Abstract
The utility model relates to an internal contactor for an automatic change-over switch, in particular to an electric switch that changes the load circuit to another (standby) power source under emergent condition, which belongs to the technical field of power supply change-over equipment. The utility model is characterized in that: a movable contactor is plugged into a rocker and is positioned inside a shell body together with the busbar of load; a main power source busbar is positioned at the right side of the shell body; a standby power source busbar is positioned at the left side of the shell body. The utility model has the advantages of; simple, compact and feasible structure; because little current instant electromagnetic driving is adopted , the time for the change-over of the contactor is less than 35mms; the 6 times current change-over out of phase is safer and configured with anti-shock function; the main and standby change-over space can be adjusted, which greatly improves the arc elimination performance of the switch and ensures the connection of important load and reliable operation.
Description
Technical field
The utility model relates to a kind of automatic transfer switching electric appliance inside contact, specifically be used in emergency system, be with the device for switching of load circuit from an automatic changing-over of power supply to another (standby) power supply, to guarantee that important load connects, reliability service belongs to power supply conversion equipment technical field.
Background technology
Before the utility model was made, in prior art, the automatic transfer switching electric appliance inside contact mainly was made up of housing, main electricity (standby) source bus, moving contact and rocking arm etc.Stand-by power supply bus and main power source bus are contained in housing the same side, and distance is shorter between stand-by power supply bus and main power source bus, has only about 20mm.Therefore its change-over time and arc extinction performance are relatively poor, do not reach the performance of automatic conversion, and the out-phase of six times of electric currents are changed safety inadequately.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, thereby provide a kind of stand-by power supply bus and main power source bus are installed in the housing both sides, distance is far away between making it, change-over time and arc extinction performance are improved a lot, the out-phase conversion of six times of electric currents is safer, thereby reaches the automatic transfer switching electric appliance inside contact of automatic conversion.
Main solution of the present utility model is achieved in that
The utility model mainly comprises housing 1, primary, spare power source bus 2,5, rocking arm 3, moving contact 4, wait to levy is that moving contact 4 inserts in the rocking arm 3 and load bus 6 is mounted in the housing 1, main power source bus 2 is installed in housing 1 right side, and stand-by power supply bus 5 is installed in housing 1 left side.
Compared with the prior art the utility model has the following advantages:
The utility model is simple, compact and reasonable for structure; Owing to use little electric current moment Electromagnetic Drive, smaller or equal to 35 millimeters seconds, the conversion of the out-phase of 6 times of electric currents is safer, and has shockproof function during the contact conversion; Can adjust active and standby conversion spacing, improve the switch arc extinction performance greatly, connect reliability service to guarantee important load.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:
The utility model mainly is made up of housing 1, primary, spare power source bus 2,5, rocking arm 3, moving contact 4, stand-by power supply bus 5, load bus 6 etc.
The utility model is placed on housing 1 on the desktop, and moving contact 4 inserts in the rocking arms 3, with screw be installed in the housing 1 after load bus 6 is connected, main power source bus 2 is installed in housing 1 right side, stand-by power supply bus 5 is installed in housing 1 left side.5 distances of main power source bus 2 and stand-by power supply bus are 55～65mm.The utility model automatic transfer switching electric appliance (ATSE) is applied in important electricity consumption place, and its reliability is particularly important.
