In order to realize above object, the technical solution adopted in the utility model is:
A kind of electric heater frost protection system; comprise electric heating tube; also include heat-transfer metal plate and Kick type temperature detect switch (TDS); described heat-transfer metal plate is connected with two end in contact of electric heating tube; described Kick type temperature detect switch (TDS) contacts with heat-transfer metal plate and connects; this Kick type temperature detect switch (TDS) is also electrically connected to control electric heating tube switch with electric heating tube simultaneously; the cap seal of Kick type temperature detect switch (TDS) is also provided with the fuse contacted with Kick type temperature detect switch (TDS); described fuse is electrically connected with electric heating tube, can fuse to close electric heating tube when fuse temperature reaches its fusing point.
Further, connect on the live wire of described electric heating tube and zero line and be electrically connected with two relays respectively, control zero line respectively by these two relays and be connected with live wire/disconnect.
The beneficial effects of the utility model are: in electric heater frost protection system of the present utility model, Kick type temperature detect switch (TDS) is arranged on the heat-transfer metal plate that to contact with electric heating tube and connect, the heat that electric heating tube sends is directly delivered on Kick type temperature detect switch (TDS) by heat-transfer metal plate, make Kick type temperature detect switch (TDS) can sense rapidly the variations in temperature of electric heating tube, reach to the operating temperature of Kick type temperature detect switch (TDS) when the temperature of electric heating tube is too high, Kick type temperature detect switch (TDS) just can disconnect rapidly between electric heating tube with power supply and being connected, electric heating tube is made to stop heating, the air-conditioning equipment of protection electric heating tube and this electric heating tube of employing.
In electric heater frost protection system of the present utility model; also be provided with the fuse contacted with Kick type switch at the cap seal of Kick type switch, the heat that electric heating tube sends is passed on fuse by electric heating tube-heat-transfer metal plate-this passage of Kick type temperature detect switch (TDS)-fuse.When Kick type malfunctioning switch; if the constant temperature of electric heating tube raises and reaches to the fusing-off temperature of fuse; fuse just can cut out electric heating tube in the mode of fusing, makes electric heating tube stop heating, protection electric heating tube and the air-conditioning equipment adopting this electric heating tube.
Electric heater frost protection system configuration of the present utility model is simple; highly sensitive, solve the problem that temperature sense in prior art is slow, make electric heater frost protection system more safe and reliable; the fuse simultaneously arranged can make system have the effect of multiple protective, further elevator system fail safe.

Embodiment
Now with specific embodiment, the utility model technical scheme required for protection is described in further detail by reference to the accompanying drawings.
Shown in accompanying drawing 1 to accompanying drawing 3, comprise electric heating tube 1, heat-transfer metal plate 2, Kick type temperature detect switch (TDS) 3 and fuse 4 in the electric heater frost protection system of the present embodiment.Wherein, the two ends of electric heating tube 1 contact with heat-transfer metal plate 2, simultaneously Kick type temperature detect switch (TDS) 3 to be arranged on heat-transfer metal plate 2 and Kick type temperature detect switch (TDS) 3 is directly contacted, define the heat-transfer path of " electric heating tube 1-heat-transfer metal plate 2-Kick type temperature detect switch (TDS) 3 ", the heat that electric heating tube 1 is sent is delivered on Kick type temperature detect switch (TDS) 3 by this path, Kick type temperature detect switch (TDS) 3 is also electrically connected with electric heating tube 1, for controlling electric heating tube 1; The cap seal 31 that fuse 4 is arranged on Kick type temperature detect switch (TDS) 3 directly contacts with cap seal 31, define the heat-transfer path of " electric heating tube 1-heat-transfer metal plate 2-Kick type temperature detect switch (TDS) 3-fuse 4 ", the heat that electric heating tube 1 is sent is delivered on fuse 4 by this path, fuse 4 is also electrically connected with electric heating tube 1, for control electric heating tube 1 and power supply separated/be connected.
Shown in accompanying drawing 4 and accompanying drawing 5, in the present embodiment, the live wire and the zero line that connect electric heating tube 1 are connected two relays respectively, by the connection between two Control electric heating tubes 1 and power supply, only have after two relays are simultaneously closed, electric heating tube 1 is just connected with power supply, and reduction relay misses adhesive and causes the probability of electric heating tube 1 fault open.
The guard method of the electric heater frost protection system of the present embodiment is as follows: first closed two relays make electric heating tube 1 and power supply connect simultaneously, and electric heating tube 1 runs heating.In the running of electric heating tube 1, its heat is passed on Kick type temperature detect switch (TDS) 3 by the heat-transfer path of " electric heating tube 1-heat-transfer metal plate 2-Kick type temperature detect switch (TDS) 3 " by the heat that electric heating tube 1 sends; Meanwhile, by the heat-transfer path of " electric heating tube 1-heat-transfer metal plate 2-Kick type temperature detect switch (TDS) 3-fuse 4 ", heat is passed on fuse 4.In the running of electric heating tube 1; if occur because of the reasons such as blower fan is abnormal cause electric heating tube 1 temperature too high and reach the operating temperature to Kick type temperature detect switch (TDS) 3 time; Kick type temperature detect switch (TDS) 3 disconnects rapidly; cut off the connection between electric heating tube 1 and power supply; electric heating tube 1 is made to stop heating, the air-conditioning equipment of protection electric heating tube 1 and this electric heating tube 1 of employing.When Kick type malfunctioning switch; if the constant temperature of electric heating tube 1 raises and reaches to the fusing-off temperature of fuse 4; fuse 4 just can cut out electric heating tube 1 in the mode of fusing, makes electric heating tube 1 stop heating, protection electric heating tube 1 and the air-conditioning equipment adopting this electric heating tube 1.
The electric heater frost protection system configuration of the present embodiment is simple; highly sensitive, solve the problem that temperature sense in prior art is slow, make electric heater frost protection system more safe and reliable; the fuse 4 simultaneously arranged can make system have the effect of multiple protective, further elevator system fail safe.
