Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of double grading having control and scheduling co-design electrical equipment concurrently, has fine arc extinguishing ability, stronger breaking capacity and higher reliability and compared with the full controlling electric energy of long life and protection switch.
In order to solve the problems of the technologies described above, full controlling electric energy of the present utility model and protection switch, the moving contact comprising a pair hard-wired fixed contact and coordinate with two fixed contacts, also comprise the arc control device be arranged on outside the contact of moving contact and the contact of fixed contact, the arc extinguishing grid pieces for arc extinguishing is provided with in arc control device, moving contact is arranged on one between two fixed contacts and can on the moving contact rack of action between two fixed contacts, there is the permanent-magnet operating mechanism for controlling moving contact rack knee-action the below of moving contact rack, permanent-magnet operating mechanism comprises the dynamic iron core being fixedly connected on moving contact rack bottom, the permanent magnet being wrapped in the divide-shut brake coil outside dynamic iron core and being arranged on below dynamic iron core, permanent magnet is fixedly mounted on a base, a Compress Spring is provided with between moving contact rack and base.
Described divide-shut brake coil is set to two absolute coils be simultaneously wrapped on dynamic iron core, two absolute coil connecting dividing lock loops respectively.
Described dynamic iron core is arranged on a coil brace with interior circular hole, and the cross sectional shape of dynamic iron core is set to excise by cylinder the column structure that two sides are formed.
After adopting above-mentioned structure, due to the arc extinguishing unit arranged, divide-shut brake unit and permanent-magnet operating mechanism, dexterously by the collection high breaking capacity that has of circuit breaker and comprehensive protective value and contactor have to circuit is powerful structure simple, reliability is high, mechanical endurance is long, the consistency operate time characteristic such as good is in one, make its overall structure simple, breaking capacity is strong, arc extinguishing ability is good, reliability is high, consistency is good, frequent operation control can be carried out, conjunction explains state without electric energy loss, reclosing reaches 200,000 times mechanical endurance, electric life 10,000 times, discreteness ± 3ms, the absolute coil simultaneously arranged, absolute coil has different divide-shut brake loops, improve the agility of disjunction, the cross sectional shape of dynamic iron core is set to excise by cylinder the column structure that two sides are formed, the dynamic gap formed between iron core and the interior circular hole of coil brace, decrease resistance, further increase divide-shut brake speed, thoroughly eliminate conventional electromagnetic contactor thus to divide, it is slow that speed is explained in conjunction, all shortcomings such as adhesive keeps power consumption not environmentally, and in the protective capability to circuit and equipment, meet or exceed the characteristic of circuit breaker, product is made to have double grading and the advantage of control and scheduling co-design electrical equipment, what the control and scheduling co-design of distribution was become is more succinct, for user saves a large amount of equipment investments, the multiple electrical equipment in low-voltage distribution and control system can be substituted, reduce volume, reduce costs, improve reliability, save a large amount of non-ferrous metals and equipment and materials and valuable electric energy.
