Abstract
The utility model provides a zero-load electricity saving device for an electric welding machine. When the electric welding machine does not carry out welding work, a welder switches off a switch arranged on a welding gun, and a power supply return of the electric welding machine is switched off. When the electric welding machine carries out welding work, the welder holds the welding gun by a hand and switches on the switch simultaneously so that the power supply return is switched on, and purposes of intermittent work and electricity saving can be achieved. The switch, a coil of an alternating current contactor and a low-voltage secondary stage of an alternating current transformer are connected in series into a return, a primary stage of the transformer is connected to a power supply of the electric welding machine in parallel, and a contact of the alternating current contactor is connected to a power supply input circuit of the electric welding machine.
Description
The utility model relates to electric welding machine, particularly a kind of loaded energy-saving device of electric welding machine.
Electric welding machine all is an intermittently used generally, has the considerable time to be in unloaded power consumption state, and electricity wasting also is unsafe factor on the other hand concerning the welder on the one hand.
The utility model provides a kind of electric welder no-load battery saving arrangement, and when electric welding machine did not carry out welding job, the welder disconnected the switch that is provided with on the welding gun, and the electric power loop of electric welding machine is disconnected; When welding, the welder holds welding gun and connects the electric power loop connection that switch makes electric welding machine simultaneously, reaches the purpose of discontinuous operation economize on electricity.
The technical solution of the utility model is that a switch is set on quick-fried welding gun, the low-voltage secondary of this switch and ac contactor coil and AC transformer conspires to create a loop, transformer elementary is parallel on the power supply of electric welding machine, and the contact of A.C. contactor is connected in the power supply input circuit of electric welding machine.
Transformer secondary output is 36V, secondaryly is provided with tap, selects tap corresponding with primary 380V or 220V by a switch.
Drawings and Examples
Fig. 1 is a fundamental diagram of the present utility model.
JB is an electric welding machine among the figure, and 1 is welding gun, and 2 is welding rod.Connect power supply, battery saving arrangement is started working, and when exchanging 380V voltage through the B transformation, obtains exchanging the safe voltage of 36V, and 36V voltage is through tap 1 change-over switch K
1Arrive gauge tap K with A.C. contactor CJ
2, Push switch K
2Just can control the adhesive of CJ contact and separate, reach the energising and the outage of electric welding machine.
When voltage is alternating current 220V, obtain the 36V safe voltage equally through the B transformation, 36V voltage is through tap 2 change-over switch K
1Arrive gauge tap K with CJ
2, Push switch K
2Also can control the adhesive of CJ contact and separate, reach the energising and the outage of electric welding machine.
The transformer B that this welding machine battery saving arrangement is used, primary coil maintains static.Secondary coil utilizes tap, when elementary when being 380V voltage, and secondary 1,3 output 36V safe voltages.When being 220V, secondary 2,3 also export the 36V safe voltage when elementary.K
1Be change-over switch, CJ selects the A.C. contactor of CJ10-20 type for use, and the pull-in winding voltage of contactor is 36V, and three groups of contacts of contactor are wanted in parallel and used.
This battery saving arrangement is a design switch on soldering turret cleverly, can be arranged on the cover, no matter how soldering turret is placed, can not make switch produce misoperation.Utilize spring force, make switch be in the state (normally closed switch) of pass all the time.When needs weld, just press the switch on the soldering turret, the welding machine energising just can be welded.
Transformer in this battery saving arrangement and contactor and K
1Can be produced in the electric welding machine K
1Be located on the casing.Welding gun can design a kind of welding gun of new belt switch, and the control line of battery saving arrangement is not placed on the cable outside, can be integrated with the leader cable line, and wrap up with rubber the outside, so just can protect control line well, feels it is two cables all the time to the people.
This battery saving arrangement has kept every performance of former welding machine through using proof, and working stability, and power savings is remarkable, and is safe in utilization, rational in infrastructure, and durable is convenient to maintenance, and it is applicable to the AC and DC electric welding machine of different capabilities.
Claims (2)
1. the loaded energy-saving device of electric welding machine, it is characterized in that on welding gun, being provided with a switch, the low-voltage secondary of this switch and ac contactor coil and AC transformer conspires to create a loop, transformer elementary is parallel on the power supply of electric welding machine, and the contact of A.C. contactor is connected in the power supply input circuit of electric welding machine.
2. the loaded energy-saving device of electric welding machine according to claim 1 is characterized in that transformer secondary output is 36V, secondaryly is provided with tap, selects tap corresponding with primary 380V or 220V by a switch.
