Description
Technical field
The utility model belongs to circuit breaker component parts technical field, specifically just relates to a kind of double breaking points movable contact system with closed compensate function, improves stability and the reliability of double-breakpoint contact system action.
Background technology
Circuit breaker is divided into primary cut-out and low-voltage circuit breaker by its scope of application.Low-voltage circuit breaker, also known as automatic switch, is commonly called as " air switch " and also refers to low-voltage circuit breaker, and it is a kind of existing hand switch effect, automatically can carry out again decompression, under-voltage, overload and the electrical equipment of short-circuit protection.It can be used to distribute electric energy; infrequently start asynchronous motor; protection is carried out to power circuit and motor etc.; can automatic shutdown circuit when serious overload or short circuit and the fault such as under-voltage occur for they; its function is equivalent to Fuse switch and the combination of crossing underheat relay etc.; and generally do not need to change parts after disjunction fault current, obtain a wide range of applications.
Along with the continuous increase of net capacity and the needs of centralized power distribution, electrical equipment requires that its breaking capacity is more and more higher, so the extensive use in breaker of plastic casing of current-limiting type structure of contact terminal, the particularly circuit breaker of double-breakpoint structure, because arc energy is born by two contacts, breaking capacity also improves further, and it obtains in recent years and develops more widely; But existing product structure is in order to ensure the reliability and stability of two contact action, to the processing technology of part contact and material requirements very high, product cost is caused to increase severely, after carrying out electric life test and the large short circuit current of disjunction, contact there will be scaling loss on the other hand, cause there are differences between two contacts, can not synchronization action, scaling loss can be accelerated to the serious contact of scaling loss when continuing to use, reducing product reliability.
Utility model content
The purpose of this utility model is for existing double-breakpoint contact system, there is scaling loss in contact after carrying out electric life test and the large short circuit current of disjunction, the technological deficiency of product reliable breaking can not be reduced by synchronization action, a kind of double-breakpoint contact system with closed compensate function is provided, there are differences between upper and lower static contact, not when a contact-making surface, moving contact first contacts the contact face that stroke is close with it, produce contact pressure, the counter-force now produced moving contact is greater than torsion or the moving contact initial pressure of moving contact spring, moving contact swings, thus play the effect of differential compensation, ensure contact reliable contacts, improve the reliability of circuit breaker disjunction.
Technical scheme
In order to realize above-mentioned technical purpose, a kind of double breaking points movable contact system with closed compensate function of the utility model design, it comprises contact base and dynamic touch panel, it is characterized in that: described dynamic touch panel is contained on contact base by left torsion spring and right torsion spring, left torsion spring and right torsion spring are contained on the erection column of contact base both sides respectively, left one end pushes down the left haptic element of dynamic touch panel, groove is propped up on the left side that the other end props up on contact base, right one end pushes down the right haptic element of dynamic touch panel, and groove is propped up on the right side that the other end props up on contact base;
Described contact base upper surface is provided with boss, and boss props up dynamic touch panel.
Further, described boss height 0.7mm, the centre position between left haptic element and right haptic element.
Further, described contact base upper surface is provided with positioning convex, and positioning convex stretches in the positioning port on dynamic touch panel.
Further, described positioning convex is taper, and taper positioning convex props up locating notch.
Beneficial effect
A kind of double-breakpoint contact system with closed compensate function that the utility model provides, there are differences between upper and lower static contact, not when a contact-making surface, moving contact first contacts the contact face that stroke is close with it, produces contact pressure, and the counter-force now produced moving contact is greater than torsion or the moving contact initial pressure of moving contact spring, moving contact swings, thus play the effect of differential compensation, ensure contact reliable contacts, improve the reliability of circuit breaker disjunction.
