Description
Technical field
The utility model is related to vacuum circuit breaker technical field, and in particular to a kind of electromagnetic type anti-rebounding device and with adjust
Save the breaker of opening velocity function.
Background technology
" vacuum circuit breaker " gains the name because the dielectric of contact gap after its arc-extinguishing medium and arc extinguishing is all high vacuum；Its
Have the advantages that it is small, light-weight, do not have to maintenance suitable for frequent operation, arc extinguishing, using more popularizing in power distribution network.Very
Empty breaker is 400V~10kV, the indoor distribution in 50Hz three-phase alternating current systems, for industrial and mining enterprises, power plant, change
Protection and control in power station as electrical equipment are used, especially suitable for requiring making for non-oil ultra high vacuum system, few maintenance and frequent operation
With place, breaker is configurable in middle-placed switch cabinet, double-layer cabinet, fixed cabinet and is used as control and protection high voltage electric equipment.
Existing vacuum circuit breaker mechanism is spacing using rigid separating brake, also has using oily buffer unit, both mechanism arrangements
The separating brake bounce-back amplitude of breaker can be allowed to be controlled.But when breaker trip is smaller, open away from it is smaller when, it is desirable to breaker
Opening velocity is very fast, to reach reliable separating brake.At this time, mechanism still uses rigid limit device, then rebounds during breaker open operation
Amplitude can be very big, or still can not be realized stroke design requirement less than normal using oily buffer unit, oil buffering again, both can be made
Arcing, re-breakdown phenomenon occurs into breaker.It is therefore desirable to a kind of mechanism of new anti-rebounding device is designed, when breaker point
Lock is very fast, opens away from the case of less, bounce-back amplitude during reducing breaker open operation, while adjustable breaker open operation speed
Degree.
