Description
Technical field
The utility model relates to a kind of bus connection structure of GIS combined electric appliance equipment, the bus connection structure of free removal when specifically a kind of withstand voltage experiment.
Background technology
Combined electrical apparatus, claim again gas-insulated metal fully-closed switch equipment, it is to be directly connected to together by elements such as circuit breaker, isolating switch, earthed switch, voltage transformer, lightning arresters, and be all enclosed in the metal shell of ground connection, arrange and concentrate, equipment dependability, stability etc. are required high.Therefore, combined electrical apparatus all needs to carry out withstand voltage test after installing, but because the magnitude of voltage tolerating is far above working voltage, therefore GB regulation, does not allow to connect voltage transformer and lightning arrester when withstand voltage.
Technological means is in the past all before withstand voltage experiment, lightning arrester and voltage transformer to be removed, and after withstand voltage test finishes, re-starts installation again.To repeat to install this both increased working strength, and the installation period also having extended, has reduced operating efficiency.
Summary of the invention
The utility model provides a kind of simple in structure, easy to operate in order to overcome above-mentioned defect, without the bus connection structure of removing lightning arrester and voltage transformer and just can carrying out withstand voltage experiment.
The technical solution adopted in the utility model is: a kind of withstand voltage experiment removal-free bus connection structure, comprise housing, disc insulator, fixed contact and conducting rod, it is characterized in that: also comprise moving-conductor and middle contact, described housing is tubing type housing, be connected with disc insulator in the bottom of tubing type housing and the opening part of one of them sidepiece, fixed contact is arranged on the top of the disc insulator of bottom, in housing, contact in the middle of medium position is provided with, middle contact is fixed and is connected with the disc insulator that is arranged on housing sidepiece by supportive conductors seat, middle contact is Mume flower contact, middle part at middle contact is vertically provided with through hole, its profile of described moving-conductor is cylindrical, moving-conductor stretches in the through hole of middle contact, its top is connected by bolt with middle contact, its lower end is stretched out indirect contact and is inserted in fixed contact.
In the utility model, at the upper opening place of housing and that side opening place relative with the disc insulator of housing sidepiece be provided with the cover plate removably connecting.
The utility model has designed the housing of tubing type, contact in the middle of being provided with in housing, middle contact one side is connected with the disc insulator of sidepiece by supportive conductors seat, can be connected with the element such as circuit breaker, isolating switch by this disc insulator, realizes horizontal conductor loop, the utility model is vertically provided with through hole at middle contact middle part, in this through hole, being provided with moving-conductor is connected with the fixed contact of bottom, fixed contact is connected with lightning arrester and voltage transformer by disc insulator and the circuit of lower housing portion, realize vertical conductor circuit, due between moving-conductor and middle contact for detachable connection, therefore, need withstand voltage experiment after equipment assembling time, only moving-conductor need be disassembled from middle contact, middle conductor does not contact with fixed contact, so just, realize without dismounting lightning arrester and voltage transformer and just disconnecting with the withstand voltage loop of combined electrical apparatus, after withstand voltage experiment completes, again moving-conductor is installed in middle contact, in the middle of making, contact is connected with fixed contact, lightning arrester and voltage transformer are just incorporated in combined electrical apparatus again, the utility model is simple in structure, handled easily, save withstand voltage experiment and repeatedly dismantled and installed lightning arrester and voltage transformer, improve operating efficiency.
Brief description of the drawings
Fig. 1 is schematic diagram of the present utility model.
Fig. 2 is the schematic diagram that the utility model is done withstand voltage when experiment.
Embodiment
Now by reference to the accompanying drawings the utility model is further described, Fig. 1 is a kind of embodiment of the present utility model, comprises housing 1, disc insulator 2, fixed contact 3 and conducting rod etc., also comprises moving-conductor 4 and middle contact 5.Described housing 1 is tubing type housing 1, is connected with disc insulator 2 in the bottom of tubing type housing 1 and the opening part of one of them sidepiece, and fixed contact 3 is arranged on the top of the disc insulator 2 of bottom.In housing 1, medium position be provided with in the middle of contact 5, middle contact 5 is Mume flower contact, middle contact 5 is fixed and is connected with the disc insulator 2 that is arranged on housing 1 sidepiece by supportive conductors seat 6, supportive conductors seat 6 is metal link, there is the link of electric conductivity, conventionally be tabular or tubulose or shaft-like, and edge is without wedge angle.Middle part at middle contact 5 is vertically provided with through hole, described moving-conductor 4 its profiles are cylindrical, in the middle of moving-conductor 4 stretches into, in the through hole of contact 5, its top is connected by bolt with middle contact 5, and its lower end is stretched out indirect contact and inserted in fixed contact 3.In the present embodiment, be provided be convenient to the counterbore that connects in middle contact 5 through hole upper ends, be provided with round platform in through hole upper end, so that moving-conductor 4 is connected with middle contact 5, and the bolt connecting do not expose centre contact 5, can prevent electric arc.
In the present embodiment, also at the upper opening place of housing 1 and that side opening place relative with the disc insulator 2 of housing 1 sidepiece be provided with the cover plate 7 removably connecting, for dustproof and protection against the tide or be connected with aerial sleeve.
When the utility model assembling, moving-conductor 4 is arranged in the through hole of middle contact 5, and lower end is connected with fixed contact 3.In the time that needs are done withstand voltage experiment, pull down the bolt on moving-conductor 4 tops, moving-conductor 4 is taken out from middle contact 5, middle contact 5 is not connected with fixed contact 3, sees Fig. 2, and the withstand voltage loop of lightning arrester and voltage transformer and equipment connection just disconnects.After withstand voltage experiment is finished, then moving-conductor 4 is installed in middle contact 5, and its lower end is connected with fixed contact 3, like this, lightning arrester just can normally be connected use with voltage transformer with equipment.
The utility model just can carry out withstand voltage experiment without removing lightning arrester and voltage transformer, have simple in structure, easy to operate, the feature that operating efficiency is high.
