And improve the accuracy of temperature measuring equipment 50.
In the present embodiment, cable connector also includes screen layer, and screen layer is set in outside insulating sleeve 10.Due to by electricity
The electric current of cable can produce magnetic field than larger around electric current, in order to not affect other elements, so screen layer is set in into insulation
Can be above-mentioned magnetic field shielding in cable outside sleeve 10.Meanwhile, the setting of cable connector upper shielding layer can play certain
Ground protection is acted on.If there is breakage in cable core, the electric current for leaking can be reached on ground along screen layer, from
And play a part of safeguard protection.
In the present embodiment, shielding layer grounding hole is set on screen layer.Cable connector is grounded by shielding layer grounding hole,
So as to play a part of safeguard protection.Under running status, screen layer is in zero potential under good ground state, when cable is sent out
After raw failure, it has the ability that short circuit current is conducted in very short time.
In the technical scheme of the present embodiment, cable connector also includes stress cone, and stress cone is arranged in second channel 12,
Stress cone is set on cable.Electric stress control is the particularly important part in medium and high voltage cable attachment design.Electric stress control
System is that the Electric Field Distribution and electric-field intensity inside cable accessory is controlled, that is, takes adequate measures so that electric field
Distribution and electric-field intensity are in optimum state, so as to improve cable accessory reliability of operation and service life.
For cable connector, electric field distortion is the most serious, and affect joint operational reliability maximum is cable external screen
Cover cut-off part, and the impact of cable intermediate joint electric field distortion, except cable external shield cut-off part, also cable end piece insulation is cut
Disconnected place.In order to the electric stress for improving insulation shield layer cut-off part is distributed, specifically, typically changed using following three kinds of modes
It is kind:
1st, geometry method, i.e., alleviate electric field stress and concentrate using stress cone;
2nd, parameters control method, including electric field stress is alleviated using high dielectric constant material and non-linear resistance material this is concentrated
Two kinds of control methods;
3rd, Comprehensive Control method, i.e., alleviate electric field stress and concentrate using capacitance cone.
In the present embodiment, using geometry method, i.e., using stress cone to alleviate cable connector in electric field stress collection
In.In electric angle, stress cone is also most reliable, most efficient method.The cut-off part that stress cone passes through screen layer
Extended, form zero potential horn-like, improved the Electric Field Distribution of screen layer, reduced the possibility of corona generation, subtracted
The destruction of few insulation, so as to improve the service life of cable connector.
In the present embodiment, cable connector also includes equalizing press layer, and equalizing press layer is arranged on first passage 11 and second channel 12
Inwall on, crimp outer circumferential, crimping copper nose 40 and the contact position of insulating sleeve 10 and stress cone and the insulation sleeve of copper nose 40
10 contact positions of cylinder are provided with equalizing press layer.The effect of equalizing press layer is to make conductor and insulating barrier good contact, eliminates conductive surface because not
The smooth internal field's distortion for causing.Specifically, the purpose for equalizing press layer being arranged in cable connector mainly has two:One is uniform
The external electrical field of crimping copper nose 40, and eliminate the air gap between crimping copper nose 40 and insulating sleeve 10.Two are comparable to increase
Radius of corner inside insulating sleeve 10, can improve corner Electric Field Distribution, and playing reduces the purpose of maximum field intensity.Generally
Equalizing press layer is formed by the way of brushing semiconductor varnish (glue).
The application develops a kind of new supporting reception device of temperature measuring type cable connector, specical software system, storage, standby
Part, prompt terminal temperature and position, can arrange temp. indicator by software kit, and can send information according to existing communication technology
To designated mobile phone or background monitoring system, contribute to inspection and failture evacuation of the staff in advance to faulty equipment.
The mentality of designing of the present embodiment middle cable connector is as follows:
Before equipment operation, in cable installation process, the easy heating position of cable is cable crimping copper nose 40 and threaded rod 30
Connecting portion, at this position temperature measuring equipment 50 is installed, and can accurately and effectively measure heating temp, by sensor 70 by signal
It is transmitted into reception device and uploads to receiving terminal, in real time monitoring temperature is carried out to cable connector.
As can be seen from the above description, the utility model the above embodiments realize following technique effect:
Due to the connecting portion that the easy heating position of cable connector is crimping copper nose and threaded rod, therefore install at this position
Temperature measuring equipment can accurately and effectively measure heating temp, then the temperature signal that temperature measuring equipment measurement is obtained is transmitted into into reception dress
Receiving terminal is put and uploads to, it is achieved thereby that carrying out real time temperature monitoring to cable connector.So, staff just can be with
Judge that the heating temp of cable connector, whether in safe temperature range, contributes to staff faulty equipment is examined in advance
Look into and failture evacuation.
The application's has the beneficial effect that:
1st, the real time temperature that staff effectively knows cable connector is contributed to.
2nd, breaker open operation is controlled by design temperature, reduces fault harm.
3rd, it is with strong points, can effectively determine sites of heat generation, point out effect good.
