Problems solved by technology
[0003] At present, most of the existing counters on the market will be affected by dust and high temperature. However, under the influence of high temperature and dust, the aging speed and short circuit of the internal parts of the counter will be caused, which will reduce the service life of the counter in actual use.

The invention discloses an action counter for an overvoltage protector, which comprises a base, a protection device and a box body, installation holes are arranged on the left and right sides of the base, a protection device is arranged on the upper surface of the left side of the base, and the outer surface of the protection device is provided with Handle, the outer surface on the right side of the protection device is provided with a first contact point, the left and right sides of the protection device are provided with bolt holes, the protection device is fixedly connected to the base through bolts, and the upper surface of the right side of the base is provided with a box, the user can put the first The contact and the second contact are connected by a wire, and then the protection device performs overvoltage protection on the counting device. In addition, for the convenience of the user to install, the user can install the base through the installation hole, and then connect the protection device to the counter through the bolt hole. The base is installed. Since the protection device cannot directly pull the cable by hand when accessing, a hidden handle is designed to make it more convenient for users to access.
Description
technical field [0001] The invention relates to the technical field of counters, in particular to an action counter used for overvoltage protectors. Background technique [0002] A counter is a device that can record the number of pulses and is the most commonly used logic component in digital circuits. In the digital system, the counter mainly counts the number of pulses to realize the functions of measurement, counting and control, and also has the function of frequency division. The counter is composed of a basic counting unit and some control gates, and the counting unit is composed of a series of various types of flip-flops with the function of storing information. These flip-flops include RS flip-flops, T flip-flops, D flip-flops, etc. According to different systems, it is divided into binary counters and decimal counters; according to different operation functions, it is divided into addition counters, subtraction counters and reversible counters (also known as two-w...
