The outside of described upper cover is provided with the binding post electrically connected with fuse, wherein: the inner side of described upper cover is provided with temperature detect switch (TDS),
Described temperature detect switch (TDS), fuse, binding post are connected.
By using technique scheme, utilizing the temperature of temperature detect switch (TDS) monitoring enclosure interior, once shell body temperature surpasses
Crossing the preset value of temperature detect switch (TDS), temperature detect switch (TDS) i.e. disconnects the electrical connection between fuse and binding post, until shell body temperature fall
To safe temperature, temperature detect switch (TDS) connects the electrical connection of fuse and binding post again, play with shell body temperature height change and
The effect making the electrical connection circulation of capacitor cut-off, both ensure that the safe handling of housing, fuse can be prevented again because of the most overheated
And the permanent electrical connection exiting capacitor.
This utility model is further arranged to: the inner side of described housing is fixedly installed junction block, described temperature detect switch (TDS) with
Junction block grafting.
By use technique scheme, utilize the mode of grafting that temperature detect switch (TDS) is installed, its dismounting, easier for installation.
This utility model is set to regard to a new step: described dielectric is epoxy resin.
By using technique scheme, the deformation retract rate of epoxy resin is little, product size good stability, and hardness is high,
Pliability is preferable.
This utility model is further arranged to: described temperature detect switch (TDS) is fixing to be embedded in described epoxy resin, and described temperature
The grafting direction of control switch is vertical with the opening direction of housing.
By using technique scheme, in this programme, it is connected fixing to temperature detect switch (TDS) and epoxy resin, though temperature control
When the breaking function of switch lost efficacy, shell body temperature raises, and produces dilatancy, and this Zona transformans moves temperature detect switch (TDS) and moves so that temperature
Control switch departs from junction block, thus disconnects the power supply of capacitor, prevents capacitor from exploding.
This utility model is further arranged to: described temperature detect switch (TDS) along housing radially outward from convex edge.
By using technique scheme, utilize convex edge to increase and lose at housing expanded by heating and temperature detect switch (TDS) break function
In the case of effect, temperature detect switch (TDS) and the contact area of epoxy resin, it is ensured that temperature detect switch (TDS) can separate with junction block in time.
This utility model is further arranged to: described temperature detect switch (TDS) has an aluminium shell, and described convex edge and aluminium shell
It is wholely set.
By using technique scheme, the convex edge of aluminum also add the contact area of epoxy resin and temperature detect switch (TDS),
The temperature monitoring of another temperature detect switch (TDS) is more accurately, in time.
Compared with prior art, this utility model has the advantage that
1, built-in temperature detect switch (TDS), the overheated of recycling-guard low-voltage shnt capacitor is crossed stream, is significantly improved making of capacitor
Use the life-span；
2, advanced production equipment, excellent import raw material, adds the production technology of uniqueness, has fully ensured product
High-quality；
3, unique design, has ensured that product can adapt to higher ambient temperature and system voltage, bigger field of fluctuating
Institute.

Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described further.
Embodiment 1: seeing Figure of description 1 and 2, a kind of cylindrical low-voltage shnt capacitor, including in cylinder
Tubular shell 1, having an opening above of housing 1, fuse 2 concentric having composite polypropylene film rolling to be coiled into is placed on housing 1
In, filling epoxy resin in housing 1 thus fuse 2 is encapsulated in the middle part of housing 1.Upper cover 3 sealing cover housing 1 upper opening from
And close whole capacitor.
An installation bolt assembly 4 is fixedly mounted, for fixed capacity device in the lower section of housing 1.Binding post 6 is fixed
Above upper cover 3, and binding post 6 is electrically connected by wire 5 with fuse 2.A junction block 8 is fixed in the lower section of upper cover 3, should
Wire 5 is disconnected by junction block 8, double-metal sheet type temperature detect switch (TDS) 7 and junction block 8 grafting.By temperature detect switch (TDS) 7 again communication conductive wire 5.
The principle of this programme is: set a safe temperature, when the temperature of cylindrical capacitor first to temperature detect switch (TDS) 7
When raising because of surge and exceed this temperature, temperature detect switch (TDS) 7 disconnects fuse 2 and binding post 6 because bimetal leaf produces bending
Between electrical connection, until capacitor because of current interruptions, at a temperature of be down to safe temperature range after, bimetal leaf reply original shape make
Fuse 2 re-forms with binding post 6 and electrically connects, and fuse 2 obtains power supply and works on, and this is above-mentioned described circulating guarantor
Protect, utilize the effective protective condenser of the method, it is to avoid the fuse 2 in capacitor is because of the most overheated i.e. the most permanent disconnection capacitor system
Electrical connection in system.
Embodiment 2, the present embodiment differs only in embodiment 1: see Fig. 3, and temperature detect switch (TDS) 7 is inserted with junction block 8
Connecing direction vertical with the opening of housing 1, and the side of temperature detect switch (TDS) 7 has the convex edge 9 of projection, this convex edge 9 is along the radial direction of housing 1
Extend.
Safety, the explosion-proof of capacitor are made lifting by said structure by the present embodiment further.At temperature detect switch (TDS) 7
Thermal cutoff disabler in the case of, epoxy resin in housing 1 can expanded by heating and then extruding housing 1 until housing 1 explodes
Split.And in the present embodiment, this situation once occurring, epoxy resin i.e. extrudes temperature detect switch (TDS) 7 expanding when, passes through convex edge
The setting of 9 is effectively increased the epoxy resin active force to temperature detect switch (TDS) 7, and before housing 1 bursts, epoxy resin will be opened in temperature control
Close 7 to pull open from junction block 8, thus disconnect the electrical connection between fuse 2 and binding post 6, stop powering to fuse 2 thus hinder
Disconnected thermal source, effectively prevents capacitor from exploding.
The foregoing is only preferred embodiment of the present utility model, be not limited to this utility model, all in this practicality
Within novel design concept, any modification, equivalent substitution and improvement etc. made, should be included in protection of the present utility model
Within the scope of.
