Abstract
The utility model relates to a high-voltage appliance, in particular to a dynamic contact of a high-voltage vacuum breaker and a static contact matched with the dynamic contact and located in a high-voltage switch cabinet. The dynamic contact comprises a touch arm, as well as a large tulip contact and a small tulip contact that are concentrically mounted on the touch arm, wherein the small tulip contact is mounted in the inner ring of the large tulip contact. The dynamic contact and the static contact have the advantages of reasonable design and improved current carrying capability without improving the volumes of the dynamic contact and the static contact. Additionally, the dynamic contact and the static contact can occlude each other firmly at any time, and normal match and separation of the two contacts can be achieved.
Description
Technical field
The utility model relates to a kind of High-Voltage Electrical Appliances, specifically relates to the moving contact of high-pressure vacuum breaker and the fixed contact that is positioned at high-tension switch cabinet that cooperates with moving contact.
Background technology
Cooperate normally the fingertip and the spring by Mume flower contact of the moving contact of existing high-pressure vacuum breaker and fixed contact are engaged on the single fixed contact single moving contact, require each contact point stressed evenly cooperating between moving contact and the fixed contact, electric conductivity is efficiently arranged, and moving contact and fixed contact volume again can not be excessive simultaneously.Original moving contact and fixed contact, moving contact is single Mume flower contact, fixed contact is a cylinder, moving contact interlock fixed contact, owing to moving contact and fixed contact are combined with reasons such as the divide-shut brake vibration of sum of errors circuit breaker is bigger, discontinuity appears in the interlock meeting between moving contact and the fixed contact, and contact area reduces, cause the bearing capacity of electric current to reduce, the too high phenomenon of temperature rise can appear in the part.
Summary of the invention
Therefore, the purpose of this utility model is to provide a kind of and does not increase the dynamic/static contact external volume and can increase the contact area of dynamic/static contact joint portion and improve the moving contact of the high-pressure vacuum breaker of loaded current ability between dynamic/static contact and the fixed contact of the high-tension switch cabinet that is mated.
To achieve these goals, the utility model has carried out following improvement to moving contact and fixed contact respectively:
A kind of moving contact of high-pressure vacuum breaker comprises contact arm and the concentric large and small Mume flower contact that is installed on the contact arm, and little Mume flower contact is located at big Mume flower contact inner ring.
For can and above-mentioned moving contact be used, fixed contact is done corresponding following change, in a hollow cylindrical fixed contact body, be provided with the interior fixed contact concentric with it, both form a pair structure of contact terminal.
In order not increase the propulsive force of moving contact, make the moving contact can be normally and the fixed contact interlock, can be designed to stretch out big Mume flower contact end face to little Mume flower contact end face.Accordingly interior fixed contact end face is designed to contract in fixed contact body end face inboard.Fixed contact in the engagement earlier of so little Mume flower contact.
The utility model is reasonable in design, neither increases the volume of existing moving contact and fixed contact, has improved moving contact and the fixed contact bearing capacity to electric current again, and guarantees that both at any time can both firm interlock, the normal cooperation that can realize both again with separate.

Fig. 4 is the axial section structural representation sketch of moving contact and fixed contact.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
In conjunction with Fig. 1 to Fig. 4, a kind of moving contact 1 of high-pressure vacuum breaker comprises contact arm 2 and the big Mume flower contact 3 that is installed on the contact arm, and described big Mume flower contact 3 inner rings are provided with a little Mume flower contact 4 concentric with it, and little Mume flower contact 4 is installed on the contact arm 2 equally.
A kind of fixed contact 5 that can be used with above-mentioned moving contact 1 comprises columniform hollow fixed contact body 6, and described fixed contact body 6 inner rings are provided with the interior fixed contact 7 concentric with it.
Described little Mume flower contact end face stretches out big Mume flower contact end face, and described interior stationary contact reduction of area is in fixed contact body end face inboard.Like this when moving contact is connected with fixed contact, little Mume flower contact and the interlock of interior fixed contact elder generation.
Claims (4)
1, a kind of moving contact of high-pressure vacuum breaker comprises contact arm and the Mume flower contact that is installed on the contact arm, and it is characterized in that: described Mume flower contact inner ring is provided with a little Mume flower contact concentric with it, and little Mume flower contact is installed on the contact arm equally.
2, according to the moving contact of the described high-pressure vacuum breaker of claim 1, it is characterized in that: described little Mume flower contact end face stretches out the Mume flower contact end face.
