Abstract
The invention provides a circuit breaker molded case which is simple, reliable, capable of saving space and capable of being replaced. The circuit breaker molded case comprises a molded case body and pluggable baffles. The molded case body uses a plastic insulator as a device outer shell and is used for isolating conductors from metal parts. The number of the pluggable baffles is two, the two pluggable baffles are placed at the center of the outer shell, the pluggable baffles can be dismounted according to conditions and can be replaced by mutual inductors, hence an electronic type molded case circuit breaker can be achieved through conversion, and by the adoption of the molded case body, the conductors and the metal parts can be isolated. The circuit breaker molded case has the advantages that the two-stage protection functions of overload delay and short-circuit instantaneousness are achieved, and the isolation function and the safety protection function can further be achieved; each pluggable baffle can be dismounted according to the conditions and be replaced by the mutual inductor, and the electronic type molded case circuit breaker is achieved through conversion. The electronic type electric leakage device has the advantages of being small in size, high in precision and high in sensitivity.
Description
Technical field
The invention belongs to circuit-breaker technical field, be specifically related to a kind of circuit breaker and mould shell.
Background technology
Along with the development of human sciences's technology; circuit breaker refers to the electric current that can close, carry and cut-off under normal loop condition, and can close, the switching device of carrying and the electric current under cut-offfing abnormal loop condition (comprising short circuit condition) in official hour.Circuit breaker can be used to distribute electric energy; infrequently start asynchronous motor; protection is carried out to power circuit and motor etc., can automatic shutdown circuit when serious overload or short circuit and the fault such as under-voltage occur for they, its function is equivalent to Fuse switch and the combination of crossing underheat relay etc.And generally do not need to change parts after disjunction fault current.Low-voltage circuit breaker is the important component part of electrical equipment industry, it is complete sets of basic equipment part in machinery industry, low-voltage complete switch equipment is formed primarily of various low-voltage circuit breaker element in a power distribution system, and the function of low-voltage circuit breaker and performance play vital effect to low-voltage complete switch equipment.Generating equipment send electric energy more than 80% by low-voltage circuit breaker distribute use.The requirement of electric system to circuit breaker also improves constantly.Existing distribution system requires that circuit breaker is except can control and simple short circuit, also want to provide to isolate and safety protection function except overload protection by electric current of make-and-break realizing circuit; particularly both provide in the reliability for the person, device security and distribution system new requirement low-voltage circuit breaker be electrical equipment work this, product development and design is all emphasis consideration personal safety, electric wiring and equipment protection, reliably supplies of electric power also.
Summary of the invention
The circuit breaker that technical problem solved by the invention is to provide and a kind ofly saves space, be convenient to dismantle, insulating properties is strong moulds shell.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of circuit breaker moulds shell, comprises and moulds shell housing, pluggable baffle plate.Described shell housing of moulding uses plastic insulation as the shell of device, is used between insulated conductor and metallic member.Described pluggable baffle plate, can replace, and installs instrument transformer, repacks electronic type molded case circuit breaker into, becomes a kind of and multi-functionally moulds shell.
Further, pluggable baffle plate is connected with housing groove, can plug dismounting catch at any time, replace to instrument transformer.
Further, moulding shell housing is that its insulating properties of plastic insulation is strong.
Beneficial effect of the present invention: mould shell housing by employing owing to have employed technique scheme, between insulated conductor and metallic member, has overload time delay, transcient short circuit time two segment protect function, can also provide isolation and safety protection function; By pluggable baffle plate, according to circumstances can dismantle, replace with instrument transformer, convert electronic type molded case circuit breaker to.Breaker of plastic casing is all contained in a plastic casing by contact, arc control device, release and operating mechanism etc.; generally do not consider maintenance; be applicable to the protection switch making branch road; overcurrent trip has Thermomagnetic type and electronic type two kinds; general Thermomagnetic type breaker of plastic casing is non-selective circuit breaker; only have overload long delay and the instantaneous two kinds of protected modes of short circuit, electronic type molded case circuit breaker has the instantaneous and earth fault four kinds of defencive functions of overload long delay, short circuit short time-delay, short circuit.The product that portions of electronics formula breaker of plastic casing is newly released is also with regioselectivity chain function.Most of breaker of plastic casing is manual operation, also has part band electric motor operating mechanism.
Accompanying drawing explanation
Fig. 1 is that circuit breaker moulds shell schematic diagram.Wherein mould shell housing 1; Pluggable baffle plate 2.
Embodiment
As shown in Figure 1: a kind of circuit breaker moulds shell housing, comprise and mould shell housing 1, pluggable baffle plate 2: described in mould shell housing 1 and be used as crust of the device with plastic insulation, be used between insulated conductor and metallic member.Wherein mould on shell housing and have two grooves, be used for placing catch.Described pluggable baffle plate 2, has two panels baffle plate, can dismantle as required, install.Baffle plate also can be replaced with instrument transformer, convert electronic type molded case circuit breaker to, enhance the function of breaker of plastic casing: mould shell housing owing to have employed technique scheme by employing, between insulated conductor and metallic member, there is overload time delay, transcient short circuit time two segment protect function, isolation and safety protection function can also be provided; By pluggable baffle plate, according to circumstances can dismantle, replace with instrument transformer, convert electronic type molded case circuit breaker to.Overload delay protection refers to that limited range that load current exceedes equipment has the danger of burning apparatus, and protective device can be cut off the electricity supply within a certain period of time.Cross the process being loaded with a thermal accumlation, protection act does not need too rapid.For sort time overcurrent, protection should action.
Above an embodiment of invention has been described in detail, but described content is only present pre-ferred embodiments can not be considered to for limiting the scope of the present invention.All equalizations done according to the present patent application scope change and improve, and still all should belong to patent covering scope of the present invention.
