Abstract
The utility model is a combined power supply electric surge protector, comprising a protection module and a base seat. The protection circuit comprises a series circuit that a piezo varistor is connected in series with a thermal fuse. Two ends of the series connection circuit are connected in parallel with a graphite multiplayer body formed by a plurality of gap. The first layer of the graphite layer serves as an end grounding of the graphite multiplayer body, the last graphite gap serves as the input end of another end grounding electric surge protector of the graphite multiplayer body, other layers of the graphite gap are individually grounded through a capacitor. Appling the combined protection way of the graphite and the piezo varistor, the electric surge protector actively coordinates the lightning current discharging capacity between the graphite multiplayer and the piezo varistor. The piezo varistor is started for protection under low electrical level, when the protection electrical level rises up and lightning current discharging energy is large, the graphite multiplayer is started for protection. The utility model is characterized by fast response speed, low protection electrical level and big discharging capacity.

The utility model content
The purpose of this utility model is to solving the problem that prior art exists, and provides that a kind of response speed is fast, the protection combined power surge protector that level is low, leakage current is big, simple in structure, easy to use.
The utility model is achieved in that a kind of combined power surge protector; be to constitute by protection module and base; protection module is plugged on the base; be provided with protective circuit and corresponding protection mechanism in the protection module; protective circuit comprises the series circuit that a piezo-resistance and hot fuse are connected in series mutually; one end ground connection of this series circuit; the input of another termination surge protector; the two ends of described this series circuit graphite polylayer forest that constitutes by the multilayer gap in parallel; ground floor graphite gap is as an end ground connection of graphite polylayer forest; end layer graphite gap connects the input of surge protector as the other end of graphite polylayer forest, and the graphite gap of other layer is separately by a capacity earth.
Described graphite polylayer forest can be clipped between two electrode mounting panels, and the bottom of two electrode mounting panels is extended two electrode slices respectively.
The described some electric capacity that are connected with the graphite gap can be arranged on the wiring board, and this wiring board is arranged between two electrode mounting panels and is positioned at the top of graphite polylayer forest.
Described protection mechanism and piezo-resistance and hot fuse can be arranged on the installing rack, and the two side ends of this installing rack bottom is extended with electrode slice respectively.
Described protection structure can be a thermal tripping mechanism; form by heat dropout safety plate, dropout sliding part, spring, remote signalling top rod; hot dropout safety plate is connected with the dropout slide with piezo-resistance respectively; the dropout slide pushes up excellent crimping with spring, remote signalling respectively, the bottom of remote signalling top rod and the remote signalling deflating cap crimping on the base.
Described installing rack can be open design, and the graphite polylayer forest is arranged on the base plate of described installing rack, and the electrode slice of installing rack two side ends bottom flushes with two electrode slice bottoms of side with described electrode mounting panel respectively and on a side vertical plane.
Can offer on the described base and the corresponding electrode slot of described electrode slice, described electrode slot branch both sides are offered, and the motor slot of every side is side by side three.
The electrode slice at described graphite polylayer forest two ends can be in parallel by the electrode slice of the corresponding electrode slot that is provided with on the base with the installing rack two ends that piezo-resistance and thermal tripping mechanism are installed, and common port in parallel is arranged on the base.
Described graphite polylayer forest can be 3,4,5,6,7,8,9 or 10 layers.
The specification of described piezo-resistance can be 34 * 34mm, 20 * 20mm, 32mm or 20mm.
The utility model is because the protection form that adopts graphite and piezo-resistance to combine makes surge protector can carry out the cooperation of organic initiative to the lightning current capacity of releasing between graphite polylayer forest and piezo-resistance.Low at the protection level, when the lightning current capacity of releasing hang down, starts piezo-resistance and protect, when the protection level increases, lightning current is released energy when big, and startup graphite polylayer forest is protected.This surge protector had both been inherited the characteristics of the fast and low protection level of response speed of piezoresistive surge protector, had the big through-flow protective capability of graphite mould surge protector again.In actual use if when using independent graphite mould surge protector and independent piezoresistive surge protector; cooperate when distance need increase the energy that the decoupling inductance coordinates between two protectors during not enough 10m between two types the protector, will be limited protection circuit current loading amount by the load capacity of inductance when using the decoupling inductance.Combined power surge protector of the present utility model then need not decoupler, has both solved the not enough problem of distance, also can qualification not arranged to the protection circuit load current.
