Abstract
A safety energy-saving device for no-load shutdown of electric welding machine pertains to the art of technical control of electric welding machines. The technical problem to be solved is to provide an energy-saving device to communicate with the power supply of the electric welding machine rapidly, conveniently and flexibly. The technical characteristics are that: the anode (Y1) of one end of a two-way silicon control (KG) is connected with one end of the AC power while resistances (R1, R2) and a mechanical switch (K) are arranged in series between the anode (Y2) of the other end and the other end of the AC power; the loop (L) of an AC contactor (JLQ) is arranged in series between the control terminal (G) of the two-way silicon control and the other end of the AC power; and two pairs of contacting points (CD) of the AC contactor are respectively connected with the AC power and the primary loop of a transformer (B) of the electric welding machine. The utility model is characterized in convenient, rapid and flexible control on the power of electric welding machine, plus simple circuit structure, low production cost, easy and reliable operation.
Description
Technical field:
The utility model relates to a kind of control device of electric welding machine, particularly a kind ofly is used for the safety electricity-saving device that electric welder no-load promptly stops.
Background technology:
As everyone knows, electric welding machine is a kind of electric equipment that carries out Metal Material Welding.Present employed electric welding machine at first will be switched on to electric welding machine, and then weld before being welded.Because electric welding machine in use is the batch (-type) operation, therefore, generally speaking in most of times, electric welding machine is in the no-load running state after energising, and this moment unloaded electric welding machine because of with power connection, so can consume certain electric energy, the time of electric welder no-load operation is long more, and its meritorious electric energy that consumes is then many more.
Summary of the invention:
Technical problem to be solved in the utility model is: a kind of safety electricity-saving device that electric welder no-load promptly stops that is used for is provided, it can connect the power supply of electric welding machine fast, easily and flexibly when electric welding machine need weld, when electric welding machine does not need to weld, can close the power supply of electric welding machine in time, easily, thereby reach the purpose that reduces energy consumption, electrical energy saving.Its technical scheme is: a kind ofly be used for the safety electricity-saving device that electric welder no-load promptly stops, form by A.C. contactor, bidirectional triode thyristor, resistance and mechanical switch, it is characterized in that: the anode of bidirectional triode thyristor one end and an end of AC power join, be in series with resistance and mechanical switch between the anode of its other end and the other end AC power, be connected in series the coil of A.C. contactor between the control utmost point of bidirectional triode thyristor and the other end AC power, two pairs of contacts of A.C. contactor join with the transformer of AC power and electric welding machine respectively.Described mechanical switch places on the handle of electric welding machine welding gun.Its technique effect is: because the power supply of the transformer of electric welding machine is placed under the control of this battery saving arrangement, and just the mechanical switch of the transformer power supply switching of electric welding machine places on the handle of welding gun, therefore, can start or close the power supply of electric welding machine easily and fast, neatly.When needs weld, as long as press mechanical switch on the welding gun handle, can connect the power supply of electric welding machine, make it work; When the needs standby, as long as also press mechanical switch on the welding gun handle, can cut off the power supply of electric welding machine, realize reducing the purpose of energy consumption, electrical energy saving.In addition, the utility model circuit structure is simple, and cost is cheap, and handling safety is reliable.
Description of drawings:
Fig. 1 is the utility model electrical schematic diagram.
Embodiment:
As shown in Figure 1, the anode Y1 of bidirectional triode thyristor KG one end and an end of AC power join, be in series with resistance R 1, R2 and mechanical switch K between the anode Y2 of its other end and the other end AC power, be connected in series the coil L of A.C. contactor JLQ between the control utmost point G of bidirectional triode thyristor and the other end AC power, two couples of contact CD of A.C. contactor join with the transformer B primary coil of AC power and electric welding machine respectively.
For the ease of control, mechanical switch K places (not shown) on the handle of electric welding machine welding gun.
Its course of work: when mechanical switch K is in the disconnecting state, the coil L of A.C. contactor JLQ outage, its two pairs of contacts are not closed, the transformer B primary coil non-transformer input of electric welding machine, the electric welding machine outage is not worked; When mechanical switch K is in closure state, the coil L of A.C. contactor JLQ energising, its two pairs of closings of contact insert the transformer B primary coil of electric welding machine with power supply, and the electric welding machine energising can be welded.
Claims (2)
1, a kind ofly be used for the safety electricity-saving device that electric welder no-load promptly stops, by A.C. contactor, bidirectional triode thyristor, resistance and mechanical switch are formed, it is characterized in that: the anode (Y1) of bidirectional triode thyristor (KG) end joins with an end of AC power, be in series with resistance (R1 between anode of its other end (Y2) and the other end AC power, R2) and mechanical switch (K), be connected in series the coil (L) of A.C. contactor (JLQ) between the control utmost point (G) of bidirectional triode thyristor and the other end AC power, two pairs of contacts (CD) of A.C. contactor join with transformer (B) primary coil of AC power and electric welding machine respectively.
