Description
Technical Field
The invention relates to an electric facility, in particular to an easily replaceable GW16/17 type isolating switch movable contact piece.
Background
The GW16/17 type isolating switch is a commonly used isolating switch in a power system, during the switching-on and switching-off process of a disconnecting link, a static contact rod and a movable contact piece generate arc discharge in the contact process, the contact part of the static contact rod and the movable contact piece is often found to have obvious ablation signs, the electrical conductivity of the whole isolating switch is obviously influenced after the ablation of the part,
during maintenance, the static contact rod can be rotated to change the relative position of the contact with the movable contact piece, so that ablation contact is avoided, and the movable contact piece is connected with the internal lifting rod, so that the whole upper conductive arm needs to be disassembled to be replaced.
The current methods have the following disadvantages and drawbacks:
1. the GW16/17 type isolating switch used at present has a silver plated layer on the whole moving contact, but the contact has only one point, if the contact is burnt, the whole moving contact needs to be replaced, and the moving contact cannot be used at other positions.
2. The movable contact piece is replaced by disassembling the whole upper conductive arm, a large amount of time is consumed, the upper conductive arm is disassembled and reinstalled, more parts are involved, higher technical difficulty is caused, and installation errors can lead to unreliable operation of the disconnecting link
In view of the defects of the prior art, the invention aims to provide an easily replaceable GW16/17 type disconnecting switch movable contact spring, which can be replaced by a simple means without disassembling the upper conductive arm of the disconnecting switch, and has reasonable structural design, high efficiency and convenience.
Disclosure of Invention
The invention provides an easy-to-replace GW16/17 type isolating switch movable contact spring, which can quickly adjust the position of the movable contact spring or replace the movable contact spring when the movable contact spring is ablated.
The invention adopts the following technical scheme.
The GW16/17 type isolating switch movable contact piece is easy to replace, and the switch movable contact piece (6) comprises a movable contact piece base (1), a conductive piece (2) and a conductive strip (3); a plurality of bolt holes are formed in the movable contact spring base; the conducting strip is detachably fixed at the bolt hole (7) of the movable contact spring base by a fastener; the fixing position of the conducting strip on the moving contact strip base can be adjusted by changing the base bolt hole connected with the conducting strip.
The top and the bottom of the movable contact spring base are respectively provided with a bolt hole connected with the arc striking contact finger (4) and the lifting rod (5).
The movable contact spring base and the conducting strip are both U-shaped in cross section, and the U-shaped conducting strip is sleeved on the U-shaped movable contact spring base.
And two side surfaces of the middle part of the movable contact spring base are respectively provided with three base bolt holes to form a fixed position of the conducting plate.
The conductive band is a flexible conductive band; the top of the conductive belt is provided with a bolt hole.
The movable contact piece forms an electric contact surface by a silver-plated layer on the surface; when the burning position of single burning appears on the electric contact surface, the electric contact is prevented from being carried out at the burning position by adjusting the fixing position of the conducting strip on the base of the movable contact piece.
When the burning positions of a plurality of burning positions appear on the electric contact surface, the electric contact is prevented from being carried out on the burning positions by replacing the conducting strips.
Compared with the prior art, the invention has the following beneficial effects: when isolator overhauls, need not to disintegrate and dismantle the electrically conductive arm, only need change the relative position of removable formula conducting strip and movable contact spring base for the first time, can solve because of the contact surface ablates the problem that leads to switch electric conductive property to descend, ablates the back once more, only need dismantle change removable formula conducting strip part can, it is high-efficient convenient, can effectively practice thrift the maintenance cost, have wide application prospect.

Detailed Description
As shown in fig. 1-5, an easy-to-replace GW16/17 type isolating switch moving contact, the switch moving contact 6 includes a moving contact base 1, a conducting strip 2, a conducting strip 3; a plurality of bolt holes are formed in the movable contact spring base; the conducting strip is detachably fixed at the movable contact spring base bolt hole 7 by a fastener; the fixing position of the conducting strip on the moving contact strip base can be adjusted by changing the base bolt hole connected with the conducting strip.
The top and the bottom of the movable contact spring base are respectively provided with a bolt hole connected with the arc striking contact finger 4 and the lifting rod 5.
The movable contact spring base and the conducting strip are both U-shaped in cross section, and the U-shaped conducting strip is sleeved on the U-shaped movable contact spring base.
And two side surfaces of the middle part of the movable contact spring base are respectively provided with three base bolt holes to form a fixed position of the conducting plate.
