Abstract
The utility model provides a portable resistance box which comprises a portable box body, wherein a plurality of resistors are arranged in the box body; each resistor is provided with a terminal for wiring when the resistors are connected in series; the resistors are arranged in a lower cavity of an operating panel in the box body, and the terminals are arranged on the operating panel; the upper end of the box body is provided with an openable upper cover; when the upper cover is closed, the upper cover is temporarily locked with the box body through a clamp; and the upper cover is also provided with a hand grip. According to the utility model, the resistors can be selected for current limiting according to needs, thereby avoiding discharge and incapability of current limiting in the testing process. A current of 1mA is allowable for each resistor. A current protector can also be added to perform automatic shutdown. The portable resistance box is reasonable in structure, simple to operate and beneficial to popularization.
Description
Technical field
The utility model relates to a kind of portable resistor case that is convenient for carrying and operates.
Background technology
Originally use 10KV lightning arrester, cannot current limliting in the process of test and there will be electric discharge phenomena.
Summary of the invention
Goal of the invention: the utility model provides a kind of portable resistor case, and it is connected on lightning arrester tail end, its objective is that solution had electric discharge and problem that cannot current limliting in the past in test process.
Technical scheme: the utility model is achieved through the following technical solutions:
A kind of portable resistor case, is characterized in that: this resistance box comprises a portable casing, is provided with multiple resistance in casing; While being provided with series resistance on each resistance, for the terminals of wiring, resistance is arranged in the lower cavity of the operating operation panel in casing, and terminals are arranged on guidance panel; In the upper end of casing, be the upper cover that can open, when upper cover is closed, by pintle hook lock and casing, lock temporarily; Upper covering, be also provided with carrying handle.
In casing, be also provided with ammeter, reading panel and the binding post of this ammeter are arranged on guidance panel.
High 300mm, 300mm and the 200mm. of being respectively of length and width of casing.
The bottom of the guidance panel in this casing is also provided with current protective device.
Advantage and effect:
The utility model provides a kind of portable resistor case, and this resistance box comprises a portable casing, is provided with multiple resistance in casing; While being provided with series resistance on each resistance, for the terminals of wiring, resistance is arranged in the lower cavity of the operating operation panel in casing, and terminals are arranged on guidance panel; In the upper end of casing, be the upper cover that can open, when upper cover is closed, by pintle hook lock and casing, lock temporarily; Upper covering, be also provided with carrying handle.
The utility model can select resistance to carry out current limliting voluntarily, and preventing has and discharge and do not have metering function in test process.Require each resistance can flow through 1mA electric current.Can also add current protective device, automatically disconnect.
The utility model is rational in infrastructure, easy and simple to handle, is beneficial to and applies.
Accompanying drawing explanation:
Fig. 1 is the utility model structural representation.
Fig. 2 is end view of the present utility model.
Embodiment: the utility model is further described below in conjunction with accompanying drawing:
As shown in Figure 1, the utility model provides a kind of portable resistor case, and this resistance box comprises a portable casing 2, is provided with multiple resistance in casing 2; While being provided with series resistance on each resistance, for the terminals 5 of wiring, resistance is arranged in the lower cavity of the operating operation panel 7 in casing 2, and terminals 5 are arranged on guidance panel 7; In the upper end of casing 2, be the upper cover 1 that can open, when upper cover 1 is closed, by pintle hook lock 3 and casing 2, lock temporarily; On upper cover 1, be also provided with carrying handle 4.
In casing 2, be also provided with ammeter 6, reading panel and the binding post of this ammeter 6 are arranged on guidance panel 7.
High 300mm, 300mm and the 200mm. of being respectively of length and width of casing 2.
The bottom of the guidance panel 7 in this casing 2 is also provided with current protective device.
When the utility model is used, by portable this portable resistor case position to needing to use, open upper cover 1, utilize binding post that the resistance of needs is cascaded, then this resistance box is connected to lightning arrester tail end, the utility model can select resistance to carry out current limliting voluntarily, and preventing has and discharge and do not have metering function in test process.Each resistance can flow through 1mA electric current, and electric current is checked by ammeter.The utility model can also utilize and add current protective device circuit is protected, and during current overload, automatically disconnects.
