Abstract
The utility model discloses a knife-blade closure compressing mechanism used on an indoor high voltage isolating switch in the electric power distribution system. A magnetic lock plate(4) is fixed on a side surface of a knife blade(2) and a sliding bush thrust mechanism is fixed between the left and the right knife blades(2); the sliding bush thrust mechanism comes into being through the arrangement of a sliding bush(6) a the left and the right knife blades(2), with the sliding bush(6) provided from the center to the two sides in turn with a sliding shaft(8), a steel ball(7) and a mandril(5); the sliding shaft(8) is provided with a groove matched with the excircle of the steel ball(7) and the mandril(5) and the magnetic lock plate(4) form a reciprocity surface. As an internal lever is substituted for the external spring mechanism, the knife-blade closure compressing mechanism of the utility model is compacted in structure and occupies small area, and the compressing area is large and the operational moment is small.
Description
Technical field
The utility model belongs to electrical technology field, particularly a kind of indoor high-voltage isolating switch contact knife combined floodgate hold-down mechanism.
Background technology
Indoor high-voltage isolating switch is to isolate, connect, changing the device of getting in touch between electrified body and the electrical equipment under the non-loaded state of circuit in the electrical power distribution system.Isolate when contact knife closes a floodgate and use hold-down mechanism that contact knife is applied normal pressure, allow contact knife and contact better contact to reduce loop resistance.Existing isolating switch such as GN19 series, its hold-down mechanism is realized like this: magnetic padlock plate two ends are fixed in the contact knife U type groove by bolt and boss, and spring is by being bolted to the magnetic padlock plate outside.When contact knife closed a floodgate, length of spring compressed was exerted pressure to contact knife by the magnetic padlock plate.This hold-down mechanism pressure contact-making surface is little, and it is big to take up room, and operational torque is big.
The utility model content
The purpose of this utility model is that a kind of pressure contact-making surface of design is big, and it is little to take up room, and the little indoor high-voltage isolating switch contact knife combined floodgate hold-down mechanism of operational torque.
The lever thrust mechanism replaced the outer spring pressure mechanism in the utility model was achieved in that and adopts, with the magnetic padlock plate by being bolted to the side of contact knife, between the contact knife of the left and right sides, fix a sliding sleeve thrust structure, be set with sliding axle, steel ball and push rod successively from middle mind-set both sides in the sliding sleeve, sliding axle is provided with the groove that is complementary with the steel ball cylindrical, and push rod and magnetic padlock plate form interaction face.When isolating switch closed a floodgate, sliding axle moved downwards and forces steel ball to separate with the groove of sliding axle and motion laterally, promoted push rod and acted on the magnetic padlock plate, and magnetic padlock plate and bolt form lever, was pressed on the contact knife after the thrust of push rod is amplified.
The switch touching knife combined floodgate hold-down mechanism compact conformation that the utility model provides, it is little to take up room, and the pressure contact-making surface is big, and operational torque is little.
Description of drawings
Fig. 1 is the structural representation of existing GN19 switch touching knife combined floodgate hold-down mechanism;
Fig. 2 is the structural representation of an embodiment of the utility model switch touching knife combined floodgate hold-down mechanism.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Among the figure: 1, contact 2, touch 3, bolt 4, magnetic padlock plate 5, push rod 6, sliding sleeve 7, steel ball 8, sliding axle 9, spring
In the embodiment shown in Figure 2, about two magnetic padlock plates 4 be fixed in the U type groove of contact knife 2 sides by bolt 3, between left and right sides contact knife 2, be fixed with a sliding sleeve 6, be set with sliding axle 8, steel ball 7 and push rod 5 successively from middle mind-set both sides in the sliding sleeve 6, the groove that is complementary with steel ball 7 cylindricals is arranged on the sliding axle 8, and push rod 5 forms interaction face with magnetic padlock plate 4.
When isolating switch closed a floodgate, sliding axle 8 moved downward and forces steel ball 7 to separate laterally motion with the groove of sliding axle 8, push rod 5 under the effect of steel ball 7 to magnetic padlock plate 4 terminal applied thrusts.4 leverages of magnetic padlock plate are pressed on the contact knife 2 after the thrust increase with push rod 5 and form contact pressure.This cover compresses device and replaces the outer spring pressure mechanism with interior lever thrust mechanism, and compact conformation has reduced operational torque and taken up room.
Claims (1)
