Abstract
The utility model relates to an integrated one-time and two-time fusion circuit breaker, which comprises a circuit breaker and an FTU (feeder terminal Unit), wherein a box body of the FTU is fixedly arranged on a shell of the circuit breaker, and a control cable of the FTU penetrates out of the box body of the FTU and extends into the shell of the circuit breaker to be connected to an internal circuit of the circuit breaker; the utility model discloses easy to assemble has saved connecting cable's expense.
Description
Technical Field
The utility model relates to a circuit breaker feeder terminal technical field specifically is a circuit breaker is fused to integration one secondary.
Background
In recent years, the national power grid continuously increases investment and construction of the intelligent power grid in order to improve the level of the power distribution network, and in order to solve the problem that a primary high-voltage switch and secondary intelligent feeder terminal equipment are not matched in large-scale construction and transformation of the power distribution network, the national power grid provides a primary and secondary fusion technical scheme of power distribution equipment as early as 2016. The method aims to improve the standardization and integration level of the primary and secondary power distribution equipment, improve the joint debugging test mechanism and requirements of the primary and secondary equipment, and improve the operation level, operation and maintenance quality and efficiency of the power distribution equipment. Because the pole-mounted circuit breaker and the intelligent control unit (FTU) are separately installed, the control cable between the pole-mounted circuit breaker and the intelligent control unit (FTU) is connected by the aviation plug, the connecting cable is longer and exposed, the risk of damage is caused, and meanwhile, the installation operation is also inconvenient.
Disclosure of Invention
The utility model discloses a main objective is in order to solve the problem that above-mentioned current circuit breaker exists, provides an integration one secondary and fuses circuit breaker.
The utility model has the following concrete scheme: the utility model provides a circuit breaker is fused to integration one secondary, includes circuit breaker and FTU, FTU's box fixed mounting is on the casing of circuit breaker, and FTU's control cable wears out FTU's box and stretches into the circuit breaker casing and be connected to the circuit breaker inner circuit.
Sealing box is equipped with to circuit breaker casing outside one end, FTU's box passes through the bolt and is connected with sealing box, control cable passes from sealing box internally, is equipped with waterproof gasket between sealing box and the installation face of circuit breaker casing, is equipped with waterproof gasket between sealing box and FTU's the box installation face.
Cable in the circuit breaker and FTU's control cable between be connected through the circular connector.
FTU's box inner wall is equipped with one deck shielding material, and shielding material is used for shielding the interference of outside electromagnetic field.
Compared with the prior art, the utility model has the following advantages: 1. the FTU is connected with the circuit breaker into a whole, so that the integral installation is more convenient; 2. the length of the connecting cable is greatly shortened, and the cost of the cable is saved.

Detailed Description
Referring to fig. 1-4, the present embodiment is an integrated one-time-two-time fusion breaker, which includes a breaker and an FTU2, wherein a box body of the FTU2 is fixedly installed on the breaker housing 1, and a control cable of the FTU2 passes through the box body of the FTU and extends into the breaker housing 1 to be connected to an internal circuit of the breaker.
In this embodiment, a sealed box 3 is installed at one end of the outer side of the circuit breaker housing 1, the box of the FTU2 is connected with the sealed box 3 through a bolt, the control cable 5 passes through the sealed box 3, a waterproof gasket 8 is installed between the sealed box 3 and the mounting surface of the circuit breaker housing 1, and a waterproof gasket 6 is installed between the sealed box 3 and the mounting surface of the FTU; prevent rainwater from entering the box body from the gap of the mounting surface.
The cable 5 in the circuit breaker of the embodiment is connected with the control cable of the FTU2 through the aviation plug 4; when the circuit breaker producer matches FTUs of different producers, conveniently through aviation plug 4 with the cable and the FTU high-speed joint of circuit breaker.
When a breaker manufacturer provides the FTU, the FTU and the breaker are sold integrally, and an aviation plug is not needed, and the cable can be connected well in the factory.
In this embodiment, the inner wall surface of the FTU2 box is provided with a shielding layer 7, and the shielding layer 7 is used for shielding the interference of an external electromagnetic field.
