Description
Technical field
The present invention relates to a kind of current limiter, more particularly to a kind of built-in pillar current limiter.
Background technology
During Power System Shortcuts, because short circuit current flow is very big, equipment temperature rise is raised rapidly, while big electric power is produced,
These can all cause the damage of power equipment.In order to lower the harm that short circuit is brought, short circuit current flow is limited by certain method
System protects power system device under prospective short circuit current.Existing current limiter is generally by fault detection unit, breaker
And current-limiting impedance composition, wherein breaker is in parallel with current-limiting impedance, under power system normal operation, disconnected in current limiter
Road device is in closure state, because breaker has relatively low contact resistance, therefore, and rated current passes through breaker, current limliting resistance
Anti- almost no electric current.When power system is short-circuited, detection unit detects failure, and breaker disconnects, and produces electric arc, electricity
Stream flows into the current-limiting impedance in parallel with breaker, and short circuit current flow is limited in the range of requirement, the short circuit current flow after current limliting by
Another breaker disjunction, so as to cut off failure.And existing current limiter is in use, current limit levels are very low, it is impossible to
Protect the safety of electrical equipment.
Therefore, to solve the above problems, spy provides a kind of new technical scheme.
The content of the invention
The present invention provides a kind of built-in pillar current limiter.
The technical solution adopted by the present invention is:
Vertical lead to is provided with a kind of built-in pillar current limiter, including insulation mandrel, base station, resistor disc and aluminium head, the base station
Hole, the insulation mandrel end passes through the through hole of base station, and the end of the insulation mandrel is provided with outside annular groove, the insulation mandrel
Portion is wound with coil, and described be provided with around through hole can place the groove of resistor disc, and the head end of the insulation mandrel is provided with
Aluminium head.
Further, the trapezoidal structure of the base station.
Further, a segment distance is left between the resistor disc and coil.
Further, it is threadedly coupled between the aluminium head and insulation mandrel.
Further, the quantity 5-10 pieces of the resistor disc.
The beneficial effects of the invention are as follows:It is simple in construction, be easily installed, it is safe and convenient to use, using aluminium head, insulation mandrel and
The mode that resistor disc is engaged, when short circuit current flow occurs in circuit, due to the effect of resistor disc, prevents power frequency continued flow from producing, keeps away
Exempt from insulated conductor to be blown, it is ensured that the security of household electrical appliance, extend the service life of electrical equipment.
