Abstract
The utility model provides an electric control box with the function of cold prevention, which mainly comprises a box body (7), a guide rail (4) and a terminal board (6), wherein the box body (7) is provided with a temperature control system. The temperature control system comprises a circuit breaker (1), a temperature controller (2) and a heater (3) which are connected together in turn by using electric wires. The utility model can realize the automatic control of environmental temperature in the electric control (operation) box and solves the problem that electronic components can not run normally under a low-temperature environment. The utility model is steady in running, has the characteristics of high safety and reliability and the like and is convenient to maintain. The utility model provides relaxed installation allowance to the electric equipment of factories positioned in cold regions and has extensive application prospect.
Description
Technical field
The utility model relates to a kind of electrical control (operation) case, especially a kind of electric control box that has the winter protection function that is adapted at the place installation of the outdoor low temperature of severe cold area.
Background technology
Along with the raising of electric equipment automatization level, the control that has electric component group and become, the electric equipment of demonstration often are installed in electrical control (operation) case.Electronic building brick has requirement to environment, particularly temperature environment is very big to the work influence of electronic building brick, but general electronic building brick operate as normal between 0 ℃～40 ℃, and the electronic building brick of special screening can be worked under-20 ℃～45 ℃ environment, when temperature is low again, the electronic building brick cisco unity malfunction.For guaranteeing the operate as normal of electronic building brick, several method is arranged: 1. install in the suitable place of environment; 2. protect with insulation material.More than two kinds of cost height that method has, the need that have are provided with control (operation) chamber and guarantee the place of electronic device works temperature.
The utility model content
The purpose of this utility model is with a kind of electric control box that has the winter protection function is provided, by utilizing electric power energy, adopt temperature controlled method, realization has solved the problem that electronic building brick can not normally move to the automatic control of ambient temperature in electrical control (operation) case under low temperature environment.
The purpose of this utility model is achieved in that a kind of electric control box that has the winter protection function, mainly comprises casing, guide rail, terminal board, and a temperature control system is installed in casing.Temperature control system comprises circuit breaker, temperature controller, heater.With electric wire circuit breaker, temperature controller, heater are coupled together, the front end of circuit breaker is received on the power supply in the electric cabinet with electric wire.Circuit breaker is used for the route protection of temperature control system, and the temperature inside the box scope is set on the thermostat, and temperature controller is controlled heater in the design temperature scope.Be set at-5～20 ℃ of scopes as case inner control temperature, when the temperature inside the box is lower than-5 ℃, the temperature controller junction closure, heater work, when the temperature inside the box was higher than 20 ℃, the temperature controller contact disconnected, and heater stops.
The utility model is owing to installed temperature control system in electrical control (operation) case, realized the low temperature environment protection of electrical control (operation) case, guaranteed the temperature requirement of electronic building brick in the case, solved the problem that electronic building brick can not normally move under low temperature environment.Have operate steadily, safe and reliable, be convenient to characteristics such as maintenance.
Description of drawings
Fig. 1 is the structural representation of the utility model electric control box;
Fig. 2 is temperature control system control principle figure in the utility model.
Wherein, the fault contact 22 of the state contact 11 of circuit breaker 1, temperature controller 2, heater 3, guide rail 4, PLC module 5, terminal board 6, casing 7, central control station 8, circuit breaker, temperature sensor 21, temperature controller.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further.
As shown in Figure 1, 2, a kind of electrical control (operation) case that has the winter protection function of the present utility model mainly comprises casing 7, guide rail 4, terminal board 6, and a temperature control system is installed in casing 7.Temperature control system comprises circuit breaker 1, temperature controller 2, heater 3, the power supply of temperature control system is taken from the power supply in electrical control (operation) case, according to the order of connection of temperature control system pie graph, each electric equipment of temperature control system is coupled together with electric wire.A circuit breaker 1 is protected as temperature control system; Guide rail 4 is used for the fixing of each electric equipment; Temperature controller 2 is nucleus equipments of temperature control system, operational environment requirement according to electric equipment in the case, the temperature controlling range of artificial design temperature controller 2, temperature sensor 21 in the temperature controller 2 carries out work according to setting range, when the temperature inside the box is lower than setting range, temperature controller 2 control heaters 3 are started working, and when the temperature inside the box was higher than setting range, temperature controller 2 control heaters 3 quit work.
As shown in Figure 2, the state contact 11 of circuit breaker and the fault contact 22 electricity consumption line generalizations of temperature controller are got up, receive on the PLC module 5 (or terminal board) in the case, monitor by the central control station 8 that netting twine (or electric wire) send.In a single day temperature control system breaks down, and centralized monitoring system is reported to the police, and the attendant gets rid of the fault of electrical control (operation) oven temperature, degree control system, and making electrical control (operation) case be installed in the interior electric equipment of low temperature environment nowel can operate as normal.
The utility model is applicable under the low temperature environment can not normally move miscellaneous equipment, and equipment is packed into to be had in the fully sheathed case of temperature control system, and equipment just can be worked under the temperature conditions that allows.
The utility model electrical control (operation) case provides to the factory that is positioned at cold district nargin is installed widely, particularly in the place that does not have heating condition, embodies its advantage more.In the epoch of electric automatization control field develop rapidly, the enforcement of computer distribution system networking implements to have increased loose condition for the factory that is positioned at cold district.
