Abstract

The utility model discloses an electrified automatic alarm ground wire clamp comprising a handle and a clamp body connected with the handle, wherein the clamp body comprises a fixed outer frame and a pressing piece; the pressing piece and an operating handle are movably connected; a spring is arranged between the pressing piece and the fixed outer frame; and the fixed outer frame is provided with an induction type electric test alarm mechanism. As the clamp body is provided with the induction type electric test alarm mechanism, an induction electric test device gives the alarm in the situation of ensuring safe distance to remind an operating personnel of stopping hanging the ground wire when the operating personnel approaches the ground wire to an electrified transmission line and equipment by mistake. The ground wire clamp can avoid swart power grid blackout and an accident of personal injury and establish permanent safety guarantee for the personnel hanging the ground wire.

Description

Charged automatic warning earth connection clamp
Technical field
The utility model belongs to the power construction technical field of tools, particularly a kind of charged automatic warning earth connection clamp.
Background technology
The suspension of earth connection in the power industry has strict regulation in the rules, need really hang earth connection again behind the no-voltage to transmission line and the electrical verification of power transmission and transforming equipment elder generation.
In some transmission lines and transformer station since to galvanoscopic do not deposit, safeguard carry out as requested, cause electroscope cisco unity malfunction when needs use, at this moment a few thing personnel are off one's guard, judge that by rule of thumb transmission line and equipment is whether charged after, just hang earth connection; And at a few thing scene, the location complexity, charging equipment is concentrated, alive circuit indicates unclear, when having complex situations such as setting up many transmission lines on the same shaft tower, staff's mistake is suspended on earth connection on the charged equipment and circuit, causes pernicious grid power blackout, human casualty accident.The accident of charged hanging earthing conductor happens occasionally in some industrial enterprise and electric power system, causes serious personal injury and economic loss.
The utility model content
The utility model provides a kind of charged automatic warning earth connection clamp that can carry out the ground connection operation safely to circuit.
A kind of charged automatic warning earth connection clamp, comprise handle and be connected tong bodies with handle, described tong bodies comprises fixedly housing and compressing tablet, described compressing tablet and operating handle flexibly connect, described compressing tablet and spring fixedly is set between the housing is provided with induction type electrical verification alarm mechanism on the described fixedly housing.
Because the utility model is provided with induction type electrical verification alarm mechanism on tong bodies, when operating personnel miss close charged transmission line of earth connection and equipment, guarantee safe distance under the situation induction electroscopic device report to the police, remind operating personnel, stop hanging earth connection.Can avoid pernicious grid power blackout, human casualty accident to take place.For the hanging ground-wire personnel have set up permanent safety guarantee.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of charged automatic warning earth connection clamp, comprise handle 1 and be connected tong bodies with handle 1, described tong bodies comprises fixedly housing 2 and compressing tablet 6, described compressing tablet 6 flexibly connects with operating handle 3, described compressing tablet 6 and spring 5 fixedly is set between the housing 2 is provided with induction type electrical verification alarm mechanism 4 on the described fixedly housing 2.
Selection (is example with the clamp-type earth connection with 10KV transformer station), the induction electroscope of selecting should meet following requirement: sensitivity: pass through field test, select and to guarantee to respond to electroscopic device and charging equipment under the 10kV electric pressure outside safe distance, the induction electroscope that accurately gives the alarm.Reliability: the clamp-type earth connection that must the induction electroscopic device be installed by field test is not reported by mistake in certain limit voltage.Adaptability: according to the earth connection clamp or the profile of hook, select volume, weight is suitable, can not hang and deposit to earth connection to bring inconvenience.Economy: the selectivity price ratio is high, can not bring heavier financial burden because of technological transformation.
Type of device 10KV voltage alarm distance 5KV voltage alarm distance 1KV voltage alarm distance Volume (mm) Weight (gram)
Voice electrical verification warning device 40±1cm 20±1cm 4±1cm Long: 53 is wide: 75 height: 17 55
In installation process, at first consider fail safe, guarantee that earth connection is apart under the charging equipment situation enough far away alarm signal taking place.

Claims (1)

1. charged automatic warning earth connection clamp, comprise handle and be connected tong bodies with handle, described tong bodies comprises fixedly housing and compressing tablet, described compressing tablet and operating handle flexibly connect, described compressing tablet and spring fixedly is set between the housing is characterized in that: induction type electrical verification alarm mechanism is set on the described fixedly housing.
