Abstract
The utility model discloses an intelligent circuit breaker. The intelligent circuit breaker includes a circuit breaker (1). The intelligent circuit breaker is characterized in that the circuit breaker (1) is provided with insulating cylinders (3); the insulating cylinders (3) are provided with current transformers (4); and line outgoing terminals (5) of the current transformers (4) are connected with a self-powered microcomputer protection device (2) mounted on the panel of the circuit breaker (1). According to the intelligent circuit breaker of the utility model, the current transformers and the circuit breaker insulating cylinders are pressed and casted on one body; and the self-powered microcomputer protection device is mounted on the panel of the circuit breaker, so no protective power supply is needed. Thus, the 10kV intelligent circuit breaker can replace the function of a conventional high voltage cabinet, and can be in used in places where space is small.
Description
Technical field
The utility model relates to field of circuit breakers, is specially a kind of 10kV intelligent breaker that can play power circuit, electric equipment control and protection.
Background technology
Conventional with 10kV circuit breaker VS1-12, as power circuit, the effect of electric equipment control and protection, need 10kV current transformer, protective device, the protective device power supply of additional collection signal.Large as conventional electric power switchgear house space, the high-voltage board volume that circuit breaker is installed is little to spacial influence greatly, but wants cube very little as the other outdoor ring main unit in street, also has the conditional situation of size.Conventional 10kV circuit breaker VS1-12 and supporting 10kV current transformer, protective device, protective device power supply thereof can not meet dimensional requirement.Conventional 10kV circuit breaker VS1-12 leaves its supporting 10kV current transformer, protective device, protective device source element, has not just had control and protection effect.
Therefore, providing that a kind of to occupy space little, and can coordinate with a kind of 10kV short-circuiting device, play the short-circuiting device device of good power circuit, electric equipment control and protection, has been a good problem to study.
Summary of the invention
In order to overcome above-mentioned deficiency of the prior art, the utility model provides a kind of circuit breaker that can meet reduced size requirement, and makes circuit breaker have intelligence effect, as independent component, power circuit, electric equipment is played to control and protection.
The purpose of this utility model is achieved in that
Intelligent breaker; comprise circuit breaker 1; it is characterized in that: on circuit breaker 1, be provided with insulating cylinder 3, be provided with current transformer 4 on insulating cylinder 3, the outlet terminal 5 of described current transformer 4 is connected with the self-powered microcomputer protecting device 2 being arranged on circuit breaker 1 panel.
Described current transformer 4 die casting are on insulating cylinder 3.
positive beneficial effect:the utility model by by current transformer and Switch Insulation Cylinder die casting in one, self-powered Microcomputer Protection is arranged on circuit breaker panel, without protection power source.10kV intelligent breaker has replaced a function for conventional high-tension cabinet like this, uses the occasion less in space.
Accompanying drawing explanation
Fig. 1 is structural representation one of the present utility model,
Fig. 2 is structural representation two of the present utility model;
In figure, be: circuit breaker 1, self-powered microcomputer protecting device 2, insulating cylinder 3, current transformer 4, outlet terminal 5.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
As shown in Figure 1 and Figure 2; intelligent breaker, comprises circuit breaker 1, is provided with insulating cylinder 3 on circuit breaker 1; on insulating cylinder 3, be provided with current transformer 4, the outlet terminal 5 of described current transformer 4 is connected with the self-powered microcomputer protecting device 2 being arranged on circuit breaker 1 panel.
Described current transformer 4 die casting are on insulating cylinder 3.
The utility model by by current transformer and Switch Insulation Cylinder die casting in one, self-powered Microcomputer Protection is arranged on circuit breaker panel, without protection power source.10kV intelligent breaker has replaced a function for conventional high-tension cabinet like this, uses the occasion less in space.
Above embodiment is only for illustrating preferred implementation of the present utility model; but the utility model is not limited to above-mentioned execution mode; in the ken possessing at described field those of ordinary skill; it any modification of doing within spirit of the present utility model and principle, is equal to and substitutes and improvement etc., within all should be encompassed in the technical scheme scope that the utility model asks for protection.
Claims (2)
1. intelligent breaker; comprise circuit breaker (1); it is characterized in that: on circuit breaker (1), be provided with insulating cylinder (3); on insulating cylinder (3), be provided with current transformer (4), the outlet terminal (5) of described current transformer (4) is connected with the self-powered microcomputer protecting device (2) being arranged on circuit breaker (1) panel.
2. intelligent breaker according to claim 1, is characterized in that: described current transformer (4) die casting is on insulating cylinder (3).
