used for counting, a linkage rod, a swing arm, and a reset torsion spring, wherein one end of the linkage rod extends out of the installation housing and is in contact cooperation with a swing part of a moving contact of the circuit breaker, one end of the swing arm is fixedly connected with the counting shaft, the other end is in linkage fitwith the other end of the linkage rod, the reset torsion spring is matched with the linkage rod and / or the swing arm in an abutting mode and used for driving the linkage rod and / or the swing arm to rotate and reset. The counting accessory provided by the invention is stable in structure, reliable, independent and convenient to disassemble and assemble, can provide technical functions for a circuit breaker without a counting function in the prior art through simple installation, improves the use functions, and meets actual requirements.

Description

technical field [0001] The invention relates to the field of low-voltage electrical appliances, in particular to a counting accessory for counting closing and opening times, and a circuit breaker with the function of counting closing and opening times. Background technique [0002] The molded case circuit breaker is a widely used electrical device. In addition to protecting the circuit, it is also often used as a switch. Therefore, in actual use, there are cases where the molded case circuit breaker frequently connects and breaks the current under the normal circuit. . At present, the common molded case circuit breakers on the market do not have the function of counting the number of closing and opening times, and the usage status depends on the subjective impression of the user. When used for a long time, users are often unable to judge the service status and life of the circuit breaker. Due to the limited service life of the molded case circuit breaker, if it is not repla...
