Abstract
The utility model relates to a current transformer for metering handcarts, which is a kit of high voltage switch cabinets with 10KV, and the utility model is a special device for metering handcarts of handcart type high voltage switch cabinets with 10KV. A primary and a secondary coils of the utility model, and an iron core are sealed and positioned in an epoxy resin casting body; two wiring terminals of the primary coil are matched with a tubular or a rod-shaped socket and a moving plug; the utility model and a voltage transformer can be simultaneously installed on a handcart, and a metering handcart is formed; the metering handcart can use a space structure and a middle position type handcart cabinet which has the same size with a circuit breaker, and the design and the manufacture of the switch cabinet become generalized and standardization.
Description
The utility model relates to a kind of kit of 10KV high-tension switch cabinet, is exclusively used in the metering handcart of 10KV handcart type high-voltage switch cabinet.
The metering handcart of 10KV handcart type high-voltage switch, in use play a part electric energy metrical, its desirable structure is that current transformer, voltage transformer are installed on the metering handcart simultaneously, so that periodically detect and maintenance, also can prevent stealing simultaneously.The breaker chamber space of at present domestic 10KV middle handcart cabinet is less, if metering handcart energy reduced volume, use in the such space of breaker chamber, then can satisfy generalization, standardized production requirement, existing current transformer can not meet this requirement.
The purpose of this utility model is a kind of current transformer that can be applicable to 10KV middle handcart cabinet metering handcart of design, it can be installed in simultaneously with voltage transformer forms the metering handcart on the dolly, the metering handcart can use 10KV middle handcart general size in cabinet breaker chamber and structure space, makes design, manufacturing generalization, the standardization of switch cubicle.
In order to achieve the above object, the utility model is encapsulated in primary winding, secondary coil and the iron core of current transformer in the epoxy resin casting matrix, two terminals of primary winding are fit on tubular socket (copper pipe) and moving plug directly, or connect the bar-shaped contact arm that can assemble moving plug, plug on distance between two moving plugs and the circuit breaker cart is 275mm apart from consistent.
Current transformer is through after transforming like this, can reduced volume, can guarantee certain insulation distance again, can be installed in voltage transformer and form the metering handcart on the dolly, make metering handcart adaptation 10KV middle handcart general size in cabinet breaker chamber and structure indoor, impel design, manufacturing generalization, the standardization of switch.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is that the structure that is used to measure the current transformer of handcart is cutd open figure.
Fig. 2 is that the A of Fig. 1 is to view.
Among Fig. 1, Fig. 2, the primary winding 1 of current transformer and secondary coil 2, iron core 3 all are encapsulated in the epoxy resin casting matrix, two terminals of primary winding directly are assemblied in tubular socket 4 and moving plug 5, or make and to assemble the bar-shaped contact arm that moves plug, distance between two moving plugs is the same with moving plug distance on the circuit breaker cart, is 275 ± 1mm.
Claims (3)
1, a kind of current transformer that is used to measure handcart is characterized in that primary winding, secondary coil and the iron core of current transformer is encapsulated in the epoxy resin casting matrix, the direct fit on tubular socket of two terminals and the moving plug of primary winding.
2, current transformer according to claim 1 is characterized in that two terminals of primary winding can directly connect the bar-shaped contact arm of the moving plug of assembling.
3,, it is characterized in that two distances between the moving plug are 275mm as claim 1,2 described current transformers.
