The utility model discloses simple structure can guarantee that isolator's three-phase isolation blade can reliably be closed simultaneously, reduces equipment damage, improves the power supply possibility.
Description
Technical Field
The utility model belongs to the electrical equipment field, concretely relates to take isolator of spherical contact.
Background
Along with the improvement of the attention degree of a power distribution network, more and more 10kV vacuum column upper circuit breaker complete equipment is applied to an overhead line, and the complete equipment comprises a terminal, a circuit breaker, a three-phase linkage type isolating switch and a mutual inductor.
In the use process of nearly two years, the isolating switch in complete equipment in a power supply office is inconvenient to operate, the condition that the isolating blade is not closed well often occurs, and as one phase in the three-phase isolating blade is not closed in place, a plurality of isolating switches are burnt out, so that an overhead line is forced to be powered off, certain electric quantity loss is caused, and economic loss is caused to power supply enterprises.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the not good shortcoming of three-phase isolator closed condition, provide a take spherical contact's isolator.
The utility model adopts the following technical scheme:
the utility model provides a take isolator of spherical contact which the key lies in: the disconnecting link comprises a supporting seat and a disconnecting link arranged on the supporting seat, the disconnecting link is composed of a spherical contact and an isolation blade, and a movable end of the isolation blade is provided with a hollow structure and is in movable contact with the spherical contact through the hollow structure.
By adopting the scheme, the special combination of the hollow structure and the spherical contact is utilized, when the isolation switch is closed, if the isolation switch has slight deviation, the spherical contact can guide the isolation blade to return to the correct direction, a certain correction function is realized, and the success rate of the isolation blade closing is increased.
Preferably, keep apart the blade and be equipped with two, two keep apart the stiff end of blade and connect as an organic wholely, two keep apart the expansion end of blade and all be equipped with the arc, two keep apart parallel and the relative setting of arc of blade, form with the hollow structure that spherical contact agrees with mutually.
By adopting the scheme, the two isolating blades are adopted to form the hollow structure, so that the hollow structure has certain elasticity, and the radius of the hollow structure can be properly adjusted.
Preferably, the radius of the arc on the isolating blade is consistent with the radius of the spherical contact.
By adopting the scheme, the arc radius is consistent with the radius of the spherical contact, so that the isolation blade can be better contacted with the spherical contact, and reliable closing can be achieved.
Preferably, the two sheets are fixed by fixing screws, an insulating operating rod is installed on the isolation blade through the fixing screws, and an operating main shaft is arranged at the bottom of the insulating operating rod.
By adopting the scheme, when the isolation blade needs to be closed, a worker drives the insulation operating rod to pull down by rotating the operating main shaft, so that the isolation blade is closed downwards.
Preferably, a supporting insulator is arranged at the bottom of the supporting seat.
By adopting the scheme, the supporting insulator is used for supporting the isolation blade and the spherical contact.
Has the advantages that: the utility model discloses simple structure can guarantee that isolator's three-phase isolation blade can reliably be closed simultaneously, reduces equipment damage, improves the power supply possibility.
Drawings
FIG. 1 is a schematic view of the assembly of the isolating blade and the ball contact of the present invention;
FIG. 2 is a top view of a three-phase isolating switch;
the device comprises a spherical contact 1, an isolation blade 2, a supporting insulator 3, an insulating operating rod 4, an operating main shaft 5, a supporting seat 6 and a fixing screw 7.
Detailed Description
The invention is explained in more detail below with reference to exemplary embodiments and the accompanying drawings:
example (b):
as shown in fig. 1, the key of the isolating switch with the spherical contact is as follows: the device comprises a supporting seat 6 and a disconnecting link arranged on the supporting seat 6, wherein a supporting insulator 3 is arranged at the bottom of the supporting seat 6. The disconnecting link is composed of a spherical contact 1 and an isolation blade 2, and a hollow structure is arranged at the movable end of the isolation blade 2 and is in movable contact with the spherical contact 1 through the hollow structure.
Keep apart blade 2 and be equipped with two, two keep apart the stiff end of blade 2 and connect as an organic wholely, two keep apart the expansion end of blade 2 and all be equipped with the arc, keep apart the arc radius on the blade 2 with spherical contact 1's radius is unanimous. The two isolation blades 2 are arranged in parallel and in opposite arc shapes to form a hollow structure matched with the spherical contact 1.
The two blades are fixed by a fixing screw 7, an insulating operating rod 4 is installed on the isolation blade 2 through the fixing screw 7, and an operating main shaft 5 is arranged at the bottom of the insulating operating rod 4.
In this embodiment, the supporting seat 6 is composed of two sides, the supporting seats 6 on the two sides are isolated from each other, one side of the supporting seat is used for supporting and installing the ball-shaped contact 1, and the other side of the supporting seat is used for supporting and installing the fixed end of the isolation blade 2.
As shown in fig. 2, the three-phase isolating switch is composed of three isolating switches of the present invention, which includes three isolating blades 2, three spherical contacts 1, and three insulating operation rods 4. Wherein three isolation blade 2 is installed side by side on one side supporting seat 6, and three spherical contact 1 is installed side by side on opposite side supporting seat 6, and isolation blade 2 and spherical contact 1's mounted position one-to-one. The three insulating operating rods 4 are all installed on the operating main shaft 5, and when the operating main shaft 5 rotates, the three insulating operating rods 4 are driven to be pulled down simultaneously, so that the three isolating blades 2 move downwards until the three isolating blades are contacted and closed with the spherical contact 1.
Finally, it should be noted that the above description is only a preferred embodiment of the present invention, and those skilled in the art can make various similar representations without departing from the spirit and the scope of the present invention.
