In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is, the automatic grounding apparatus of a kind of high pressure, comprise: earth rod, box body, and be located at box body interior electromagnet, transformer and earth rod fastener, and described transformer and electromagnet are electrically connected, and described earth rod fastener is fixedlyed connected with electromagnet; Cover on the described box body and offer bayonet socket, an end of described earth rod is fixed in the earth rod fastener, and its process bayonet socket of the other end of earth rod also stretches out box body.The action of described transformer energising rear drive electromagnet, electromagnet drives the earth rod fastener action that is attached thereto, and then drives the earth rod action, thereby realizes automatic ground connection.
Further, described electromagnet is rotary electric magnet, realizes rotatablely moving by the steel ball in the chute of being located at rotary electric magnet, and its anglec of rotation can choosing between several years and 90 degree.Further, described earth rod fastener is provided with in order to the fixing side plate of usefulness, and this earth rod fastener is fixedly attached to a side of rotary electric magnet by side plate.By covering the cooperations such as bayonet socket of offering on above-mentioned rotary electric magnet, earth rod fastener and the box body, be grounded the control of the anglec of rotation of rod.
Further, described box body on to cover the bayonet socket of offering be the strip bayonet socket.
Further, described earth rod is the irony earth rod.
The automatic grounding apparatus of high pressure of the present utility model cooperates with high-tension apparatus, can the automatic grounding apparatus of high pressure be set by high-tension apparatus and remove the condition of ground connection, and when all conditions that arranges satisfied, the automatic grounding apparatus of high pressure just can be removed automatic ground connection; Otherwise high-pressure side is ground connection all the time; voltage can't rise; in the process of Hi-pot test simultaneously; in case break down or there is the people to be strayed into test zone; equipment will carry out ground protection to high-pressure side rapidly; guarantee the fail safe of high-tension apparatus, and the fail safe of high voltage test, reliability, avoided Hi-pot test equipment because not having ground connection and cause device damage even cause the generation of human casualty accident etc. situation.

Embodiment
Now with embodiment the utility model is further specified by reference to the accompanying drawings.
As a specific embodiment, as Fig. 1-shown in Figure 4, the automatic grounding apparatus of a kind of high pressure of utility model, comprise: earth rod 1, box body 2, and be located at electromagnet 3, transformer 4 and earth rod fastener 5 in the box body 2, and described transformer 4 and electromagnet 3 are electrically connected, and described earth rod fastener 5 is fixedlyed connected with electromagnet 3.Offer bayonet socket 22 on the loam cake 21 of described box body 2, this bayonet socket 22 is the strip bayonet socket.One end of described earth rod 1 is fixed in the earth rod fastener 5, and its process bayonet socket 22 of the other end of earth rod 1 also stretches out box body 2.3 actions of described transformer 4 energising rear drive electromagnet, electromagnet 3 drives earth rod fastener 5 actions that are attached thereto, and then drives earth rod 1 action, thereby realizes automatic ground connection.
Wherein, described electromagnet 3 is rotary electric magnet, realizes rotatablely moving by the steel ball in the chute of being located at rotary electric magnet 3, and its anglec of rotation can choosing between several years and 90 degree.
In addition, described earth rod fastener 5 is provided with in order to the fixedly side plate 51 of usefulness and the draw-in groove 52 of holding earth rod, and this earth rod fastener 5 is fixedly attached to a side of rotary electric magnet by side plate 51.Cooperation between the bayonet socket of offering on the loam cake 21 by above-mentioned rotary electric magnet, earth rod fastener 5 and box body 2 22 is grounded the control of the anglec of rotation of rod 1.
In addition, above-mentioned earth rod is the irony earth rod, is used for the electric charge on the high-tension apparatus is discharged.
In addition, the earth rod fastener can be made angle-inserting type, is used for retaining on the doorway; Force operating personnel must pick up earth rod and just can enter withstand voltage chamber, prevent possible high-voltage residual-electricity life threatening; Force operating personnel must insert earth rod and just can begin voltage-withstand test, operating personnel are risen high voltage when preventing that earth rod from hanging over high-pressure side.
The utility model can be applicable on the various high-tension apparatuses, for example the testing high voltage circuit breaker industrial frequency withstand voltage equipment, power frequency high voltage pilot system, general circuit breaker is 10KV-100KV, belong to high-risk equipment, for ensureing the fail safe of withstand voltage test, the automatic grounding apparatus of high pressure of the present utility model is connected with it by cable, and when all conditions satisfied, the automatic grounding apparatus of high pressure just can be removed automatic ground connection; Otherwise high-pressure side is ground connection all the time, and voltage can't rise.In addition, in the voltage-withstand test process, any one condition is destroyed, and high pressure output stops automatically, automatic earthing device closure, high-pressure side ground connection.The utility model has improved fail safe, the reliability of withstand voltage test.
