Abstract
The utility model discloses an automatic isolation device of a high-voltage isolation switch, which comprises an isolation board, guide rails, bearings, a rocker and a connecting rod, wherein the guide rails are arranged at the left end and the right end in a cabinet, the bearings which are respectively at the left end and the right end of the isolation board are arranged in the guide rails, one end of the rocker is hinged at the front door of the cabinet, the other end of the rocker is mutually hinged with one end of the connecting rod, and the other end of the connecting rod is hinged on the isolation board. When the front door is opened, the isolation board is driven by the rocker and the connecting rod to move into the fracture of a high-voltage isolation switch along the guide rails. When the front door is closed, the isolation board is driven by the rocker and the connecting rod to move out the fracture of the high-voltage isolation switch along the guide rails. When the front door is fully closed, the isolation board resets to the original position. The automatic isolation device is free from manual inserting, is convenient to operate, is safe to use, simultaneously, improves the protection level IP2X of the cabinet, and is applicable for being as isolation equipment in high-voltage power distribution complete equipment and a high-voltage isolation switch assembled by control equipment.
Description
Technical field
The utility model relates to the servicing unit of the equipped high voltage isolator of a kind of high voltage power distribution complete set of equipments and control appliance, relates in particular to a kind of spacer assembly of high voltage isolator.
Background technology
At present, when the big electric current cabinet of the XGN2 type of the high voltage power distribution control appliance of GN22 type high voltage isolator such as 4000A is equipped with in maintenance, the plate that is used to separate the visible fracture of GN22 type high voltage isolator adopts manual operation to carry out, and promptly by operating personnel plate is injected in the cabinet along the slotted hole on the door.Owing to manually insert plate, very inconvenient in the operation, operating personnel carry out under the charged situation of fixed contact or the first end of movable contact simultaneously, operate dangerously, and open slotted hole and also reduced the original degree of protection IP2X of cabinet on the Qianmen.
The utility model content
The purpose of this utility model is to provide a kind of automatic spacer assembly of high voltage isolator easy to operate, safe in utilization.
The purpose of this utility model is achieved by the following technical programs:
The automatic spacer assembly of a kind of high voltage isolator that the utility model provides comprises division board; Comprise guide rail, bearing, rocking bar and connecting rod in addition, described guide rail is installed in the approaching position of isolating switch in the cabinet, and the described bearing of holding about division board that is installed in is arranged in the guide rail; One end of described rocking bar is hinged on the Qianmen of cabinet, and an end of its other end and described connecting rod is hinged, and the other end of connecting rod is hinged on the division board.Be arranged in the guide rail owing to be installed in the bearing of division board left end and right-hand member, so division board can move along guide rail.When open at the Qianmen of cabinet, drive division board moves into high voltage isolator along guide rail fracture by rocking bar and connecting rod; When closing the Qianmen, drive division board withdraws from high voltage isolator along guide rail fracture by rocking bar and connecting rod.When the Qianmen was shut fully, division board was got back to initial position, can not influence the operation of high voltage isolator.
For improving the accuracy that division board moves, the shift position of restriction division board, the Qianmen of cabinet described in the utility model are equipped with the qualification Qianmen and are the stop that angle is opened; Position near the Qianmen on the inherent division board moving direction of cabinet is vertically arranged with the division board locating part, and described division board locating part is fixed on the cabinet by supporting bracket.When an angle is opened at the rotation Qianmen, division board moves into the fracture of high voltage isolator, stop restriction Qianmen on the Qianmen is rotated further, and the division board of division board locating part restriction simultaneously continues to move, thereby guarantees that division board accurately is positioned at the fracture site place of high voltage isolator.The angle that open at Qianmen described in the utility model is 90 °.
For improving stability of transmission, division board can steadily be moved, connecting rod described in the utility model is hinged on the described division board locating part by pivot pin.
Bearing described in the utility model is installed in the left end and the right-hand member of described division board by angle steel, be beneficial to division board move and firm.
For further strengthening the steadiness of division board, on the division board described in the utility model stiffener is installed.
The utlity model has following beneficial effect: when opening or closing the cabinet Qianmen, can automatically division board be moved into or withdraw from the fracture of high voltage isolator, need not manual insertion, flexible operation, convenience, guarantee operating personnel's personal safety better, also improved the degree of protection IP2X of cabinet simultaneously.
Description of drawings
Below in conjunction with embodiment and accompanying drawing the utility model is described in further detail:
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the right view during door closure state before Fig. 1;
Fig. 3 is the transmission principle schematic diagram of the utility model embodiment.
Embodiment
Fig. 1～Figure 3 shows that embodiment of the present utility model, comprise division board 7, guide rail 6 and 6 ', bearing 3 and 3 ', rocking bar 14, connecting rod 11, channel-section steel, angle steel 5 and 5 ', supporting bracket 9, stiffener 8 and stop 16.As shown in Figure 1, left part in the cabinet 1 and right part be installed with respectively two pairs of channel-section steels 2 and 2 ', two guide rails 6 and 6 ' respectively be welded on channel-section steel 2 and 2 ' on; The two pairs of bearings 3 and 3 ' respectively are by angle steel 5 and 5 ' and pivot pin 4 and 4 ' be installed in the left end and the right-hand member of division board 7, the guide rail 6 and 6 of and two pairs of bearings 3 and 3 ' lay respectively at left part and right part in the cabinet 1 ' in.One end of rocking bar 14 is hinged on the top at cabinet Qianmen 15, and its other end is hinged by an end of pivot pin 13 and connecting rod 11, and the other end of connecting rod 11 is hinged on the bottom of division board 7.Position near Qianmen 15 on cabinet 1 inherent division board 7 moving directions is vertically arranged with a channel-section steel as division board locating part 10, and division board locating part 10 is fixed on the cabinet 1 by supporting bracket 9; Connecting rod 11 is hinged on the division board locating part 10 by pivot pin 12.Two sides at division board 7 also is respectively arranged with stiffener 8.As shown in Figure 2,15 upper end is provided with a stop 16 at the Qianmen, and automatic spacing when being opened to 90 ° is rotated at restriction Qianmen 15 in 0～90 °.
