Definitions
- the present invention relates to a structure insulation for medium, high and very high voltage cables carrying direct or alternating current.
- These cables generally consist of a core conductor surrounded by an isolation structure attached to it coaxial.
- This structure includes at least a first semiconductor layer placed in contact with the cable core, itself surrounded by a second layer electrically insulating, in turn covered by a third layer semiconductor.
- Other outer layers are used to cable protection.
- the insulating layer is usually based on high density or low density polyethylene, polyethylene crosslinked, or alternatively of ethylenepropylene-diene terpolymer with main methylene chain (EPDM).
- EPDM ethylenepropylene-diene terpolymer with main methylene chain
- Semiconductor layers are generally composed of a polar matrix, most often a copolymer of ethylene and alkyl acrylate, which is charged with carbon black.
- the amount of charge varies according to the nature of the carbon black used.
- the proportion of filler is generally between 28% and 40%.
- the dielectric strength of such a cable is very linked the quality of the interface between the semiconductor layer and the insulating layer.
- the slightest roughness in this interface can cause a reinforcement of the field electric and lead to breakdown and perforation of the insulating layer.
- the matrix of semiconductor layers currently sold high voltage cables is generally based on a polymer of melt index or high "melt index" of around 17 (A high "melt index” is the sign of the presence of low molar masses, it is measured according to ASTM standards reference D1238 or NFT 51-016), and having a very large mass distribution molars. But we found in the insulating layer, proximity of the semiconductor layers, the appearance of loads of space, the accumulation of which deterioration of the dielectric strength of the insulation go to the breakdown.
- Some semiconductor manufacturers use apolar matrices based on an ethylene copolymer (EPR: thermoplastic ethylene-propylene elastomer, or EPDM: ethylene-propylene-diene chain terpolymer main methylene), to which they add oils or plasticizers to facilitate obtaining a good state of surface of the semiconductor layer. Now these oils or plasticizers diffuse in the insulating layer and create level of the interface between the semiconductor layer and the insulating layer, where the electric field is the highest, a region of lower dielectric strength.
- EPR thermoplastic ethylene-propylene elastomer
- EPDM ethylene-propylene-diene chain terpolymer main methylene
- the object of the present invention is to provide a insulation structure for medium, high, and very high voltage carrying direct or alternating current, having more stable dielectric characteristics over time than those known so far.
- the object of the present invention is a structure insulation for cable comprising at least a first semiconductor layer contiguous and coaxial with the core of the cable, surrounded by a second layer electrically insulating, itself covered by a third layer semiconductor.
- the semiconductor layers are composed exclusively of a matrix comprising only apolar polymers with a molar mass greater than 1000, and of a conductive charge.
- the components of the matrix have a molecular mass greater than 5000.
- the semiconductor layers contain compounds with low molecular weights or additives, such as oils or plasticizers, these compounds migrate into the insulating layer. This phenomenon results in the formation of space charges which will cause electric field enhancement and can lead subsequent to breakdowns.
- This field reinforcement is linked to the quantity of charges formed but also to their mobility: a quantity of uniformly distributed loads does not giving no field reinforcement as important as the same amount of localized charges. This migration can be produce during implementation or during cable operation.
- composition according to the invention comprising only mass compounds high molar, prevents migration of species into the insulating layer and thereby the accumulation of charges of space near the interfaces.
- the polymers are chosen from polyethylene, polypropylene, polystyrene, and their copolymers, alloys of polymers chosen from polyethylene, polypropylene, polystyrene, and their copolymers, and mixtures of the compounds chosen from polyethylene, polypropylene, polystyrene, their copolymers, and previously cited alloys.
- the polymers are chosen from elastomers polyolefinic thermoplastics and their mixtures.
- the present invention has the advantage of stabilizing the dielectric characteristics of the structure isolation by suppressing the migration of the compounds of low molar mass. As a result, the quality of the interface between the different layers becomes a less critical parameter.
- the filler is a carbon black containing the least possible impurities. You can use a baked black or a black "KETJEN", but we will preferably choose a black acetylene which is much purer.
- the matrix also contains before its shaping a crosslinking agent. After shaping material by extrusion, it can be cross-linked for to improve its thermomechanical properties. These properties are particularly critical for cables carrying alternating current.
- the pressure wave test is carried out using the installation shown in Figure 1. This test allows to assess the strengthening of the electric field in a isolation structure.
- the installation shown in Figure 1 consists a laser 10 "YAg” whose beam is sent on a target 11 corresponding to sample 1 of which each semiconductor constitutes an electrode (+) and (-).
- This beam absorbed at the surface of electrode 2 (-) breaks down this surface by pyrolysis, and the gases emitted cause a wave of pressure passing through the sample. This wave modulates the charge-images on the electrodes and gives access to the volume charge density in the sample.
- a photodiode 12 makes it possible to synchronize a detector 13 with laser 10.
- the circuit is supplied electrically by a high voltage power supply 14 provided resistance 15.
- the data recorded are transferred to be processed by a computer 16 and represented as a function of time on a recorder graph 17.
- the laser 10 sends a wave on the target 11 causing the appearance of space charges and the modification of the distribution of the electric field which then is measured by detector 13.
- Example 4 A sample similar to that described in Example 4 is prepared but by adding to the matrix semiconductor layers, a paraffinic oil with reason 5% by weight relative to the matrix.
