The controller is simple in structure, elements inside the controller are cheap in price and can be rapidly replaced even if damaged, experimental period is unaffected, and the controller is portable. The conversion circuit realizes conversion control for the alternating current and the direct current, and the problem that an original mechanical characteristic testing instrument can only control isolated grounding mechanisms using direct current is solved.
Description
Technical field
The utility model relates to a kind of controller.
Background technology
Isolate earthing mechanism and in maintenance combination of gases electrical equipment process, play the ground protection effect, isolate earthing device and have three electric signal input ends, be respectively common port input, combined floodgate input and separating brake input.After the switching signal input, the motor of isolating in the earthing mechanism just changes control pull rod and contact closure, whole grounded circuit conducting.After the sub-gate signal input, the motor counter-rotating, pull bar and contact break off, and grounded circuit breaks off.At present, that isolates that the controller of ground structure uses is the testing mechanical characteristic appearance, but this kind tester costs an arm and a leg, and causes damage easily as if operate miss, has increased the cost of enterprise.
The utility model content
The purpose of the utility model provides a kind of isolation earthing mechanism controller simple in structure, lower-cost.
To achieve these goals; Adopt following technical scheme: a kind of isolation earthing mechanism controller; It is characterized in that: said controller comprises all with the live wire of alternating current and zero line link to each other and exchanges air switch and convert alternating current into galvanic change-over circuit; Be connected with the direct current air switch after the change-over circuit, exchange air switch and be connected with AC switch through lead afterwards, be connected with the direct current change over switch through lead after the direct current air switch; One end of AC switch and direct current change over switch is connected to the common port of controller respectively, and the other end is connected to the combined floodgate output and the separating brake output of controller through combined floodgate switch and separating brake switch.
As further optimization, discern the AC and DC signal for ease, be connected with the interchange indicator light between said interchange air switch and the AC switch, be connected with the direct current indicator light between direct current air switch and the direct current change over switch.
The utility model is simple in structure, and inner element low price even component wear can be changed fast, does not influence experimental period, and is easy to carry.Change-over circuit has been realized the conversion and control of AC and DC, has solved original testing mechanical characteristic appearance and can only control the problem of using galvanic isolation earthing mechanism.
Description of drawings
Fig. 1 is the circuit diagram of the utility model.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is further specified.
As shown in Figure 1; A kind of isolation earthing mechanism controller; Comprise all with the live wire of alternating current and zero line link to each other and exchange air switch 1 and convert alternating current into galvanic change-over circuit; Be connected with direct current air switch 2 after the change-over circuit, exchange air switch and be connected with AC switch 5 through lead afterwards, be connected with direct current change over switch 6 through lead after the direct current air switch; Exchange and be connected with interchange indicator light 3 between air switch 1 and the AC switch 5, be connected with direct current indicator light 4 between direct current air switch 2 and the direct current change over switch 6.One end of AC switch and direct current change over switch is connected to the common port of controller respectively, and the other end is connected to the combined floodgate output and the separating brake output of controller through combined floodgate switch 7 and separating brake switch 8.
During use; The zero line and the live wire of alternating current are inserted; Make direct current air switch and direct current change over switch keep off-state, close the interchange air switch, it is bright to exchange indicator light; And then close AC switch, just can control the rotating of the isolation earthing mechanism motor internal of far-end then through combined floodgate switch and separating brake switch.
Interchange air switch and AC switch are broken off in same operation, and closed direct current air switch and direct current change over switch just can conveniently use direct current to control isolating the inner motor of earthing mechanism.
Claims (2)
1. isolate the earthing mechanism controller for one kind; It is characterized in that: said controller comprises all with the live wire of alternating current and zero line link to each other and exchanges air switch and convert alternating current into galvanic change-over circuit; Be connected with the direct current air switch after the change-over circuit; Be connected with AC switch through lead after exchanging air switch; Be connected with the direct current change over switch through lead after the direct current air switch, an end of AC switch and direct current change over switch is connected to the common port of controller respectively, and the other end is connected to the combined floodgate output and the separating brake output of controller through combined floodgate switch and separating brake switch.
2. isolation earthing mechanism controller as claimed in claim 1 is characterized in that: be connected with the interchange indicator light between said interchange air switch and the AC switch, be connected with the direct current indicator light between direct current air switch and the direct current change over switch.
