Detailed Description
The noun explains:
a voltage transformer: the Transformer is an instrument for transforming Voltage, similar to the Transformer. However, the purpose of transforming voltage by the transformer is to conveniently transmit electric energy, so that the capacity is very large, and usually kilovolt-ampere or mega volt-ampere is taken as a calculation unit; the voltage transformer is mainly used for supplying power to a measuring instrument and a relay protection device, measuring the voltage, power and electric energy of a line, or protecting valuable equipment, a motor and a transformer in the line when the line fails, so that the capacity of the voltage transformer is small, generally only a few volt-amperes and dozens of volt-amperes, and the maximum voltage of the voltage transformer does not exceed one thousand volt-amperes.
As shown in fig. 1, the utility model discloses a PT connecting cable, including plug 1, cable conductor 2, PT plug 3, earth connection 4, plug 1 be equipped with on the PT plug 3 respectively earth connection 4, cable conductor 2 is installed constitute the PT plug combination on the PT plug 3, plug 1 is installed the PT plug combination on the cable conductor 2, plug 1 with cable conductor 2 is demountable installation.
Plug 1 includes preceding plug, preceding plug is installed on cable conductor 2, PT plug combination one end is passed through the 630A of preceding plug and switch board or 1250A sleeve pipe link to each other, the PT plug combination other end passes through PT plug 3 and links to each other with the PT mutual-inductor.
Plug 1 includes the back plug, the back plug is installed on cable conductor 2, PT plug combination one end is passed through the front plug tail end connection of back plug and switch board, the PT plug combination other end passes through PT plug 3 and links to each other with the PT mutual-inductor.
The power is small in use according to the use condition of the PT transformer, so that the cross section of the cable wire 2 in the PT connection cable is preferably 25mm2Or 35mm2。
The cable 2 comprises a cable with a core preferably copper.
The cable conductor 2 comprises a cable conductor with a wire core being an aluminum core and a copper-aluminum terminal, and the aluminum core cable conductor adopts the copper-aluminum terminal for transition.
The cable 2 is a flexible cable. Because the switch board inner space is limited, and the electric wire netting requires the switch board to develop towards miniaturization direction in addition, therefore PT connecting cable uses cable conductor 2, should be as short as possible, but shorter cable conductor probably can not satisfy the requirement that the cable accessories minimum is peeled off and cut the size, consequently, PT connecting cable should prefer the flexible cable, when making the straight-line distance be not enough to satisfy and peels off and cut the size, can be crooked with the cable, satisfies the user demand.
In order to meet the requirements of different use scenes, the cable 2 can adopt a cable with a copper shielding layer or a cable without the copper shielding layer.
The plug 1 adopts a shielding type plug or a non-shielding type plug.
And selecting an adaptive structure to be matched with the PT transformer according to the structure of the PT transformer. If the PT transformer is in an external conical structure, a PT plug is adopted for matching; if the umbrella skirt structure is adopted, indoor terminal matching is adopted.
The plug 1 can match with plugs with corresponding sizes according to the sizes of the inner sleeves of the power distribution cabinet, such as the front plugs or the rear plugs of 630A and 1250A of EN50151:2010, the front plugs or the rear plugs of 200A and 600A of IEEE Std 386 and 2006, and also can use standard non-standard plugs.
The utility model has the advantages that: adopt the utility model discloses a PT connecting cable is by cable accessories factory design, shell and cut, installation, because the cable accessories who adopts is the design of annex factory, consequently the cooperation of its gold utensil, electric field stress sparse, shell and cut the selection of size, the choice of mounting process, all can accomplish the optimum, not only can greatly improve PT connecting cable's quality, can reduce the switch board producer installation degree of difficulty moreover, promote user experience.
