Abstract
The utility model relates to an overhauling device at a connecting point of an electrical device, in particular to a clamp for heating treatment at the connecting point of a high voltage device. The clamp is characterized in that a clamping plate which can move up and down is arranged in an upper plate and a lower plate of a clamp body with a 'C'-shaped section, and the clamping plate is parallel to the upper plate and the lower plate which are parallel; the lower part of the clamping plate can be rotatably connected with a bolt which penetrates through a bolt hole on the lower plate of the clamp body; and the lower end of the bolt is provided with a device which is used for rotating the bolt. When an aluminium bar which is connected with the high voltage device radiates seriously due to looseness, the clamp of the technical scheme can be adopted to clamp the connecting point of the aluminium bar tightly and temporarily so as to guarantee the safe running of a worker, a power grid and a device. An experiment shows that the temperature of the connecting point before urgent treatment is 95 DEG C to 100 DEG C, the temperature after treatment is 42 DEG C to 48 DEG C, and the effect is obvious. The clamp has the characteristics of simple structure, convenient use, good effect, repeated use and the like.
Description
Technical field
The utility model relates to a kind of apparatus for examination and repair of electric equipment tie point, and anchor clamps are handled in particularly a kind of high-tension apparatus tie point heating.
Background technology
When the high-voltage transforming station equipment connects aluminium row because of loosening serious heating, be the safety of assurance personnel, electrical network and equipment, must carry out emergency treatment to hidden danger equipment or zone; In case because a variety of causes causes equipment aluminium row junction bolt looseness, and then heating, aggravation along with the continuing of heating, the order of severity, can form hidden danger to personnel and device security, heat generating spot such as untimely elimination will cause service life of equipment to shorten, and plant machinery intensity reduces, even cause full station decompression and device damage, have a strong impact on power supply safety.Current, the method for emergency action is confined to tagmeme and rations the power supply and shut off power in emergency, and above method has caused serious economy loss to the user, even caused the civil order confusion when guaranteeing user, electrical network and device security, produces bad social influence.
Summary of the invention
The purpose of this utility model is the defective that overcomes prior art, provides a kind of when guaranteeing personnel, device security and not carrying out accident interruption, and anchor clamps are handled in the high-tension apparatus tie point heating of temporarily handling.
Technical scheme for achieving the above object is: anchor clamps are handled in a kind of high-tension apparatus tie point heating, it is characterized in that in up and down two parallel-plates of cross section, being equipped with and parallel clamping plate moving up and down of two parallel-plates up and down for the clamp body of " C " shape, the rotatable connection of following and bolt of clamping plate, bolt passes the bolt hole on the clamp body lower plate, is useful on the device of swivel bolt in the lower end of bolt.
The device that above-mentioned bolt lower end is used for swivel bolt is to be installed in the bearing pin of bolt lower end and bolt axis normal or the hexagon body of opening in the bolt lower end.
Arrange because of loosening serious adstante febre when the aluminium that is connected with high-tension apparatus, can adopt the tie point of the anchor clamps of the technical program, clamp, temporarily to guarantee the safe operation of staff, electrical network and equipment to aluminium row.During use, can these anchor clamps be installed on the tie point, drive clamping plate by handle tie point is closely contacted by this folder of long handle insulated pliers.Show that by experiment the temperature before the emergency treatment of junction is at 95-100 ℃, the temperature after the processing is 42-48 ℃, and positive effect is just arranged.Characteristics such as it is simple in structure, easy to use, effective, reusable that these anchor clamps have.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is the upward view of the utility model accompanying drawing 1.
Embodiment
As shown in Figure 1, be equipped with two parallel-plates are parallel up and down in two parallel-plates up and down of cross section for the clamp body 1 of " C " shape, and clamping plate 2 moving up and down, the lower plane of clamping plate 2 and 3 rotatable connections of bolt, on the lower plate of clamp body 1, have one with the bolt hole of bolt matching, bolt passing through bolt hole is equipped with the hexagon body that the bearing pin 4 that is used to rotate maybe can make the bolt rotation in the bolt lower end.
