Problems solved by technology

There may be situations where the electrical characteristics of the electromagnet cannot be satisfied while the amount of fastening is satisfied, or the characteristics of one group of electromagnets are satisfied but the characteristics of the second group of electromagnets cannot be satisfied, or the electrical characteristics of the electromagnet cannot be satisfied. Therefore, it seriously affects the adjustment of the product and the normal use of the subsequent product

Abstract

The invention provides an electrical and mechanical independent adjusting mechanism in a circuit breaker mechanism. The electrical and mechanical independent adjusting mechanism in the circuit breaker mechanism comprises a machine base, two sets of independently arranged tripping electromagnets which are connected with the machine base, a tripping top plate arranged above the tripping electromagnets, a tripping half shaft connected with the tripping top plate, a tripping fan-shaped plate connected with the tripping half shaft in a buckling mode, and a manually operated tripping handle connected with the tripping top plate through a connecting rod, wherein the manually operated tripping handle is arranged on the machine base, the tripping fan-shaped plate is provided with a tripping reset spring, the tripping half shaft is provided with a half shaft reset spring, a buckling amount adjusting bolt and two electrical adjusting bolts are arranged on the tripping top plate, and the two electrical adjusting bolts are located above the two sets of tripping electromagnets respectively. The electrical and mechanical independent adjusting mechanism in the circuit breaker mechanism separates the adjustment of buckling amount from the adjustment of electrical characteristics of the electromagnets, and enables the mechanical characteristics and the electrical characteristics of products to be more controllable and more stable.

Description

Technical field [0001] The invention relates to a circuit breaker structure, in particular to a structure in which the electrical characteristics of the electromagnet in the circuit breaker mechanism and the mechanical adjustment of the mechanism are separated with a low manufacturing cost. Background technique [0002] Circuit breaker is one of the main electrical equipment in substation. It can not only cut off and connect high-voltage lines and various no-load and load currents when the system is in normal operation, but also can automatically, quickly and reliably cut off various overload currents through the action of the relay protection device when the system fails And short-circuit current to prevent the occurrence and expansion of the accident scope. Sulfur hexafluoride circuit breaker is a new type of switch that uses sulfur hexafluoride gas as insulating medium and arc extinguishing medium. Sulfur hexafluoride gas is a colorless, odorless, non-toxic, non-flammable i...
