Abstract
The utility model provides an insulating bracket device for the withstand voltage test on parallel cables and mainly applied to the high-voltage test on transformer stations, which comprises at least two insulating brackets. The insulating brackets are connected together by means of connection wires. Each insulating bracket comprises a base, an upright bracket fixed on the base, and a clamping unit arranged at the top of the upright bracket. The upright brackets are high-voltage resistant and insulated and each clamping unit is composed of a fixed arm fixed onto the upright bracket, and a wire clamp arranged at one end of the fixed arm. The connection wires are connected with corresponding insulating brackets by means of the wire clamps. The wire clamps are also connected with test connection wires connected with to-be-tested phase wires. According to the technical scheme of the utility model, a plurality of insulating brackets are connected in series as a whole by means of connection wires, so that a plurality of identical phase wires can be simultaneously tested. That is, through the primary boosting process, a plurality of identical phase wires can be simultaneously tested. Therefore, the detection time is saved and the working efficiency is improved.
Description
Technical field
The utility model relates to a kind of transmission facility and power cable checkout equipment, is specially a kind of cable voltage insulator rack for experiment device of detection streamer resistance to pressure.
Background technology
At present in the operation process such as Electric Power Line Overhaul, station, for cable voltage, testing a normally minute phase line tests separately, if carry out upkeep operation in the transformer station more than 110KV, because number of cable is more, wherein 10KV or 35KV power cable outlet number accounted for the overwhelming majority, by 20 minutes every cable testing time, article 10, cable just takies 200 minutes, add and disconnect test the end of a thread, mobile device equal time, all needs about 4-5 hour conventionally.And take more manually, work efficiency is not high and can extend power off time.
Summary of the invention
For above-mentioned deficiency, designed a kind of cable withstand voltage test insulating support device in parallel, having solved once boosts detects the problem of many circuits simultaneously.
A cable withstand voltage test insulating support device in parallel, comprises insulating support, it is characterized in that having at least two insulating supports to form, and between each insulating support, by wire connecting line, is connected.
Described cable withstand voltage test insulating support device in parallel, it is characterized in that described insulating support comprises base, be fixed on the staking on base and be arranged at the clamp device at staking top, described staking is high pressure resistant insulation support, and described clamp device comprises the fixed arm being fixed on staking and is placed in the wire clamp of fixed arm one end.
Described cable withstand voltage test insulating support device in parallel, is characterized in that described connecting line connects each insulating support by wire clamp, is also connected to and the test connection that detects phase line and be connected on described wire clamp.
Cable of the present utility model withstand voltage test insulating support device in parallel by several insulating supports are integrated by wire series winding, can detect several phase isopens simultaneously, by once boosting, detects several phase isopens simultaneously.Save detection time, improved work efficiency.
Accompanying drawing explanation
Fig. 1 is high pressure Test Field schematic diagram;
Fig. 2 is insulating support structural representation.
In figure, 1-fixed arm, 2-wire clamp, 3-staking, 4-base, 5-test instrument, 6-connecting line, 7-test connection, 8-insulating support.
Embodiment
With reference to accompanying drawing 1, cable of the present utility model withstand voltage test insulating support device in parallel, include branched insulating support 8, between each insulating support, by wire connecting line 6 series windings, connect, each insulating support is connected with the tested phase line of homophase by a test connection 7 respectively, and the end points of connecting line is connected with detection test instrument 5.Shown in figure, five switch cubicles of one-time detection in the present embodiment, adopt five insulating supports 8, the test connection 7 on each insulating support 8 are connected respectively to the A phase of corresponding switch cubicle, and test connection being connected on connecting line 6.Power-on makes test instrument 5 boost to predetermined value, detects the withstand voltage qualified situation of each switch cubicle wiring.When there is exceptional value, then detect respectively the A phase line of each switch cubicle, determine it is which bar circuit goes wrong.And change.So carry out three processes of boosting and can detect all phase lines of five switch cubicles.Saved for 80% detection time.
Shown in Fig. 2, insulating support has a base 4, is fixed with staking 3 on base, on staking top, there is a fixed arm 1, on described fixed arm, be shaped with screw thread, two nuts that are socketed on fixed arm form wire clamp 2, and connecting line 6 is fixed on wire clamp with test connection 7.
Above-mentioned staking and fixed arm, wire clamp all adopt high pressure resistant material to make.
