Description
Technical field
The present invention relates to the electric switch field, be specifically related to a kind of automatic transfer switching electric appliance of AC/DC mixing device.
Background technology
Existing automatic transfer switching electric appliance on the market generally has the two-way power input, one road power output end.This type of automatic transfer switching electric appliance can only be used for switching between the connatural power supply of two-way, promptly selects alternating-current switch when exchanging for use at the two-way power supply, and the two-way power supply is selected dc switch during for direct current for use.
In actual applications, many electricity consumptions place is arranged, have one the tunnel to be that power supply exchanges in its power supply commonly used and the stand-by power supply, and other one the tunnel is the power supply direct current, just need a kind of automatic change-over, can between AC power and DC power supply, carry out the conversion of power supply with AC/DC mixing device.
Summary of the invention
The object of the present invention is to provide a kind of automatic change-over of AC/DC mixing device, have two and overlap independently converting system, can be respectively to AC power with DC power supply is connected and disjunction, and the assurance alternating current-direct current can not be connected simultaneously, realized loading on the conversion between AC power and DC power supply, overcome existing automatic change-over transfer process and can't realize the deficiency switched between AC power and the DC power supply.
The present invention is by base plate, main control part, arc-control device A and B, the input terminal of AC side, main shaft, moving contact, lead-out terminal, fixed contact, the input terminal of DC side, main shaft, moving contact, lead-out terminal, fixed contact and insulation board constitute, main control part, AC side switch sections, DC side switch sections all are fixed on the base plate, the switch sections of interchange and DC side is arranged on the both sides on the base plate, assurance has enough electric clearances, middle with the insulation board isolation, guarantee non-interference between the two-way power supply.
The moving contact of the main shaft control AC side of AC side and the break-make between the AC side fixed contact, fixed contact is connected with load, and moving contact is connected with ac input end in rotation process all the time.The moving contact of the main shaft control DC side of DC side and the break-make between the DC side fixed contact, fixed contact is connected with load, and moving contact makes end and direct-flow input end connect in rotation process.Control section is being controlled the rotation of AC side main shaft and DC side main shaft, because control section adopts " V " type mechanism, can guarantee that the two-way power supply can not close simultaneously, promptly have only a side power supply branch to have no progeny, the opposite side power supply is just connected, between the regular hour gap is arranged, guarantee that with this mechanism the two-way power supply can not connect simultaneously, and the safety when guaranteeing the two-way power source conversion.
The two-way power supply all has separately independently arc-control device, and it is opposite that the both sides moving contact is arranged to the folding direction, and the electric arc that produces when can allow each comfortable break-make reduces the influence of electric arc to two lateral circuits to the full extent from farthest.Therefore arc-control device is arranged on the dual-side of base plate, and dispels the heat to switch external.In the switch of big current class, must be provided with special arcing contact, close afterwards earlier and divide, not damaged by electric arc with the protection main contact.
Because the DC power supply arc extinguishing is more difficult, among the present invention, special in the middle of direct-flow input end and dc output end, be in series with many group dynamic/static contacts, all moving contacts are driven by same main shaft, connect simultaneously and disjunction with all fixed contacts, and this way can be divided into electric current multistage and carry out arc extinguishing, can improve arc quenching effect greatly, make switch have higher electric property.
The invention is characterized in that in automatic change-over two covers independently input and lead-out terminal are arranged, alternating current-direct current can insert use simultaneously.
Described in the middle of direct-flow input end and dc output end, be in series with many group dynamic/static contacts, all moving contacts are driven by same main shaft, connect simultaneously and disjunction with all fixed contacts.
The invention has the advantages that to be provided with two covers independently input and lead-out terminal, a cover is suitable for the break-make of AC power, the another set of break-make that is suitable for DC power supply, and reliable isolation is carried out in the centre, and guarantees that two road power supplys can not connect simultaneously; Have one the tunnel to be alternating current and another road when being direct current at the two-way power supply, can carry out conversion between the two-way heterogeneity power supply with it.Use in extensive range, energy-conserving and environment-protective, easy for operation flexible, have bigger economic benefit and social benefit, be beneficial to popularization.
