Technical field
It the utility model is related to a kind of shell mechanism of back-up protection device, more particularly to a kind of back-up protection device of lightning protection device
Shell mechanism.
Background technology
Existing back-up protection device is usually to borrow the electric equipments such as conventional breaker or fuse, is largely up and down
Two panels sheath structure, only a current path.Thunder amplification current and the small afterflow of power frequency etc. all pass through this path.Most cases
It is only to meet thunder amplification current not thread off, and when lightning protection device fails or be short-circuit, conventional back-up protection device can not be coordinated with it
Matching, causes power system on fire or device damage etc..
This product that can not take into account thunder amplification current and the small afterflow of the power frequency simultaneously and single product of function can not meet
The demand of lightning protection industry.If necessary to communication function, or, it is necessary to assembled one piece of supplementary module again during dispaly state, so not only
Tedious process, need more secondary mould or its accessory when making to realize the steps such as assembling, riveted, assembly, and cost compared with
It is high.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of simple in construction, and function is more, not only meets power frequency simultaneously
Thread off in time protection, lightning impulse high current of afterflow is not threaded off, and has state communication function, while lower-cost standby
The shell mechanism of protector.
In order to solve the above-mentioned technical problem, the technical solution of the utility model is to provide a kind of shell knot of back-up protection device
Structure, it is characterised in that：Including base, middle cover and upper lid, middle cover is divided into middle cover downside and middle cover upper side；Middle cover downside with
Base is engaged, and forms power frequency continued flow channel design；Middle cover upper side with it is upper lid be engaged, formed thunder and lightning leakage path structure and
Signal acquisition communication structure；Middle cover upper side and it is upper cover opposite position be provided be used for position thunder and lightning release module, collection mould
The mounting structure of block and communication interface modules.
Preferably, the middle cover is provided with lower installing locating slot, the upper lid is provided with upper installing locating slot, and upper installation is fixed
Position groove matches each other with lower installing locating slot, forms the mounting groove for module of being released for positioning placement thunder and lightning.
Preferably, the middle cover is provided with the connecting lead wire for being used for connecting power frequency continued flow circuit and thunder and lightning leadage circuit terminal
Hole, close a floodgate and the collection drive hole of gate-dividing state information for transmitting protector, connecting lead wire hole, collection drive hole through
Middle cover downside and middle cover upper side.
Preferably, the positioning boss for installing positioning acquisition module is designed with the middle cover and upper lid.
Preferably, the mounting groove for installing communication interface modules is designed with the middle cover and upper lid.
Preferably, the middle cover, the edge of the mounting groove on upper lid are provided with groove.
Preferably, in addition to the groove match, for blocking the mounting groove, when without communication interface modules
When, make the baffle plate flushed in appearance with middle cover, upper outer side of lid face.
Device provided by the utility model overcomes the deficiencies in the prior art, is dexterously provided with the both sides of middle cover different
Shape, number of molds is not only reduced, while decrease the quantity of parts；Structure is relatively easy, is dropped on certain depth
Low making and production cost；Middle cover, on lid set mounting groove when, be provided with dismountable baffle plate again, dexterously realize
Multiple functions are flexibly arranged in pairs or groups；Not only meet that thread off in time protection, lightning impulse high current of power frequency continued flow is not threaded off simultaneously, and tool
Stateful communication function.
