Description
Technical field
The utility model relates to the high-voltage electrical apparatus element, relates in particular to the structure of high-pressure vacuum breaker.
Background technology
In the application in high-tension electricity field, high-pressure vacuum breaker is the switch of the vacuum degree of control piper or certain enclosure space, and for pure mechanical deformation causes the sensitive switch action, main effect is the electric elements that cut off big electric current.
Existing high-pressure vacuum breaker generally comprise the vacuum interrupter that is installed on the conducting bracket; The upper end of vacuum interrupter is the stiff end that has connected fixed contact; The lower end of vacuum interrupter is for connecting the operating side of moving contact; The operating side is connected with drive disk assemblies such as insulation blanket studs, control each phase contact deciliter.For divide-shut brake synchronism, the divide-shut brake speed of adjusting each phase contact, open apart from indexs such as strokes; Traditional method is that the insulation blanket stud of operating side is pulled down from moving contact, through screw-in and its length of back-out adjustment of screw thread, to reach the purpose of regulating corresponding operational factor; Because the insulation blanket stud that is connected with moving contact is installed in the bottom of device; And near driving shaft, the operating space is narrow and small, thereby makes its adjustment process very complicated, loaded down with trivial details.
Therefore, there is a kind of high-pressure vacuum breaker that it is improved, increases the adjustment piece through the fixed contact position; The center that the adjustment piece is installed on conductive plate has in the screwed hole, and the adjustment piece is connected through securing member with the fixed contact upper end of vacuum interrupter to be fixed, and adjusts fixed contact through the adjustment piece; Because the first end of stationary contact carries out; And less relatively at these position zero parts, the operating space is bigger, needs the part of dismounting also less.
Yet still there is defective in this high-pressure vacuum breaker, though the parts of the first end of stationary contact are less relatively, the operating space is bigger, needs the part of dismounting also less,, still to carry out the part dismounting during adjustment, inconvenience still in the operation.
The utility model content
Therefore; The utility model is to the weak point of existing high-pressure vacuum breaker; A kind of improved high-pressure vacuum breaker structure is proposed, position that can the rapid adjustment fixed contact, thereby realize contact divide-shut brake synchronism, divide-shut brake speed, open quick and convenient adjustment apart from indexs such as strokes.
The technical scheme of the utility model is:
High-pressure vacuum breaker comprises:
One fixed contact is positioned at the housing upper end position, is arranged at the upper end of vacuum interrupter;
One moving contact is positioned at the housing lower end position, is arranged at the lower end of vacuum interrupter;
One vacuum interrupter is positioned at housing;
One conductive plate is arranged at above-mentioned fixed contact upper end, and is connected with the fixed contact conduction, and the conductive plate center is provided with a through hole;
One adjusting lever, adjusting lever one end is fixed in above-mentioned fixed contact, and runs through the through hole through the conductive plate center, and the other end of adjusting lever is established screw thread;
One adjustment nut is combined on the screw thread on the adjusting lever;
One insulating bar, an end is connected in above-mentioned moving contact, and the other end is connected in drive disk assembly, and power to the above-mentioned moving contact that transmits drive disk assembly through insulating bar moves;
An and housing.
The utility model adopts as above technical scheme; Existing high-pressure vacuum breaker structure is improved; Can realize adjusting the height of fixed contact through the adjustment nut of housing upper end; Thereby can be very convenient and the position of rapid adjustment fixed contact, thus realize contact divide-shut brake synchronism, divide-shut brake speed, open quick and convenient adjustment apart from indexs such as strokes, need not to dismantle too much parts again.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Combine accompanying drawing and embodiment that the utility model is further specified at present.
Consult shown in Figure 1ly, the high-pressure vacuum breaker of present embodiment comprises:
One fixed contact 1 is positioned at housing 8 upper end positions, is arranged at the upper end of vacuum interrupter 3;
One moving contact 2 is positioned at housing 8 lower end positions, is arranged at the lower end of vacuum interrupter 3;
One vacuum interrupter 3 is positioned at housing 8;
One conductive plate 4 is arranged at above-mentioned fixed contact 1 upper end, and is connected with fixed contact 2 conductions, and conductive plate 4 centers are provided with a through hole;
One adjusting lever 5, adjusting lever 5 one ends are fixed in above-mentioned fixed contact 1, and run through the through hole through conductive plate 4 centers, and the other end of adjusting lever 5 is established screw thread;
One adjustment nut 6 is combined on the screw thread on the adjusting lever 5;
One insulating bar, 7, one ends are connected in above-mentioned moving contact 2, and the other end is connected in drive disk assembly, and power to the above-mentioned moving contact 2 that transmits drive disk assembly through insulating bar 7 moves;
An and housing 8.
The high-pressure vacuum breaker of the utility model can realize adjusting the height of fixed contact 1 through the adjustment nut 6 of housing 8 upper ends; Thereby can be very convenient and the position of rapid adjustment fixed contact; Thereby realize contact divide-shut brake synchronism, divide-shut brake speed, open quick and convenient adjustment apart from indexs such as strokes, need not to dismantle too much parts again.
Although specifically show and introduced the utility model in conjunction with preferred embodiment; But the those skilled in the art should be understood that; In the spirit and scope of the utility model that does not break away from appended claims and limited; Can make various variations to the utility model in form with on the details, be the protection range of the utility model.
