Abstract
The utility model discloses a leakage protector. The leakage protector comprises a shell, wherein a ring-shaped iron core is arranged in the shell; a center hole is formed in the center of the ring-shaped iron core; a primary winding is penetrated in the center hole of the ring-shaped iron core; a secondary coil winding is wound on the outer surface of the ring-shaped iron core; the primary winding consists of a bus which penetrates through the center hole of the ring-shaped iron core, and a circuit board which is connected with the bus; a connection terminal, a resistor and a power module, which are connected in series, are arranged on the circuit board. The primary winding consists of the bus which penetrates through the center hole of the ring-shaped iron core, and the circuit board which is connected with the bus, so that the size of the ring-shaped iron core can be greatly reduced, then the leakage protector is simpler in structure and smaller in appearance volume size, and the production cost is effectively reduced; besides, an insulating protective layer is coated on the outer surface of the secondary coil winding, so that the safety performance of the leakage protector can be further improved so as to prevent accidents and ensure the personal safety of operators.
Description
Technical field
The utility model relates to a kind of earth leakage protective device.
Background technology
Earth leakage protective device mainly is used for when equipment generation leak current fault and to the person electric shock that fatal risk is arranged, protecting; Present existing earth leakage protective device is mainly earth leakage circuit breaker; Its structure is complicated usually, and the overall volume size is bigger, and production cost is higher.
Summary of the invention
To the deficiency of prior art, the utility model provide a kind of simple in structure, the overall volume size is less, production cost is lower and the better earth leakage protective device of security performance.
For realizing above-mentioned purpose; The utility model provides a kind of earth leakage protective device, comprises shell body, is provided with annular core in the described shell body; The center of annular core is provided with centre bore; Be equipped with winding in the centre bore of annular core one time, be arranged with the secondary coil winding on the outer surface of said annular core, a described winding is made up of bus that passes the annular core centre bore and the wiring board that is connected with bus; Described wiring board is provided with splicing ear, resistance, the power model of mutual series connection, and described secondary coil winding outer surface is coated with insulating protective layer.
The beneficial effect of the utility model is: adopt said structure; Because a described winding is made up of bus that passes the annular core centre bore and the wiring board that is connected with bus; Therefore can reduce the size of annular core widely; Thereby obtain the earth leakage protective device that structure is more simple, the overall volume size is littler, reduce production costs effectively; Because described secondary coil winding outer surface is coated with insulating protective layer, therefore can further improve the security performance of earth leakage protective device in addition, prevent accident, ensure operator's personal safety.
It is epoxy resin layer that the utility model can further be set to described insulating protective layer.
It is the unsaturated-resin layer that the utility model can further be set to described insulating protective layer.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
As shown in Figure 1ly provided a kind of earth leakage protective device; Comprise shell body 1, be provided with annular core 2 in the described shell body 1, the center of annular core 2 is provided with centre bore 21; Be equipped with one time winding in the centre bore 21 of annular core 2; A described winding is made up of bus that passes annular core centre bore 21 3 and the wiring board 4 that is connected with bus 3, and described wiring board 4 is provided with splicing ear 5, resistance 6, the power model 7 of mutual series connection, is arranged with secondary coil winding 8 on the outer surface of said annular core 2; Described secondary coil winding 8 outer surfaces are coated with insulating protective layer, described insulating protective layer preferred epoxy layer or unsaturated-resin layer.
Adopt said structure; Because a described winding is made up of bus that passes annular core centre bore 21 3 and the wiring board 4 that is connected with bus 3; Therefore can reduce the size of annular core 2 widely; Thereby obtain the earth leakage protective device that structure is more simple, the overall volume size is littler, reduce production costs effectively; Because described secondary coil winding 8 outer surfaces are coated with insulating protective layer, therefore can further improve the security performance of earth leakage protective device in addition, prevent accident, ensure operator's personal safety.
