Abstract
The utility model discloses a kind of prepackage type case and become room temperature automatic controller, comprise A.C. contactor, temperature sensor, ventilating fan and three phase mains, the one end of the contact switch that three phase mains is corresponding with A.C. contactor is respectively connected, and in A.C. contactor, the other end of contact switch is connected with ventilating fan respectively; The A phase of described three phase mains is connected with one end of normal open switch in temperature sensor, and in temperature sensor, the other end of normal open switch is connected with one end of A.C. contactor coil, and the other end of A.C. contactor coil is connected with the C phase of three phase mains; The utility model prepackage type case becomes room temperature automatic controller and prepackage type case change reduction indoor temperature can be prevented too high, and make electric equipment aging, burn out switch etc., make in-box electric appliance not reduce useful life by temperatures involved, and the utility model prepackage type case change room temperature automatic controller have simple, the intelligentized feature of structure.
Description
Technical field
The utility model relates to electric power infrastructure device field, and particularly a kind of prepackage type case becomes room temperature automatic controller.
Background technology
In prior art because prepackage type case become heat that transformer body in use sends and summer outdoor temperature too high, temperatures as high in switch gear room 75 degree, it is totally enclosed for adding casing, make indoor-outdoor air can not convection current, touch and make transformer, switch, instrument accelerated ageing, make transformer undercapacity, even burn out; Not only affect the normal operation of power supply unit, and staff detects and there is potential safety hazard when safeguarding.
Utility model content
The purpose of this utility model is to provide simple, the intelligentized prepackage type case of a kind of structure to become room temperature automatic controller.
The technical solution realizing the utility model object is:
A kind of prepackage type case becomes room temperature automatic controller, comprise A.C. contactor, temperature sensor, ventilating fan and three phase mains, the one end of the contact switch that three phase mains is corresponding with A.C. contactor is respectively connected, and in A.C. contactor, the other end of contact switch is connected with ventilating fan respectively; The A phase of described three phase mains is connected with one end of normal open switch in temperature sensor, and in temperature sensor, the other end of normal open switch is connected with one end of A.C. contactor coil, and the other end of A.C. contactor coil is connected with the C phase of three phase mains.
The utility model compared with prior art, its remarkable advantage:
The utility model prepackage type case becomes room temperature automatic controller and prepackage type case change reduction indoor temperature can be prevented too high, and make electric equipment aging, burn out switch etc., make in-box electric appliance not reduce useful life by temperatures involved, and the utility model prepackage type case change room temperature automatic controller have simple, the intelligentized feature of structure.
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is the fundamental diagram that the utility model prepackage type case becomes room temperature automatic controller.
Embodiment
As shown in Figure 1:
A kind of prepackage type case becomes room temperature automatic controller, comprise A.C. contactor 1, temperature sensor 2, ventilating fan 3 and three phase mains, the one end of the contact switch that three phase mains is corresponding with A.C. contactor 1 is respectively connected, and in A.C. contactor 1, the other end of contact switch is connected with ventilating fan 3 respectively; The A phase of described three phase mains is connected with one end of normal open switch in temperature sensor 2, in temperature sensor 2, the other end of normal open switch is connected with one end of A.C. contactor 1 coil, and the other end of A.C. contactor 1 coil is connected with the C phase of three phase mains.
Described A.C. contactor 1 adopts the A.C. contactor of CJ-10/10A.
The power of described ventilating fan 3 is 60W.
Below by embodiment, the utility model is described further:
A kind of prepackage type case becomes room temperature automatic controller, comprise A.C. contactor 1, temperature sensor 2, ventilating fan 3 and three phase mains, the one end of the contact switch that three phase mains is corresponding with A.C. contactor 1 is respectively connected, and in A.C. contactor 1, the other end of contact switch is connected with ventilating fan 3 respectively; The A phase of described three phase mains is connected with one end of normal open switch in temperature sensor 2, in temperature sensor 2, the other end of normal open switch is connected with one end of A.C. contactor 1 coil, and the other end of A.C. contactor 1 coil is connected with the C phase of three phase mains.
Described A.C. contactor 1 adopts the A.C. contactor of CJ-10/10A, and wherein the contact switch of A.C. contactor is normally open.
The power of described ventilating fan 3 is 60W.
Operation principle of the present utility model:
The utility model prepackage type case becomes room temperature automatic controller, switches on power, when the temperature inside the box reaches certain value, temperature inductor action, makes to close at the normal opened contact opened at ordinary times, switches on power and A.C. contactor action is closed a floodgate, ventilating fan obtains electric rear work, temperature is declined temperature inductor action when reaching certain value, cuts off the electricity supply rapidly, make ac contactor coil action, opening power, ventilating fan dead electricity, whole end-of-job, reaches the object that the temperature in case is declined.
